How To Age A Cat

How to Determine the Age of Cats and Kittens

There are many mysteries surrounding cats who have been adopted or rescued, and one of the most intriguing is the feline’s age. A veterinarian is your greatest resource for assessing the present age of a cat, as well as for developing a care package that will provide the cat with the highest possible quality of life and longevity. A comprehensive veterinary examination of the cat’s whole body will typically assist in determining the cat’s approximate age; however, veterinarians tend to focus their attention on a few body regions in particular when attempting to estimate the cat’s age.


The first baby teeth of a cat appear between the ages of 2 and 4 weeks, making teeth an useful indicator of a kitten’s age in early stages. Their permanent teeth are forming above and below the baby teeth, and by the time the kitten is 3 to 4 months old, the permanent teeth will begin to displace the baby teeth, causing the cat to lose its teeth (also called deciduous teeth). Typically, by 6 months of age, all of the adult teeth are in place, and the development of the cat’s teeth is no longer relevant in establishing the cat’s age.

However, with the availability of pet dental cleaning solutions, tartar may not be a reliable sign of dental disease in cats, depending on the devotion with which the cat’s carer implements a dental care program.

Sexual Maturity

It is possible for male cats to attain sexual maturity as early as 6 months of age. Puberty is characterized by the territorial spraying of urine testicles and the development of more prominent testicles. Female cats will normally go into heat (have their first estrus cycle) between the ages of 5 and 9 months, while the duration of daylight and the weight of the cat can also have an impact on when the queen goes into heat (or has her first estrus cycle). An estrus-experiencing female cat will communicate with you in a highly visible and noisy manner.

Many vets, on the other hand, are increasingly promoting early spay and neuter.

As a result, calculating the age of a cat might be a little more difficult.

Coat Development

The fur or hair of a kitten is baby-fine and silky, but as a cat grows older, its coat will thicken and become coarser. It may also change color, becoming darker or lighter in tone depending on the environment. When a cat reaches senior status, it may even develop patches of white or gray individual hairs, similar to what happens to people as they get more senior. While not a guarantee of age, a cat’s coat can assist a veterinarian in determining the age of a cat.

Additionally, the manner in which a cat brushes itself might provide clues as to the age of the animal. Cats are notoriously clean creatures, but as they age and gain weight, as well as when they are suffering from dental issues or arthritis, they may become less diligent about cleaning themselves.


In their maintenance years, healthy kittens and cats have eyes that are extremely clear and brilliant, with no indication of tears or discharge. Although it is rare for cats to have clouded eyes in their older years, some do experience tears and/or discharge in their latter years. This normally doesn’t happen until the cat is at least 10 years old, if at all. If you have any reason to believe your pet is unwell, contact your veterinarian immediately. Always consult your veterinarian for health-related inquiries, since they have evaluated your pet and are familiar with the pet’s medical history, and they can provide the most appropriate suggestions for your pet.

How to Tell a Cats Age: 5 Sure Methods

Cats mature in an elegant manner. Even though it’s easy to distinguish between a kitten and an adult cat, it can be difficult to determine the age of a cat once it reaches the adult stage. For the most part, an adult cat resembles a senior cat in terms of appearance. Most cats are adults between the ages of 9 and 12 months, which makes estimating their age even more difficult. If you’re wondering how to identify the age of a cat, you should be aware of these five reliable methods for determining the age of your cat.

First, a Primer on Cat Ages

Before we get into how to identify a cat’s age, let’s have a look at the many stages of a cat’s life. A cat’s life is divided into six phases. From the age of 0 to 6 months, they are kittens. Kittens are little, cute creatures who are constantly exploring their surroundings in order to have a better understanding of their surroundings. Felines enter the junior stage between the ages of 7 and 24 months. Juniors are growing more self-sufficient and preparing for the shift from being in their prime years to being in their late twenties.

  1. When your cat is most awake and capable, it is during this period that you should pay attention.
  2. Your cat will be fully grown when he reaches the age of seven.
  3. After fifteen years, they will have reached the age of geriatrics.
  4. It is difficult to distinguish between a seven-month-old cat and an eight-month-old cat, but as we will see, it is rather simple to establish whether your cat is in its junior years or whether it is of the senior cat age.

How to Tell a Cat’s Age: Look at Their Teeth

The teeth of a cat are an excellent predictor of its age. First and foremost, a cat’s teeth do not fully develop until they are roughly six months old, so if you peek inside their mouth and notice any missing teeth, you know you have a kitten. For the second time, if you have an adult cat who still has all of his or her teeth, you may occasionally tell the feline’s age by looking at the stains on the cat’s teeth. Their teeth get more discolored as they consume more food. Consequently, if you notice gleaming whites, you have a younger cat on your hands.

If you see a feline with older teeth, it’s possible that you’re looking at an older feline. Of course, this approach is only an approximation, but it can at the very least assist you in forming an educated guess as to how old the cat might be.

The Softness of Their Coat

The fur of a kitten is soft, silky, and smooth to the touch. It’s lovely and very clean. However, just like with human hair, the cat’s fur coat gets less silky with age, just as it does with human hair. They may also grow patches of grey or white fur on their heads (much as people do on their skulls!) if they are exposed to the elements. A veterinarian who has seen hundreds of cats and touched countless coats of fur may often have a very decent feel of how to identify a cat’s age simply by caressing them!

Cloudy Eye Appearance or Discharge

For the most of their lives, cats have eyes that are quite bright and clear. Cats do not acquire eye issues until they reach the senior stage of life (around the age of 10 years). Consequently, if your cat has foggy eyes or any eye discharge, this is a definite sign that you have a senior or geriatric cat on your hands.

Mobility and Activity Levels

Cats over the age of ten like sleeping, whereas kittens enjoy playing. While some senior cats are still energetic and spry, the general rule is that the older the cat gets, the more sedentary it will become in general. Senior cats and kittens require almost the same amount of sleep each day – approximately 20 hours. Adult cats, on the other hand, require between 12 and 15 hours of rest every day to function properly. Again, much of this is dependant on the cat, but if you keep track of how much time your cat spends resting over a few days, you should be able to determine if they are an adult cat or a senior cat.

Use a Cat Age Chart

There are several cat age charts available on the internet, each of which includes photographs of cats at various phases of their lives. If you come across one, you may utilize it as a starting point. Take a look at your cat and see how it compares to the others you see. The cat may appear younger, like the junior cats, or older, like the senior cats, depending on how you look at it. Cat age charts may be used to determine the age of your feline companion, no matter where they are located.

How to Tell a Cat’s Age: Possible, But Tricky

As we’ve seen, a few characteristics of your cat can help you determine its age within a range of possibilities. Kittens are distinguished by having a lot of activity, seeming smaller than their adult counterparts, having soft fur, and not having all of their teeth. The chances are that you’re looking at a cat in its prime if they’re still full of activity and have sleek coat, yet they’ve lost none of their teeth. If you are looking at a cat with discharge from its eyes, a duller coat, and less activity, you are most likely looking at a senior cat (also known as a senior cat).

Because they have seen so many cats previously, they are frequently able to make amazingly accurate judgments about the age of the felines they encounter.

How do cats age?

Overall, cats grow older by being slower, having a less lustrous coat, and sleeping more. Younger cats, on the other hand, are more energetic, have a softer fur coat, and sleep less hours each day.

Do cats age like dogs?

Yes, in the majority of cases.

When it comes to aging, both dogs and cats exhibit qualities that are comparable.

How do you tell the age of a cat?

Observing a cat’s behavior is the most accurate approach to determine its age. Cats who are older or very young require a great deal more sleep. Cats that are in their prime require the least amount of rest. Young cats are full of activity and like engaging in playful activities. Older cats may want to retire to their sleeping quarters. Even just observing the cat’s activity patterns will give you a reasonably decent idea of how old the cat is. Check visit our blog and follow me on LinkedIn to keep up with the latest news!

How to tell your cat’s age in human years

Cats live for an unusually lengthy period of time considering their size. In general, the length of life of an animal is proportionate to its size (with the exception of tortoises, man and a few other animals). A little mouse has a short lifetime, a rabbit a little longer, and a dog between 7 and 20 years, depending on its breed or size, its activity level, or a combination of the two, are typical. Even though cats are not significantly larger than rabbits, they live for an average of 12–14 years, with some cats living into their late teens or even early twenties.

There are 6 life stages for cats:

  • Cats at their kitten stage are between 0 and 6 months old, during which time they are developing fast and are typically not yet sexually mature.
  • 7 months to 2 years: During this period the cat grows to its full size and learns everything there is to know about life and how to survive it. The cat is at its prime between the ages of 3 and 6 years, when it is physically and behaviorally mature while still being healthy and energetic, appearing sleek and glossy and making the most of life
  • Mature — After 7–10 years, the cat has reached what we refer to as ‘Mature,’ which is about equal to humans in their mid-40s to mid-50s. A senior cat is one who has lived for 11–14 years, which is roughly the equal of 70 human years. Super Senior – 15 years and older Many cats reach this stage of life, with others exhibiting no indications of being so old as to be considered super senior.

The phases are shown in the table below, along with the human age that corresponds to each stage. It is via these stages that we may gain an understanding of how old the cat is on the inside, which is not often visible from the exterior, since cats rarely grow grey or display external indicators of suffering or sickness, such as arthritis, as has been pointed out. Cat Care for Life is a preventative healthcare project launched by International Cat Care, which stands for Cat Care for Life. The program examines the kind of health examinations your cat should have based on its age, as well as the types of age-related changes you should anticipate to observe in your cat.

Because many cats enter shelters and rescues from the streets, many pet owners acquire cats and kittens without knowing the precise age of the animals they are adopting. Knowing the age of your cat or kitten is not required, but it might assist you in determining the appropriate nutrition and care for them. Take a look at the teeth. A cat’s age may often be determined with more accuracy the younger the cat is when it is examined. Identifying the age of your cat gets substantially more difficult if they have already developed their adult teeth.

  • When kittens are approximately 2-4 weeks old, they obtain their baby incisors, and when they are 3-4 weeks old, they receive their canines.
  • Kittens begin to lose their baby teeth at the age of 4 months, and the adult teeth begin to develop at this time as well.
  • It might be difficult to determine the age of a cat based on teeth that are more than 6 months old.
  • If there is tartar buildup on all of the cat’s teeth, the cat is most likely between the ages of 3-5 years.
  • In certain cases, missing teeth might be an indication that a cat is around 10-15 years old.
  • However, this is only accurate up until the child is around 6 months old.
  • Feel the cat’s body and muscles if he or she permits it.
  • An aged cat may have excess, drooping skin on its body.
  • Age-related cataracts can occur in cats, just as they can in humans and dogs.
  • Activity The level of activity exhibited by a cat is an evident trait that may be used to assess its age.

Pet cats, especially kittens and young cats, are far more lively and energetic than their senior cat counterparts. Older cats tend to spend more time lying around and less time playing with toys, whether it’s because of arthritis or just because they’re getting on in years.

Determining Your Cat’s Age

If you haven’t had your cat since he was a kitten, it might be difficult to know how old your cat is. To give better age-appropriate care for your kitty, it is helpful to know approximately how old your cat is. Depending on the results of blood and organ tests, your veterinarian can estimate the age of your cat, but for the rest of us, here’s a small guidance to help!

Let’s begin with kittens.

When judging the age of young kittens, it is easiest to look at their early developmental signs:

  • Older than one day: Ears are curled and eyes are closed. Kittens will be unable to stand on their own
  • Ears will begin to open up after three days. 6 days old: The eyes will begin to open a sliver of an inch or two. Despite the fact that their ears will open, kittens will be unable to hear anything. Kittens will begin to crawl shortly after birth. Eyes will be fully open, but pupils will not dilate, until the child is 10 to 15 days old. Kittens will begin to walk when they are two weeks old, but they will be shaky and clumsy in their movements. Kittens will now respond to sound since their ear canals are now open at three weeks of age. They will be able to walk more confidently, will be able to use the litterbox, and their baby teeth will begin to emerge
  • Playing, pouncing, rough-housing, and self-grooming begin when the puppy is 4 to 5 weeks old. Kittens’ eyes will shift from blue to their permanent hue by the time they are six weeks old. Kittens should weigh 2 pounds at 8 weeks of age and be of sufficient size to be spayed or neutered. They will have the appearance of little replicas of full-grown cats. When an animal is young, you can tell more about its age than you can when it is older, just like puppies.

Let’s talk about Cat Teeth:

Your kitten will have all of its baby teeth by the time it is 8 weeks old, including the Incisors, Canines, and Molars. The permanent adult teeth will begin to erupt over the top of the baby teeth at the age of 3.5 to 4 months. Your cat will have all of its dazzling white adult teeth by the time he or she is six months old. Around the age of two, teeth may begin to fade and become discolored. When children are between the ages of 3 and 5 years old, they may begin to develop a small amount of tartar around the gum line (particularly on the molars), as well as obvious tooth wear.

  1. You might also wish to experiment with providing your cat tasty dental treats.
  2. The majority of kittens will attain their full size by the time they are one year old.
  3. In most cases, if your cat still has that “teenager” appearance, he is under the age of one.
  4. This cat’s paunch first appeared when she was about 2 years old.
  5. A cat is called a senior when it is between the ages of 8 and 10 years old.

An indoor cat will age approximately 4 human years for every one cat year, and an outdoor cat will age approximately 8 human years for every one cat year. This is an other good argument for keeping your cat indoors.

When a kitten is born, it has dense, short hair on its body and legs. As they grow older, their fur grows softer and finer in texture. When a cat achieves senior status, its hair gets thick and coarse once more, and it may even become grey in some areas.

Changes in Muscle Tone:

Because they are more active, younger cats will have greater muscular tone than older cats. Older cats may have saggier skin and more boniness on the rear and shoulder blades than younger cats. An outdoor-living cat is considered to age nearly twice as quickly as an indoor cat, according to some sources. An indoor-only cat would be 72 human years old at the age of 14 cat years, whereas an outdoor cat would be 120 years old at the age of 14 cat years. This pace of aging begins to manifest itself at the three-year mark.

The lifespan of a cat is around 15 years when it reaches the age of almost one year.

The life expectancy of an indoor cat is around 4 human years for every cat year, whereas the life expectancy of an outdoor cat is approximately 8 human years for every cat year.

Not only will you keep them secure from all of the hazards of the outdoors, but they will likely have a much longer life and be much easier to care for in the long term as a result of your efforts.

How to Know Your Cat’s Age

Documentation Download Documentation Download Documentation Unless you were present at the time of your cat’s birth, ascertaining the age of your cat might be challenging. You can, however, determine its approximate age by observing certain characteristics of your cat. Cats tend to display signs of aging in their teeth, hair, eyes, and temperament as they become older. You may search for these indicators yourself to obtain an idea of how old your cat may be, and a veterinarian may be able to provide you with the most accurate answer.

  1. 1 Count the number of teeth on your cat’s molars. With time, your cat’s dental growth will go through a number of phases. As soon as your cat is relaxed and comfortable, attempt to identify the different sorts of teeth it has in order to gain an indication of how old it is
  • The incisors (which appear between 2 and 4 weeks) and canines (which appear between 3 and 4 weeks) are the first teeth to appear in a kitten, followed by the premolars (which appear between 4 and 6 weeks). A cat that is less than 4 months old will not have its first set of molars. Your cat will have all of its adult teeth when it is between the ages of 6 months and 1 year old, approximately. This is the moment at which the cat’s teeth should be bright white and show no indications of wear.
  • 2 Check your cat’s teeth for signs of yellowing. As your cat grows older, the appearance of its teeth will begin to reveal indicators of that maturation. If your cat’s teeth are yellowing, it may be an indication that he is an older adult. The degree of wear and yellowing on your cat’s coat will suggest how old he or she is likely to be.
  • By the time your cat is 2 years old, you should expect to notice a mild yellowing of his or her teeth. Your cat’s teeth will get more yellow when it is between the ages of 3 and 5 years old. When a child is between the ages of 5 and 10, yellowing will be noticeable. When your cat is 10 years old or older, it will exhibit obvious indications of yellowing, which will most likely be present on all of its teeth.

  • s3 Keep an eye out for symptoms of wear and tear on your cat’s teeth. Another indication of your cat’s age that may be observed in his teeth is the amount of wear he has sustained. Using a magnifying glass, carefully check your cat’s teeth for any worn regions that may indicate how old your cat could be.
  • Teeth that have been worn down will have lost their tips and will seem more dull than teeth that have been worn down in a younger cat. Some teeth may have their tips worn down or snapped off completely. When your cat reaches the age of 5 years, it will often begin to exhibit indications of tooth wear. If your cat is between the ages of 5 and 10 years old, his or her teeth will be showing symptoms of wear. When children reach the age of ten and beyond, they will notice a significant wear down of their teeth. At these ages, it is possible that some teeth are missing. It is more likely that an older cat may develop dental tartar and gum recession as a result of its age. Because the rate at which the cat’s teeth grow unclean is dependent on the cat’s food, this is a somewhat ambiguous method for aging.
  1. 1 Examine your cat’s coat to see how thick it is. Depending on how old your cat is, the thickness of his or her coat may be more or less. It is not normal for cats to go bald or lose their hair, but by evaluating how full their coat is, you may determine their age.
  • The coat of an elderly cat may be thinner than the coat of a younger cat, and vice versa. It is possible to have seasonal fluctuations. Generally speaking, summer jackets are thinner than winter coats. If your cat is losing its fur, take him or her to the veterinarian.
  • 2 Feel the feel of your cat’s fur with your fingers. Throughout your cat’s life, there are certain small alterations in the texture of its coat that you should be aware of. When you check for these differences, you might be able to obtain a fair idea of how old your cat really is.
  • Young cats will have smooth and dense coats of hair
  • Older cats will have a softer coat of hair. Cats that are older will most likely have coarser fur. In senior cats, patches of gray hair may emerge on their coats.
  • 3 Take note of the body type of your cat. The degree of activity in your cat will fluctuate as he or she gets older. It is possible that these variations in your cat’s activity level will result in alterations in his or her body form. If you look at the contour of your cat’s body, you might be able to guess its age.
  • Because of their high levels of activity, young cats have a tendency to be lean and muscular. Cats in their middle years may be more rounded and fleshed out. Cats that are older will most likely have prominent shoulder bones and loose skin.
  1. 1 Keep an eye on your cat’s mood. Cats that are older are more prone to have impaired eyesight and hearing, as well as to suffer from arthritis-related discomfort. It is possible that these situations will have an impact on your cat’s mood. If you find your cat engaging in any of the following activities, it may be an indicator that it is either unwell or approaching the end of its life
  • When you interact with your senior cat, it may become too aggressive
  • This is normal. Fear and anxiety can also worsen in senior cats as they become older.
  • 2 Keep an eye on your cat’s litter-box habits. If your cat is having difficulty using the litter box, it might be a sign of a number of various problems. Older cats, in particular, may have difficulty utilizing the litter box owing to health difficulties or a diminished capacity to cope with stress.
  • Reduced eyesight, inflammatory bowl disease, kidney or liver illness, and other medical conditions might make it difficult for senior cats to use the litter-box properly. Stress might cause an elderly cat to stop using his or her litter box entirely. Try to keep the surrounding atmosphere as tranquil as possible
  • 3 Pay attention to your cat’s sleeping routines. Most cats require more sleep as they grow older, and this is true for the majority of them as well. You should also keep note of when it sleeps, keeping an eye out for any changes in its sleeping pattern as it gets older.
  • Cats that are older may be prone to staying up all night and sleeping throughout the day. Cats that are older may also howl at night
  • As cats become older, their activity levels decline and they spend more of their time resting. When it comes to activity levels, younger cats will be more active and play more during the day, while senior cats would prefer to relax.
  1. 1 Look for any clouding in the sky. Depending on how old your cat is, its eyes may change from being brilliant and clear to being hazy and dull. You can tell how old your cat is by looking at his or her eyes and observing the degree of cloudiness or clarity in them.
  • Your cat’s eyes will be clear and brilliant, indicating that he or she is likely young. Age-related cloudiness in the eyes of older cats may be caused by the cat’s own age or the development of cataracts.
  • 2 Examine the pupil of the eye. The iris is the brightly colored portion of the eyeball that surrounds and protects the pupil. It is possible to determine the approximate age of your cat by looking at its iris. Look for any evidence of jaggedness or roughness in the iris while you do your examination
  • Irises that are clean and smooth will be found on younger cats. It is normal for cats to lose the thickness of their irises as they age, and strands will begin to develop in the iris, along with pigment patches.
  • 3 Keep a watch out for discharge or tears in the eyes. The tear ducts in your cat’s eyes, which are a good indicator of both age and health, might be a fantastic spot to check on your cat. Its eyes may become excessively watery from time to time, whether as a result of aging, disease, or injury. Elder cats are more prone than younger cats to suffer from runny eyes, as well as injury and disease, which might assist you in determining your cat’s age.
  • Cats under the age of one year should not have any visible rips or discharge. Older cats may appear to be weeping up or having discharge coming from their eyes. Runny eyes can also be an indication of sickness or injury, so consult your veterinarian if your pet has them.

  • If you are unclear about the age of your cat, consulting with your veterinarian is the most effective means of determining its age. The majority of the indications of old age might also be indicators of sickness. Always make an appointment with your veterinarian if you have any concerns about your health. If your cat is suffering from a severe illness that is causing them agony, do not allow them to suffer so that you can keep them. As your cat grows older, it becomes more susceptible to sickness.


About This Article

Summary of the Article It might be difficult to determine the age of your cat, but you may be able to establish its age by looking at its teeth. If your cat is younger than 6 months to a year old, it may not yet have all of its teeth, which are made up of incisors, canines, premolars, and molars. If your cat is younger than 6 months to a year old, it may not yet have all of its teeth. The cat’s teeth will begin to yellow between the ages of 2 and 5 years, and between the ages of 5 and 10 years, the yellowing will be plainly evident, and the teeth will begin to exhibit symptoms of wear and tear.

Cats may live for an incredibly long period of time given their little size. Although cats have longer lives than most other small animals, they have a lower lifetime in general. For example, despite the fact that cats are smaller than the majority of canines, they tend to have longer lives. Furthermore, despite the fact that they are just slightly larger than rabbits, they have far longer lives. Pet cats have an average lifetime of 13 to 14 years, which is about typical for their species. However, although their longevity varies, a well-cared-for cat is likely to live to be 15 years old or older, with some living to be 18 or 20 years old and a few exceptional felines even living to be 25 or 30 years old.

Assessing your cat’s age

The physical and behavioral development of cats occurs considerably more swiftly than that of humans, but once they reach their complete physical and behavioral maturity – at around 3 years of age – their external look remains relatively unchanged for many years. They normally still look to be quite young, and it might be difficult to tell the difference between a kitten and an adult cat at times. Despite the cat’s youthful external look, the cat will be growing older on the inside. The management of our cats’ life, health, and behavior becomes much simpler if we can correlate their age with the equivalent of our own human years, as shown in the chart below.

It should be noted, however, that this is an extremely primitive model that does not take into consideration a number of important characteristics of how cats develop and age.

With the help of the chart we’ve supplied (below), you may quickly and simply establish approximately how old your cat is in human years.

As you can see from the graphic, there are six distinct life phases for cats to consider.

Writer and dog-and-cat mom with a lot of content|+ posts A writer and former associate digital content editor at the American Kennel Club, Randa has written for a variety of publications. She is also the mother of one Corgi and two orange kittens. You’ve probably heard the expression that one year in the life of a cat is equivalent to seven years in the life of a person. What you may not have known is that this is a misconception about cats — and dogs, for that matter – that many of us have come to believe.

Generally speaking, it is believed that the “one year to seven years” estimate for both cat years and dog years was devised to simply highlight that our pets mature much more rapidly than do we.

How can you correctly convert the years of your cat’s life to those of humans?

How do I calculate my cat’s age in human years?

As a result, if you’re wondering, “How old is my cat in human years?” the answer is rather straightforward. In comparison to dogs, which have a broader range of ages depending on size and breed, the method used to determine a cat’s age is rather consistent. American Animal Hospital Association(AAHA) states that the following recommendations have been developed and agreed upon by the AAHA, Feline Advisory Bureau (formerly known as International Cat Care), and the American Association of Feline Practitioners(AAFP):

  • It is estimated that the first year of a cat’s life is equivalent to around 15 years in human years. When it comes to cats, the second year of their lives is equivalent to another nine years
  • A cat’s life span increases by one year every two years after the second year, and each extra year is comparable to approximately four human years.

So, how old is your cat in human years, in your opinion? You may find out by referring to the chart below that compares cat years to human years.

According to the above chart, the typical one-to-seven ratio is quite deceptive — cats mature far more rapidly in their first two years of life, and then the aging process slows down and continues more gradually after that. What factors led vets to arrive at this cat age to human age conversion? To put it another way, the American Animal Hospital Association (AAHA) claims that its criteria are based on the physical and behavioral changes that occur at different phases of a cat’s life, and that these stages are then linked with stages of human life.

To be sure, just like with people (and dogs), there will be some variety in the way your particular cat ages.

When it comes to dogs, smaller breeds are considerably more likely to survive for a longer period of time.

Do indoor and outdoor cats age the same way?

If your cat is an indoor cat or an indoor-outdoor cat, this may also have an impact on how old they are. In reality, the American Academy of Dermatology (AADH) acknowledges that this is a controversial subject and that there are good arguments on both sides of the debate. According to the American Animal Hospital Association, indoor cats are less likely to be subjected to trauma or exposed to certain infectious illnesses, which may result in longer lives. Indoor cats, on the other hand, may be more susceptible to sickness as a result of the limits of their habitat.

Although outdoor cats can benefit from being in a natural and exciting habitat, they are at a far higher risk of suffering stress and being ill as a result of their surroundings.

When it comes to deciding which of these lifestyle alternatives is best for their cat, the final decision is entirely up to them. It’s important to keep in mind, however, that your selection may have an impact on the way your cat ages.

What are the signs of a senior cat?

With this in mind, there are several physical clues that can assist you in determining the age of your own cat, particularly when your adult cat enters the senior life stage.

  • Discoloration on the teeth, tartar buildup on the teeth, missing teeth
  • The coat is graying and thicker and coarser in contrast to that of young cats. Cloudiness, tearing, and discharge in the eyes
  • Exercise level: Less activity leads to weight or muscle loss (resulting in a bonier appearance), and arthritis is more frequent. The following behavioral changes have occurred: increased meowing, increased roaming about, higher degree of fear and bewilderment or disorientation

Whenever you’re unclear of the age of your cat, you may always consult with your veterinarian for clarification. Using physical and behavioral characteristics, your veterinarian will be able to provide you with the most accurate age estimate for your cat.

Why is understanding my cat’s age important?

Now that you’ve learned how to properly convert your cat’s age into human years, you might be wondering how long cats actually live. When can I anticipate my cat to reach the end of its life? A cat’s life expectancy is often considered to be greater than that of a dog’s — they may live anywhere between 20 and 25 years. As a matter of fact, according to the Guinness Book of World Records, the “oldest cat ever” lived to be 38 years and 3 days old, which is equivalent to 168 years in human years.

  • It is critical to be aware that they have reached this stage of life so that you can determine how to best care for them.
  • Further, although most dogs reach the age of “seniority” at seven years old, cats are considered “mature” or “middle-aged” from seven to ten years old, and “senior” around eleven years old, according to the American Association of Feline Practitioners (AAFP).
  • In general, assisting your cat in maintaining a good diet and weight, as well as ensuring that they have regular vet check-ups, can help to ensure that they have the greatest possible chance of living a long and healthy life!
  • Remember that your cat deserves the finest care available, regardless of their age – which is why Pumpkin insures cats of all ages!

The bottom line…

Finally, cats age considerably more rapidly during their early years than most people realize — by the age of two, your cat is equivalent to being 24 years old in human years. Fortunately, after your cat reaches the age of two, calculating his or her age in human years is rather straightforward — you simply double the cat’s age in human years by four for each consecutive year. To swiftly assess how old (and smart, of course) your beloved feline actually is, you can always refer to our cat age to human years chart (which you can even print off!)

How Cats Age

Cats age at varying rates, depending on their health and the environment in which they live.

The stages of aging and the characteristics of each stage are outlined in the following table as a general guideline.

There are six stages of aging:

  1. Kittens are a cute little thing (birth until typically 6-7 months of age) When your cat is a kitten, he will go through more physical and mental changes than he will at any other moment in his lifetime. As a result of the rapid pace of life, it is essential to concentrate on the following factors to guarantee that you have a well-balanced, sociable and confident adult cat:
  • Nutrition Kittens have unique nutritional requirements. It is advised that kittens be fed high-quality, nutrient-dense kitten chow in order to help them develop into healthy adults. If a kitten stops eating a food type that they previously loved, it is advised that new textures of food be utilized to make up for it. Socialization It is vital to expose your kitten to a variety of people and settings in order for them to develop into well-balanced adults and establish a sound behavioral foundation. Desensitization to things like vehicles, vet checkups, and handling will save these circumstances from generating substantial stress in the future for your pet. Kittens are known for their rough play, and it is advised that they be adopted in pairs since their rough play might be too much for older cats, dogs, and people to handle. Use of the litterboxKittens should be taught how to use the litterbox.
  • Junior is a young man who has a lot of potential (reproductively mature but still growing, typically until 1-2 years old) Adolescence, sometimes known as the junior stage, may be a difficult period for cats, just as it is for human adolescents. Cats grow to their full height and have learnt everything there is to know about life and how to survive in their surroundings. Many cats in the juvenile stage will go through the following:
  • Wandering Junior cats that are not spayed or neutered have a proclivity to wander around in search of a mate, which may be dangerous. Spaying or neutering a cat as a kitten is ideal, but having your cat spayed or neutered by this age can help prevent him from going away. When the cat has reached full maturity, it is critical to verify that the litterbox is of adequate size and that it is being used appropriately. Litterbox Any concerns with correct litterbox use should be addressed as soon as possible in order to avoid continued problems in the future.
  • No matter whether you’re an adult or a prime (3-6 years old) Cats in their adulthood have developed their core temperament and personality characteristics. They do not necessitate the same amount of care and attention as a kitten. There are certain significant factors for an adult cat, though, including:
  • The way people behave and what they do However, while your cat may not be nearly as energetic at this stage of his life as when he was first adopted, he will still require enrichment in the form of frequent physical activity, mental stimulation, and socializing. Requirements for medical care Adult cats benefit from an annual visit to the veterinarian. To avoid difficulties as they get older, it is essential that they maintain a healthy weight and maintain good oral hygiene.
  • A person who has reached maturity (7-10 years old) Cats at the mature period are the human equivalent of 40-50 years of age, depending on their breed. Mature cats are less energetic than adult cats, and this is especially true for male cats. Because of their physical limitations, they may require specific attention. Annual veterinarian examinations will aid in the detection of arthritis, obesity, and dental problems, which are more frequent in older cats. Seniors are referred to as senior citizens (11-14 years old) Cats in their golden years tend to sleep more, eat less, and be less active than they were when they were younger. Pay particular attention to the following unique considerations:
  • Fully grown-up (7-10 years old) Adult cats are 40-50 years old, which is the human equivalent of 40-50 years in the human life cycle. In comparison to adult cats, mature cats have a tendency to be less energetic. Because to physical limitations, they may require specific considerations. Yearly veterinarian examinations will aid in the detection of arthritis, obesity, and dental problems, which are more frequent in older cats, as well as the prevention of future problems. In their later years, seniors (11-14 years old) Cats in their golden years tend to sleep more, eat less, and be less active than they were when they were younger, according to research. Special concerns should be taken into account, including:
  1. Geriatrics is a medical specialty that deals with the elderly (15 years and beyond) Geriatric cats are prone to have medical problems at some point in their lives. A veterinary examination twice a year is advised at this point in the patient’s development. Preserving your pet’s comfort and health to the greatest extent feasible is of paramount significance. Be prepared to make painful judgments about when it is time to say goodbye during the geriatric period, which can extend for several years. Giving your pet the finest care also entails recognizing when he is in pain and prioritizing his needs above your own in order to alleviate his misery
  2. And

Gerontology is the study of old age and old people (15 years and beyond) Veterinarians must deal with medical complications that arise in aging cats. At this point, veterinary examinations are advised twice a year. Your pet’s comfort and health should be of the utmost importance to you at all times. Be prepared to make painful judgments about when it is time to say goodbye during the geriatric period, which can persist for many years. It also entails being aware of when your pet is suffering and prioritizing his needs above your own in order to alleviate that pain.

If you are unclear about the age of your cat, there are a few ways that you may use to estimate its approximate age.

4 Ways to Tell the Age of Cats:

When it comes to kittens, the usual rule of thumb is that they acquire around a pound of weight every month of their lives until they reach the age of about 6 months. As a result, if a kitten is three months old, it should weigh around three pounds. If it has been a month since it was harvested, it should weigh less than a pound. In the case of a 5 month old kitten, it should weigh around 5 pounds, and so on. However, there are certain limitations to using this method of determining age. For example, a kitten in bad health would most likely not weigh as much as they should be weighing.

A kitten that overeats and grows overweight, on the other hand, may end up weighing far more than they should.

As a result, this is not a surefire method of determining the age of a cat.

2.Check the Teeth Out

When kittens are around 2 weeks old, they begin to develop their first set of teeth. Because they will be replaced by adult teeth, these teeth are referred to as deciduous teeth. They are a set of little, sharp teeth that never appear to be fully developed. A kitten’s deciduous teeth are normally complete by the time it reaches the age of 8 weeks. After that, the deciduous teeth begin to fall out and the permanent teeth begin to grow in. All permanent teeth are normally fully developed by the time a child is 7 or 8 months old.

When a cat reaches old age, its teeth begin to deteriorate.

The presence of tartar accumulation on the teeth, which gives them a yellow tint is also common in this group.

If you are unsure of the type of teeth the cat possesses, you should not rely on the teeth to provide evidence of the cat’s age. In the event that you cannot identify the approximate age of your feline family member using one approach, you can always use another.

3.Look Into the Eyes

When a cat is young, the pupils of its eyes are large and clear. Especially if they get cataracts, which is fairly common in cats, their eyes tend to become hazy and indistinct as they grow older. Consequently, the overall state of the cat’s eyes might serve as an indication of the cat’s age. As with every rule, there are always exceptions, and there are no assurances that this one will give you an accurate estimate of your cat’s age. Images courtesy of cocoparisienne and Pixabay.

4.Take Note of Grooming Habits

Cats are well-known for their grooming skills. When they are at their peak, they take advantage of every chance to clean themselves. Throughout the day, you may see cats licking themselves, scratching themselves, and rolling their backs on the ground to maintain themselves in tip-top form. Cats, on the other hand, may become less attentive to their grooming as they become older, as they did when they were younger. Grooming troubles in senior cats can be caused by a variety of factors, including dental problems, health disorders such as arthritis, and a simple loss of interest.

If everything appears to be in order, but they still do not demonstrate the same level of interest in grooming as they did previously, the likelihood is that they are just growing older, more relaxed, lazier, and less concerned as they age.

Our Final Thoughts

It doesn’t matter how old your cat is as long as they are happy, healthy, and enjoying their life with you and the other members of your family, regardless of their age. The most critical period to determine the age of your cat is when it is a kitten, because kittens require more diet and care until they reach the age of an adult. Additionally, seniors may require additional attention and particular nutrition in order to flourish till the end of their life. If you are ever in doubt, consult with your veterinarian to assess the age of your cat and the physical, mental, nutritional, emotional, and dietary requirements of your feline companion.

How to calculate cat age in human years

It is generally said that one human year is equal to seven cat years. This is not entirely correct. A demonstration that cats age more swiftly than humans is being made in this experiment. They do not, however, age in a proportional manner. When it comes to reaching adulthood, cats mature at a considerably faster rate than people do in the beginning of their lives. Once they reach maturity, the rate of their aging begins to slow. The straight comparison of a cat’s age to its human counterpart is challenging, although the common view is that a cat ages the equivalent of 15 human years in the first year of its existence.

Cats, according to experts, age at a pace of around 4 human years each cat year beyond the age of 2 years.

How to tell how old a cat is if you don’t know when they were born

While it is impossible to know exactly when your cat was born, it is still feasible to estimate their age with a high degree of accuracy.

The condition of your cat’s teeth, coat, muscular tone, and eyes can all provide clues as to how old they are. Using the suggestions provided below, you may work to determine the life stage of your cat and then make an informed guess as to how old your cat is.

How to tell a cat’s age by their teeth

When it comes to identifying the age of a cat, the teeth may be quite informative. Cats have 30 teeth as adults, whereas kittens have 26 baby teeth as they grow (also known as deciduous teeth). Kittens begin to grow their first teeth between the ages of 2 and 4 weeks. Kittens should have all of their deciduous teeth by the time they reach the age of six weeks. The replacement of deciduous teeth with adult teeth occurs between the ages of 4 and 7 months. When attempting to determine a cat’s age, it is a good idea to start by counting their teeth.

When it comes to determining the age of a cat’s teeth, the color of its teeth and the amount of tartar on its teeth may both be helpful.

It is possible to notice tartar accumulation around the base of each tooth after three years.

Dark stains on a cat’s teeth, as well as missing teeth, may indicate that the cat is an elderly cat (one over 11 years old).

What a cat’s coat says about their age

As cats get older, their coats frequently begin to exhibit signs of graying. It is possible that this change may not be evident in cats with light-colored coats, but in cats with dark coats, you will notice the appearance of some grey or white hairs where there were none previously. Older cats may tend to disregard their regular grooming habits, resulting in a coat that seems dirtier or duller than it would otherwise. It is not unusual for the texture of a cat’s hair to alter as the cat grows older.

If you detect any unexpected changes in your pet, don’t hesitate to call your veterinarian.

Muscle tone – another cat aging factor

Another indicator of your cat’s age is the tone of his or her muscles. Kittens are often quite thin and have not yet developed a significant amount of muscular mass. Adult cats who are in excellent health usually have strong muscular tone. Protruding bones and a straight spine are desirable characteristics in a person’s posture. Once a cat reaches his or her senior years, it is not uncommon for him or her to begin losing muscle. You may notice that the shoulder blades or hip bones of your senior cat are protruding more than they were previously.

It goes without saying that this results in a loss of muscular definition.

Cats with insufficient nutrition or health conditions such as renal disease may have difficulty maintaining their body weight and muscular tone. In the event you see a rapid and considerable loss of muscle mass in your aged cat, consult your veterinarian immediately.

Cat’s eyes and the aging process

A young cat’s eyes are clear and brilliant, which indicates that it is in its prime. If your cat is becoming older, it may acquire cataracts or glaucoma, which may cause discoloration or cloudiness in their eyes. Senior cats may have more discharge from their eyes than a kitten or an adult cat. Sometimes the form of a cat’s irises will alter as well, becoming jagged around the edges rather than smooth as a result of this.

How do cats age?

In accordance with the data in the chart above, cats experience the greatest number of age-related changes throughout the first two years of their existence. Cats are considered to be similar in age to a 15-year-old person by the end of the first year. An adult cat passes through this stage from being a newborn kitten with closed eyelids and no teeth to becoming a young adult cat who has attained sexual maturity. By the time they reach the age of two, cats are reported to have aged around nine human years, making them the equal of a 24-year-old person by the time they reach the age of two.

By this point, they have gained significant muscular mass and are beginning to take on the characteristics of an adult.

Cats are called senior citizens when they reach the age of around 11 years.

A reduction in physique, graying fur, and changes in the appearance of their eyes, teeth, and coat are all symptoms that your cat is beginning to exhibit signs of age around this time.

Signs of a senior cat

As with humans, there are several telltale markers of seniority in cats that are similar to those in people. Despite the fact that senior cats are frequently healthy and full of life, they may begin to slow down a little as they become older. Since your cat approaches senior status, it’s crucial to keep an eye out for any changes, as severe alterations might be an indication of major health problems. Cats in their senior years may display the following behaviors:

  • Increased stiffness and reduced mobility
  • Cloudy eyes
  • A dull coat
  • Excessive eye discharge
  • Weight loss and lack of muscular tone
  • Need to urinate often
  • Confusion or disorientation are common.

Senior cats may potentially suffer from dementia in addition to physical deterioration. Frequent meowing, confusion, and excessive napping are some of the indicators of feline dementia that can be observed. Senior cats might still have many good years ahead of them, so don’t be disappointed or distressed if you see that your cat is beginning to sluggishly age. Simple lifestyle modifications, such as feeding your senior cat specially made food, can help them make the most of their golden years.

How long can cats live? How long do cats live on average?

Cats have a life expectancy of 16 to 18 years on average, however some cats may live much longer. According to the Cornell Feline Health Center, many cats survive into their twenties or twenties and a half. Particular cat breeds are noted for having remarkably lengthy life spans, while others are known for being more prone to certain health conditions than others. It has been said that the life expectancy of bothSiamese and Savannah cats can go as high as twenty years. Ragdoll and Persian cats, on the other hand, are both prone to Polycystic Kidney Disease (PKD) (PKD).

This is partly due to the fact that indoor cats are exposed to fewer dangers than cats who live outside.

These suggestions can help you keep your outdoor cats safe.

Although even indoor cats that are exceedingly well cared for might become ill at any time, certain breeds that are especially prone to specific health problems may never be impacted by them.

It is possible to enhance your cat’s life expectancy by feeding them a well-balanced food and ensuring that they maintain a healthy body weight. This will also keep them nimble and active long into old age.
