How To Tell If Your Cat Has A Fever

Signs That Your Cat Has a Fever & What To Do

It is possible that your cat is suffering from a fever as a result of an underlying health condition that requires immediate attention. Today, our Greensboro veterinarians will discuss some of the causes and symptoms of feline fevers, as well as what to do if your cat is suffering from a fever.

How To Take Your Cat’s Temperature

Cats have a normal body temperature that ranges between 100.4o and 102.5o Fahrenheit on average. Having a fever in cats is defined as having a body temperature more than 102.5o F. If your cat’s fever rises above 106 degrees Fahrenheit, he or she is at great danger of suffering serious organ damage. Taking your cat’s temperature is a very simple procedure. Simply use a digital thermometer pointed at your cat’s ear, or a pediatric rectal thermometer for a more precise reading, to check his temperature.

If the thermometer malfunctions, it might be extremely dangerous to your cat’s health.

Petroleum jelly should be applied to the thermometer to make it more lubricated before inserting it.

It is possible that you will want assistance in calmly restraining your cat while you insert the thermometer.

If you suspect that your cat may be suffering from a fever but are hesitant to take their temperature, contact your veterinarian immediately to schedule an appointment.

Causes of Fever in Cats

Fevers in cats are most commonly caused by the immune system of the cat being stimulated by situations such as: Outdoor cats are at the greatest risk of contracting infections that can cause fever, such as the following:

  • Cytauxzoonosis is a tick-borne disease that affects cats and is more widely known as bobcat fever in humans. Haemobartonellosis is a parasitic bacterial blood illness that is most commonly encountered in cats. Ehrlichiosis is a tick-borne disease that may infect cats as well as humans. Bartonellosis (also known as cat scratch fever) is a kind of infection caused by a cat scratching itself. Toxoplasmosis – A parasite illness that causes fever in cats
  • It is also known as toxoplasmosis.

Signs That Your Cat May Have a Fever

If your cat is suffering from a fever, he or she may exhibit one or more of the following symptoms, depending on the underlying cause of the illness:

  • Shivering, rapid heart rate, and decreased activity are all symptoms of hypothyroidism.
  • Drinking less, being dehydrated, grooming poorly, vomiting, and diarrhea are all symptoms.

What To Do If Your Cat Has a Fever

Never feed your cat human drugs unless you have obtained the express permission of your veterinarian. The use of several common human drugs, such as acetaminophen, can be exceedingly hazardous to cats’ health. Provide your cat with easy access to fresh, clean water, as well as a comfortable spot to rest, to ensure that they remain hydrated. If your cat’s fever lasts more than 24 hours or rises beyond 106 degrees Fahrenheit, contact your veterinarian immediately to schedule an emergency appointment or take your cat to an emergency animal hospital.

In certain situations, even after a thorough veterinarian examination, the reason of your cat’s fever may remain a mystery, and your cat may be diagnosed with a fever of undetermined origin (FUO).

Fevers in Cats

How can you determine if your cat is suffering from a fever? In humans, a warm forehead kiss may provide a hint as to what is happening. However, unlike what many people assume, you cannot detect whether your cat has a fever by feeling for a warm, dry nose. When dealing with either a person or a cat, the only way to be certain is to take its temperature. A typical temperature in the United States is between 100.4o and 102.5o Fahrenheit. When the temperature rises above 102.5 degrees Fahrenheit, cats get a fever.

If your cat is running a high temperature, call your veterinarian straight immediately.

Causes of a Fever in Cats

Which signs indicate that your cat may have a fever? It is possible that a warm forehead kiss will provide a clue in human relationships. However, contrary to popular belief, you cannot detect if your cat is suffering from a fever by feeling for a warm, dry nose. In order to be certain, you must take the animal’s temperature (whether it is a person or a cat). Typically, the temperature varies between 100.4o and 102.5o Fahrenheit. When the temperature rises beyond 102.5o F, a fever in cats develops.

If your cat develops a high temperature, call your veterinarian straight once to get him checked out.

  • An infection caused by bacteria, viruses, or fungi
  • There’s a tumor there. Injury resulting from a traumatic event
  • Medications of a certain nature
  • Lupus and other autoimmune diseases

A fever that lasts for more than a few days and has no evident cause is referred to as a fever of unknown origin (FUO).

Signs of a Fever in Cats

Fever-inducing diseases in cats can also manifest themselves in the form of certain telltale behaviors. Cats are able to preserve the energy required to develop a fever because of these characteristics, which originated in wild animals to aid them in their survival of sickness. Frequent fevers help the body fight sickness by activating the immune system and inhibiting the development of germs and viruses. Keep an eye out for these indicators of a fever:

  • Appetite loss
  • Depression
  • A lack of energy or activity
  • And so on. Less drinking
  • Concealment
  • Reduced grooming
  • Shivering or fast breathing

Besides these general indicators of disease, your cat may also exhibit particular signs of illness such as sneezing, vomit, or diarrhea.


A temperature reading is the only method to determine whether or not your cat has a fever with absolute certainty. When it comes to taking a cat’s temperature, a pediatric rectal thermometer is the most precise way. Using a digital thermometer is more secure than using a traditional glass thermometer.

Dropping it will not cause it to break, and it will send you a signal when it is time to check the reading. You can get one from your veterinarian or from a drugstore. To begin, gather all of the materials you’ll need, including the following:

  • The thermometer, to be precise. A lubricant for the thermometer, such as petroleum jelly, is recommended. To clean the thermometer, use rubbing alcohol and a paper towel. A treat for the cat

Secondly, gently shake a glass thermometer such that the mercury is below the 96o mark. Hold it up to the light and spin it to make sure it’s not broken. You must first switch on a digital thermometer before using it. Coat the thermometer’s tip with oil to prevent sticking. 4. Have a friend or family member confine your cat so that the hind end is facing you. Alternatively, if you are alone, cradle your cat’s body against your chest with one arm. Then, using a gentle lifting motion, put the thermometer into the anus.

  • As soon as this has occurred, insert the thermometer approximately one inch into the rectum without forcing it.
  • When you hear the beep, remove the digital thermometer from your pocket.
  • 7.
  • Holding a glass thermometer up to the light and spinning it will allow you to determine the temperature.
  • If your cat has not been vomiting, reward him or her with a treat.

Cat Fever Care

Cats who have been showing indications of a fever for more than 24 hours or who have a temperature more than 104o F at any time should be taken to the veterinarian. The veterinarian may do tests to discover the source of the fever and then take actions to alleviate the underlying condition that is causing it. If, for example, a bacterial infection is the root of the problem, antibiotics may be required. Hydration is managed through the injection of intravenous or subcutaneous fluids in cases of moderate or severe dehydration.

Fever drugs such as acetaminophen, which is hazardous to cats, are not recommended.

How to Tell if Your Cat has a Fever

When your cat is feeling under the weather, she can’t exactly beg for a pain pill or an ice pack to make her feel better, so you may find yourself thinking, “Can I give my cat something to help her feel better?” “Is my cat suffering from a fever? And, more importantly, how can I determine whether she does?” Learn how to recognize the signs and symptoms of your cat’s fever, as well as the reasons and treatments available.


When people have a fever, there are some symptoms that are obvious in cats as well. These symptoms include lack of appetite, weakness or lethargy, shivering, dehydration, and ears that are warm to the touch, among others. According to the sickness that is producing your feline friend’s high fever, your cat may also display other symptoms unique to the illness that is generating the high temperature, such as increased respiratory rate and/or fast heart rate. Taking your cat’s temperature is the most conclusive technique to identify if she is suffering from a fever.

  • A temperature that is higher than this range may suggest the presence of a fever.
  • It normally requires two individuals to take your cat’s temperature: one to control the cat and the other to place the thermometer into the mouth.” Always lubricate the thermometer with petroleum jelly and keep it in for at least two minutes to provide the most accurate reading.
  • A mercury thermometer should never be used on your cat because if the thermometer breaks, it can be extremely dangerous to your cat’s health and life.
  • You should call your veterinarian as soon as possible if you are uncomfortable checking your cat’s temperature at home.

It is also crucial to bring in your cat’s vaccination record in order to assist your veterinarian in obtaining the best record possible of any other illnesses that your cat may have contracted but for which he or she has not been vaccinated in order to narrow down the source of your cat’s fever.


Your veterinarian will evaluate whether or not more testing is necessary to discover the source of your cat’s fever (or pyrexia, as it is known in medical terminology). It will be extremely beneficial to know the cat’s medical history. Carry evidence of your cat’s history, including a list of prescriptions, if you have to take her to an after-hours veterinary clinic rather than her normal doctor. Cats are known to respond negatively to particular medications, so it is important to bring paperwork.

Other factors include problems with the immune system or inflammation, exposure to chemicals, a disorder, or a medical condition.


Typically, antibiotics are used to treat feline fevers, which are also managed with rest and fluids. Getting your cat to take medicine, like getting your cat to take his temperature, may not be simple, but it is critical to his health. If your cat spits out her pill or refuses to eat the cat food in which you’ve concealed it, VCA Hospitals has some excellent advice on how to give medicines to a feisty cat. In order to provide comfort and security, one technique is to cover her in a towel. It’s a fantastic idea to hire a helper to aid you with this difficult task.

It’s difficult to see your pet suffer from a fever, but in addition to following your veterinarian’s recommendations for medical care, there are certain things you can do to spot an infection early and prevent it from progressing further.

Do not forget to shower her with kisses, embraces, and other affection.

How to Check Your Cat’s Temperature Without a Thermometer

Image courtesy of Vladdeep/iStock/Getty Images. Unlike in the past, your cat hasn’t been a tornado of energy, racing across the room to chase after his favorite toys. The rattling of his food bag is ineffective in getting him to hurry to his plate. In the event that your cat appears to be unwell, you may want to check to determine whether he is experiencing symptoms of a fever. The most accurate method of determining a cat’s temperature is to use a rectal thermometer on the cat. Ear thermometers built exclusively for cats can also provide a reasonably accurate readout of their body temperature.

However, if you don’t have one of these or aren’t certain that your cat will allow you to check his temperature, there are alternative ways to determine whether or not he is suffering from a fever.

Too hot?

The body temperature of a healthy cat should range between 100.4 and 102.5 degrees Fahrenheit. If it’s higher than that, it’s likely that he’s sick and has a fever of some kind on him. Lethargy, loss of appetite, reduced grooming, and shaking are all symptoms of having a fever, according to the American Academy of Pediatrics. When a cat’s immune system responds to a sickness or infection, the same as in people, the cat will develop a fever. Bacteria, viruses, and fungi all have the potential to cause illness in your cat.

It will be impossible to determine the exact level of a fever without a thermometer, but a trip to the veterinarian is recommended if you notice any additional indicators of fever, if your cat is sick for more than a couple of days, or if your cat refuses to eat or drink.

Check the nose

Normally, cats’ noses are chilly and wet, which you may notice if your cat nudges you with her nose to get up and play with her or feed her at three o’clock in the morning. When ill cats have a fever, though, their noses are frequently dry and warm. However, if they are dehydrated, their nostrils might get dry as a result. Try gently pulling part of the hair and skin on your cat’s back to see if it helps. Instead of being feverish, she may be dehydrated if the bandage doesn’t snap back into place right away.

Hot ears

When your cat is healthy, put a finger on the inside of her ear on the inside side of her ear. It will have a pleasant warmth to it. It will feel substantially hotter if she has a fever, comparable to when you feel someone’s forehead to determine whether it is hot when a fever is suspected.

Warm back

If your cat has a fever, his back may also feel warmer to the touch than usual, similar to how his ears may feel. Make sure your cat hasn’t been snoozing in his favorite sunny location or right in front of a heat vent before you do anything else.

Fast breathing and shivering

It is possible for cats to develop a fever and begin to breathe more rapidly, orpant. Shivering in animals can be an indication of fever, just as it is in people.

What to expect at the vet

You should take your cat to the veterinarian if you see any of these indicators and he is not acting normally. The vet will perform a complete examination and take an accurate temperature reading. Your cat’s medical history will be reviewed by your veterinarian, including any contact with sick animals, allergies, vaccines, and recent illnesses. A full blood count and biochemistry panel, as well as a urinalysis, will most likely be ordered by the veterinarian. If the origin of the sickness is unclear, scans such as ultrasonography, magnetic resonance imaging (MRI), or computed tomography (CT) may be conducted to gain a clearer look at what’s going on within the body.

In certain cases, an injection of a long-lasting antibiotic is administered, and antibiotic pills must be administered to your cat once or twice a day as needed.

Prior to making any dietary, pharmaceutical, or physical activity changes for your pet, consult with your veterinarian. This material is not intended to be a substitute for the advice of a veterinarian.

Fever of Unknown Origin in Cats

Fever is a medical word that refers to an abnormally high body temperature. It is usual for cats to have a body temperature between 100.5 degrees Fahrenheit and 102.5 degrees Fahrenheit (38.1 degrees Celsius and 39.2 degrees Celsius). Fever of unknown origin (FUO) is defined as a fever that persists for more than a few days and has no evident underlying cause based on the patient’s history and physical examination.

What causes a fever?

Fiebrile conditions are caused by the presence of apyrogen (a fever-producing substance). The pyrogen can be either endogenous (made by the body) or exogenous (generated outside of the body) (from the outside). The release of chemicals from white blood cells (leukocytes) as a result of this pyrogen includes interleukin-1, interleukin-6, and tumor necrosis factor. These compounds, in turn, reset the body’s “thermostat,” which is a temperature-regulatory area situated in the hypothalamus and responsible for controlling body temperature (located in the brain).

If this is a natural process, why is it a problem?

In the body, a fever is advantageous because it inhibits the capacity of viruses and bacteria to multiply and increases the immune system’s reaction to foreign invaders. In contrast, if the patient’s body temperature is elevated beyond 105°F (40.5°C) for more than a day or two, he or she becomes lethargic and anorexic, and can get dehydrated very quickly. Cerebral edema (swelling of the brain and surrounding tissues), bone marrow suppression, and clotting abnormalities (disseminated intravascular coagulation, or DIC) may develop if the temperature remains over 106°F (41.1°C).

For example, greater metabolic needs to sustain the higher temperature result in increased fluid and calorie requirements as well as increased breakdown of muscular tissues..

What are the clinical signs of fever of unknown origin?

In addition to being sluggish and unwilling to move, most cats suffering with fever exhibit a loss of appetite, elevated heart and respiratory rates, and are dehydrated. It’s also possible that they’re shivering or stiffening up. The following clinical indicators are present in patients suffering from a fever of unknown origin, yet there is no evident explanation for them.

How is FUO diagnosed?

If your cat develops a fever, your veterinarian will do a complete physical examination, paying close attention to any bite wounds, lacerations, punctures, or other symptoms of trauma that your cat may have suffered. A complete blood cell count (CBC), a serum biochemistry panel, feline leukemia virus (FeLV) and feline immunodeficiency virus (FIV) testing, and a urinalysis are all routine diagnostic blood tests for cats. Urine cultures are frequently conducted in order to determine whether or not a urinary tract infection is present.

A definitive diagnosis may also need the use of diagnostic imaging (such as X-rays or ultrasound) or cytology (the examination of the cell types aspirated from swellings or masses).

What causes FUO?

As the name implies, this is a fever that cannot be traced back to a specific cause. The majority of instances of fever in cats are caused by a viral infection, such as FeLV, FIV, FIP, feline panleukopenia virus, herpesvirus, or calicivirus, which are all contagious. Many viral infections will fluctuate in intensity before finally resolving. For example, it is normal for a cat suffering from a viral illness to appear perfectly well for a week or two before experiencing a recurrence a few days later.

Yersinia, Mycobacteria, Nocardia, Actinomyces, and Brucella are among the bacteria that can cause unusual bacterial illnesses as a result of bite wounds.

A fever may also develop as a result of inflammation induced by physical trauma, lymphoma and other malignancies, or as a result of a systemic fungal infection, which is less frequent.

You should advise your veterinarian of any recent travel, any exposure to unknown or diseased animals, supplements or drugs that you are giving, and any other information that you believe may be relevant.

How is FUO treated?

It is critical to recognize that the diagnostic work-up for FUO can be time-consuming and complicated. It is important that your veterinarian determine the particular reason of your pet’s fever so that it may be treated appropriately and that a proper prognosis can be given. While it is not always possible to acquire an accurate diagnosis, it is acceptable to assume that FUO is the cause of the symptoms and to begin therapy based on the information available. Bacterial infections are frequently treated with antibiotics, and antibiotics are frequently administered to prevent bacterial infections from arising as a secondary concern.

Pet owners are advised to avoid administering these medications to their cats unless they have received written permission from a veterinarian.

A non-steroidal anti-inflammatory medicine (NSAID) is frequently used to treat fever in humans (NSAID).

acetylsalicylic acid (Aspirin®) and acetaminophen (Tylenol®) are both very hazardous to cats and should never be given to them by their owners unless specifically instructed to do so by a veterinarian.

What is the prognosis for a cat diagnosed with FUO?

When the underlying cause of a problem is identified, it is possible to provide an accurate prognosis. Because the specific etiology of FUO is unclear, it is impossible to provide a reliable prognosis in this situation. The majority of cats react well to basic supportive care, which includes keeping them warm and dry, providing plenty of water and sustenance, and delivering medicines when necessary or recommended. Cats suffering from a prolonged fever or a fever that comes and goes must be subjected to a comprehensive examination so that the source of the fever may be identified and treated before any permanent harm is caused.

In situations when this pattern is repeated more than once, it is critical that a full diagnostic work-up is performed as soon as possible.

Fever in Cats – Signs, Causes, Diagnosis, Treatment, Recovery, Management, Cost

Because a fever is a symptom rather than a medical illness, it is vital to determine the source of the fever in order to treat it effectively. If you have a high fever or a fever that lasts longer than one or two days, you should seek medical assistance. If your cat has a fever, do not attempt to treat it yourself since many drugs are toxic to cats and the underlying reason of the fever might be life-threatening. Infections, diseases, cancer, and a variety of other ailments are frequently accompanied by fever.

Symptoms of Fever in Cats

Feline fever is characterized by a body temperature more than 103 degrees Fahrenheit as the major symptom.. Flushing and tiredness are two of the most commonly seen signs and symptoms. In the case of high temperatures or a persistent fever, more serious symptoms may manifest themselves. Depending on the underlying condition that is producing the fever, the cat may exhibit a range of additional indications as well. Among the warning signs are:

  • Symptoms include elevated body temperature, dry skin and mouth, dehydration, flushing and reddening of the skin. Appetite loss, weakness, and lethargy are all symptoms of menopause. The heart beats quickly
  • Excessive panting or rapid breathing

The following are severe warning signs:

Causes of Fever in Cats

The presence of a fever in cats or other companion animals can be caused by a range of medical conditions. Fever is a typical symptom of a wide range of illnesses and infections. It is possible that the reason of the fever will not be discovered in some circumstances. Fever can be caused by a variety of factors, including:

  • Bacterial infections
  • Viral infections
  • Fungal infections
  • A variety of parasites
  • Tumors or some malignancies
  • Internal injuries
  • Certain drugs
  • And more. Contamination with poisons or toxins
  • Autoimmune illness, metabolic problems, endocrine disorders, and environmental factors all have a role.

Diagnosis of Fever in Cats

Taking the cat’s temperature can be used to determine whether or not the cat has fever. This is usually performed by using a thermometer in a straight line. The presence or absence of a fever will be determined by the animal’s body temperature. A fever will be detected and further diagnostic procedures will be performed to discover the source of it. A fever is often considered to be a symptom of an illness, disease, or other condition. Prepare to talk about your pet’s medical history as well as any indicators you’ve noticed in your pet.

It may be necessary to do a comprehensive blood panel as well as tests for other viral or inflammatory illnesses in order to establish why the cat’s body temperature is raised.

Once a comprehensive diagnostic effort has been undertaken and no definitive cause of the fever has been identified, the patient will be diagnosed with a fever of undetermined origin. Top

Treatment of Fever in Cats

There is nothing that can be done to treat a fever until the source of the fever has been identified. Low-grade fevers may not require the veterinarian to make any attempts to bring the temperature down, since it is natural for the body to elevate its temperature in order to help the immune system in battling illnesses. When treating a fever, the major focus will be on keeping the patient hydrated and keeping the temperature down. Additional therapies may differ depending on the underlying ailment.

The following are examples of common treatments:

  • Fluids administered intravenously (IV) or subcutaneously (SQ): If the cat is displaying indications of dehydration, fluid treatment is required. IV and SQ fluids help to battle dehydration while also providing nutrients to help with a lack of appetite. They may also be helpful in slightly reducing the core body temperature. The likelihood of negative effects from this common medication is quite low
  • Pain and inflammation drugs, such as nonsteroidal anti-inflammatories (NSAIDs) that are suitable for cats, can be beneficial in lowering a cat’s temperature. Never attempt to provide this sort of medication to your cat at home unless instructed to do so by a veterinarian, as administering the incorrect prescription can be lethal to cats. The right drugs and dose for your pet’s size and needs will be determined by your veterinarian in order to limit the possibility of major problems occurring. Antibiotics: Because infections are a prevalent cause of fevers, antibiotics are a typical therapy for these illnesses. Due to the fact that this sort of medication is designed to remove bacterial infections, your veterinarian will not prescribe it until the infection has been diagnosed as the source of the problem. Corticosteroids are a type of medication that is used to treat inflammation, which is a major cause of fever in children. It can be used to treat a variety of illnesses that produce fevers, and it is frequently used in the treatment of fevers of unknown etiology. Surgeons may be required in situations of severe illness, malignancies, or certain parasites in order to remove the source of the infection or tumor. In order to establish if surgery is the best plan of action for your cat’s rehabilitation, your veterinarian will need to assess whether or not surgery is necessary.

Recovery of Fever in Cats

The prognosis for recovering from a fever is determined by the underlying reason. Even in the event of mild diseases or illnesses, as well as in the case of certain fevers of unknown cause, therapy will lower the fever and the cat’s prognosis will be excellent. Depending on how bad the underlying problem is, your pet’s rehabilitation may require significantly more time and medical attention. When your cat comes home, continue to keep a close eye on him or her for signs of illness such as fever or other symptoms.

  1. Please be sure to follow all of the recommendations provided by your veterinarian, including completing the whole course of meds even if symptoms appear to have improved or the fever has subsided completely.
  2. Keeping your pet’s caloric intake at an adequate level when they are suffering from a fever may necessitate certain dietary modifications to aid in their recovery, such as healthy meals or even high-calorie beverages.
  3. Pet health insurance can help you prevent expensive veterinary bills in the future.

How to Tell If Your Cat Has a Fever

Do you know what the usual temperature for cats is and how to identify if your cat has a fever? Do you know what the normal temperature for dogs is? Many cat owners are unclear about what to do. Because cats, unlike humans, are unable to feel their foreheads for signs of increased heat, it can be difficult to determine whether or not they are suffering from a fever. Cats, on the other hand, can provide us with hints. Maintaining awareness of your cat’s usual behavior will assist you in recognizing when something is wrong.

Common Cat Fever Symptoms

Is your cat running a fever? Do you know what a typical cat’s temperature is and how to determine whether or not your cat is sick? Many cat parents are uncertain about what to do with their feline companion. It might be difficult to tell whether your cat has a fever since, unlike humans, you cannot feel their foreheads to check for excess warmth. We can learn a lot about cats by watching them and listening to their calls. Being aware of your cat’s usual behavior will assist you in recognizing when something is wrong with him.

Furthermore, because cats are notorious for concealing their symptoms when they are sick, keeping a constant eye on them is essential for determining whether or not they are suffering from fevers in the first place.

  • Dehydration, panting, rapid pulse, weakness, behavioral abnormalities, and decreased grooming are all symptoms of dehydration.

Popular culture may persuade us to assume that a healthy cat has a cold, wet nose, leading us to believe that a dry, warm nose indicates the presence of a fever in the cat. This, on the other hand, is not correct. Doctor Wolfe notes that sometimes clients remark to him that their cat’s nose was warm or that the cat ‘felt warm or hot,’ but that this is not a reliable predictor of fever in cats. “The usual temperature range for a cat is 101.0-102.9 degrees Fahrenheit. I consider temperatures of 103.0 and above to be a ‘fever.’ In addition, a cat’s temperature may be increased during the summer and in stressful situations (such as veterinarian appointments).” In Dr.

Only a properly calibrated thermometer can provide an accurate diagnosis of a fever.

Wolfe warns against diagnosing a cat’s fever without first evaluating it for itself.

How to Take Your Cat’s Temperature

Allowing a professional to handle the problem is the quickest and most likely most effective method of taking a cat’s temperature. Cats, on the other hand, are typically not fond of it and may grumble or struggle against it. When there is cause for worry, a reputable veterinarian practice can get a reliable reading of a cat’s temperature. The correct equipment is required if you want to attempt to take the temperature of your cat at home. Besides a rectal digital thermometer and Vaseline, Dr.

“Apply a generous amount of Vaseline to the thermometer and put the tip into the cat’s anus.

If your cat’s temperature is elevated to the point of becoming feverish, contact your veterinarian for guidance on what to do next.

Reasons a Cat Has a Fever

Knowing how to detect whether your cat is suffering from a fever, it’s time to learn more about what a fever signifies for his or her overall health. Fever in our feline pals might imply one of the following things:

  • Infections, such as bacterial, viral, or fungal infections
  • Injury
  • Disease
  • Tumors
  • Poisoning
  • The environment
  • Parasites
  • And a reaction to treatment are all possibilities.

Do feverish symptoms in your cat portend the end of the world for him? Because this is not always the case, don’t be alarmed if your cat’s temperature is a bit elevated. Just like it does in humans, a fever can sometimes resolve itself on its own. As a result, notes Jo Ann Morrison, DVM, DACVIM, senior manager of medical quality improvement for Banfield Pet Hospital in Portland, Oregon, “fever in cats can be a normal immunological response to pathogens, such as an infection,” and, as a result, “not every fever in cats has to be ‘treated.'” In the event that you suspect your cat is suffering from a fever, call your veterinarian immediately to describe what you are experiencing and choose the best course of action.” The normal body temperature of a cat might be difficult to determine, and it is always best to be safe than sorry in this situation.

If the symptoms persist, contact your veterinarian.

It could also be a good idea to schedule an appointment so that your veterinarian can examine your cat in person in order to provide an accurate diagnosis. Written by Elisa Jordan Image courtesy of Thinkstock/Anna Dudko Hemera for the featured image.

Taking a Cat’s Temperature Doesn’t Have to Be Difficult

To determine whether or not your cat has a fever, it is necessary to measure his or her body temperature. Provided that the cat isn’t putting up any resistance, the entire procedure should just take a few minutes. Most cats have a typical body temperature that ranges between 100.5 and 102.5 degrees Fahrenheit. Depending on the severity of the other symptoms, higher temperatures may necessitate a visit to the veterinarian.

Before You Begin

Keep an eye out for specific actions in your cat that may indicate that he or she has a fever. These enable the cat to preserve energy, allowing it to devote more of its resources to battling the ailment that caused the fever. Frequent fevers help the body fight sickness by activating the immune system and inhibiting the development of germs and viruses. Even while fevers can sometimes be beneficial in the battle against sickness, a fever of more than 106 degrees Fahrenheit might result in organ damage.

Keep an eye out for the following symptoms of a fever:

  • The following symptoms may occur: loss of appetite, depression, lack of energy or activity, reduced drinking, reduced grooming, shivering or fast breathing, sneezing, vomiting, diarrhea.

You can take your cat’s temperature either rectally or via its ear, however rectal temps are more precise than ear temperature readings. Using a rectal thermometer, you can determine how hot the cat’s body temperature is at any given time. Digital thermometers provide a reading significantly faster than traditional thermometers, allowing the operation to be completed in less time. As a precaution, store the thermometer in a different location so that it is only used on the cat.

What You Need

To take a rectal temperature, you’ll need the following materials:

  • A human rectal thermometer, Vaseline or KY Jelly for lubrication, a timer with a second hand, and a towel are all required.

Prepare the Thermometer, Then the Cat

Turn on the thermometer and set it to zero, and then lubricate the thermometer with Vaseline or KY Jelly to prevent it from sticking. Place the cat on the counter and securely hold it in place with your arm and forearm. Its face should be resting in the crook of your elbow, and its tail end should be resting against the opposite arm. If required, cover the cat in a towel so that its buttocks are protruding from the towel.

Insert the Thermometer

One hand should be used to lift the cat’s tail, while the other hand should be used to carefully and steadily enter the thermometer into the cat’s anus to a depth of 1/2 to 1 inch, depending on the cat. Initially, you will notice the sphincter muscle tightening, followed by its relaxation. Continue to hold the thermometer in place for two minutes (or until the digital thermometer beeps if it is digital) while speaking in a calming tone to the cat.

Remove, Record, and Wash

Remove the thermometer from the room. Make a note of the temperature, as well as the date and time. Warm water and disinfectant soap should be used to thoroughly clean the thermometer, which should then be stored apart from any thermometers used for people. Wash your hands well, as well as the sink where you rinsed the thermometer, because cat feces can contain a variety of hazardous germs.

Taking Your Cat’s Temperature via Its Ear

Although taking the cat’s temperature through its ear is less likely to result in resistance, the technique can be more challenging. Ear thermometers must be positioned in the proper location in order to provide an accurate reading. While your cat may accept this procedure more than having its temperature taken rectally, the animal may attempt to flee if you approach it too closely. If this occurs, take the cat by the scruff of the neck, which will typically (if only momentarily) calm the majority of cats.

Hold it horizontally while maintaining control of the cat’s head. As soon as the thermometer beeps to indicate that it has taken a reading, release your cat and record the temperature. Remove the thermometer from its case and thoroughly clean it.

Preventing Problems With Your Cat During Readings

In the event that you are having difficulty getting an accurate read, having a second (or third) set of hands might be beneficial. If one person is capable of holding the cat, the other is typically capable of holding the thermometer. A temperature of 105 degrees Fahrenheit is considered serious, and your cat should be checked by a veterinarian as soon as possible after acquiring this temperature. If the temperature rises beyond 103 degrees Fahrenheit, you should consult your veterinarian for guidance.


  • Most cats will resist having their temperature taken, and your cat may bite or scratch you if you attempt to take their temperature. Dress in long sleeves and consider wearing protective gloves if necessary. If at all feasible, have a second person who is familiar with the cat assist you by holding, talking to, and caressing the cat while you take its temperature. Allow your cat to leave the room after you’ve finished reading. It’s possible that it will pout for a bit. After the procedure, give your cat a treat or a modest snack (as long as it is not displaying indications of a digestive disease) to express your appreciation.

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.

Fever – is it serious? – Bishops Stortford Vets

When you place your hand on your cat’s body, it will often feel warm, especially if you are touching a piece of naked skin. Cats have a greater body temperature than humans, which accounts for this difference in body temperature. Despite the fact that body temperature is kept within a very small range (between 38.1°C / 100.5°F and 39.2°C / 102.2°F), it does vary significantly during the day, with the lowest temperatures being recorded in the morning and the highest values reported in the evening.

  • The cat’s body temperature remains constant even when the cat is subjected to drastic variations in the surrounding environment’s temperature.
  • In response to an increase in body temperature, blood flow through the skin rises, resulting in increased heat loss from blood circulating near the surface of the animal.
  • The act of shivering happens when the environment is chilly (since muscular activity boosts heat generation), cats curl up in a ball, and their fur coat becomes erect to trap warm air against their skin.
  • In some illnesses, brief fever’spikes’ (also known as “spikes”) occur (where the temperature is suddenly raised for a short period of time only to drop to normal and then rise again later).
  • An infected cat is typically sad and may refuse to eat, but a moderate fever that lasts for a short period of time does not cause any permanent damage to the body.
  • The use of fans and soaking the coat in cool water may be beneficial, but veterinarian assistance should be sought quickly.
  • It is believed that fever is generated by the activity of ‘pyrogens,’ which are chemicals that alter the level at which the body’s temperature is kept constant.
  • Microorganisms such as bacteria and viruses, poisons, certain medications, and naturally occurring compounds are all examples of pyrogens, which are molecules generated by the body in reaction to inflammation.
  • Increased body temperature may help the cat cope with the infection more effectively since bacteria do not multiply as fast at higher temperatures as they do at lower temperatures.
  • If you have a suspicion that your cat is suffering from a fever, you can take their temperature to be sure.
  • If your cat is very calm, he or she may allow you to take their temperature; if not, you should contact your veterinarian to perform this task on your behalf.

If the thermometer is mistakenly put into faeces in the rectum, a falsely low temperature reading may be obtained; if you suspect this may have occurred, check the temperature again after your cat has just passed a motion to be sure.

  • Turn on the thermometer (which is often accomplished by pushing a button on the side)
  • Dip the end of the thermometer into vasoline or a similar lubricant and read the temperature. Lifting your cat’s tail carefully and slowly inserting the thermometer into the rectum will result in a more accurate reading. Maintain the thermometer’s position until a consistent temperature reading is obtained (most digital thermometers will automatically ‘bleep’ when a temperature measurement has been captured)
  • Remove the thermometer and take note of the temperature displayed in the little window that has been created
  • Before storing the thermometer, make sure it is turned off and clean. Make a note of the time and date that the temperature was taken

The great majority of feline fevers are caused by infections of some type, according to the American Feline Fever Association (usually an abscess caused by a bite from another cat). The majority of the time, the body temperature returns to normal on its own or with the assistance of drugs to treat the illness. In other circumstances, fever persists despite routine testing, and no evident reason of the elevated temperature can be identified – in these cases, the disease is referred to as ‘Fever of Unknown Origin,’ or FUO for short.

  • Depending on whether or not your cat’s temperature remains elevated after a few days of therapy, your veterinarian may decide to do additional tests to try to determine the source of the problem.
  • To confirm or rule out a certain diagnosis, it may be necessary to perform some tests several times over.
  • It may, however, be possible to attempt drugs to lower the temperature if certain conditions have been deleted from the checklist if certain conditions have been excluded from the checklist.
  • Never give medications to your cat without first consulting your veterinarian.
  • Additionally, many commonly used human medications (such as paracetamol) are extremely toxic to cats.

How to Check a Cat for Fever

Infections are the most common cause of feline fevers, accounting for 95% of all cases (usually an abscess caused by a bite from another cat). Generally, body temperature returns to normal either on its own or with the use of drugs to treat the illness in most situations. There are rare situations in which fever persists despite basic testing and no evident reason of the elevated temperature can be identified – in these cases, the disease is referred to as ‘Fever of Unknown Origin,’ abbreviated FUO.

Depending on whether or not your cat’s temperature remains elevated after a few days of therapy, your veterinarian may decide to do additional tests to try to determine the source of the problem.

Some tests will need to be done a number of times in order to confirm or rule out a specific diagnosis.

It may, however, be possible to attempt drugs to lower the fever if certain conditions have been eliminated from the checklist after certain conditions have been excluded from the checklist.

Additionally, many commonly used human drugs (such as paracetamol) are extremely toxic to cats. Occasionally, in cats with unexplained fever, the fever may disappear without therapy, but it may reappear months or years later, again with no obvious explanation.

  1. 1 Keep an eye out for changes in conduct. It’s possible that your cat’s reclusiveness is a clue that he or she is unwell if your cat is ordinarily lively, energetic, and sociable. A hint that anything is wrong is if it starts hanging out beneath your bed, couch, table, or any other out-of-the-way, strange location. In spite of the fact that cats might be playful and curious on any given day, they are innately cautious creatures. Your cat will try to hide from you if he or she is sick, in order to lessen his or her susceptibility. 2 Take notice of how much your cat enjoys eating. If your cat is accustomed to eating at a given time of day or consumes a certain amount of food on a daily basis, it may change its feeding habits if it is ill or injured. Make frequent checks on your cat’s feeding bowl throughout the day to see whether it has consumed anything.
  • 1 Keep an eye out for any changes in your behaviors. It’s possible that your cat’s reclusiveness is a clue that he or she is unwell if your cat is usually lively, energetic, and sociable. A hint that anything is wrong is if it begins to hang out behind your bed, couch, table, or any other out-of-the-way location. In spite of the fact that they may be lively and interested on any given day, cats are innately cautious creatures. Your cat will try to hide from you if he or she is sick in order to lessen his or her susceptibility. 2 Consider your cat’s hunger when you are out and about. If your cat is accustomed to eating at a given time of day or consumes a set amount of food on a daily basis, it may change its feeding habits if it is unwell. Regularly check your cat’s food bowl to see whether it has eaten anything over the day.

3Be on the lookout for nausea or vomiting. The majority of feline illnesses, ranging from colds to more serious diseases or disorders, result in fevers, but they may also manifest themselves in other symptoms like as vomiting and diarrhea. Examine the area where your cat’s litter box is located. In rare circumstances, your cat may try to bury the object in question. If you have an outside cat, make an effort to keep up with it. Its resting regions should be checked for disturbed earth if it regularly buries its operations.

This is a difficult sign to recognize because cats are famously sluggish creatures to begin with.

If your cat generally follows you from room to room, but is satisfied to spend the whole day resting in a room far away from you, it may be suffering from sluggish behavior.

  1. Using an ear thermometer that is specifically developed for cats and dogs is a good start. These feature longer arms, which allow them to more easily reach into the pet’s ear canals. These thermometers are available for purchase at pet specialty stores as well as some veterinarian offices. In general, these thermometers are not as efficient as rectal thermometers in measuring body temperature. In the event that your cat is feisty, an ear thermometer may be preferable than a rectal thermometer
  2. 2Contain and restrain your cat. With their paws on a surface, they should be able to hold their body in place (try using the floor). Make sure you have a tight grip on its head with your arm. It’s important not to let your cat buck or jerk its head away from you when you’re checking its temperature. If you have the option, get a friend to assist you with this as well
  3. 3 Make a deep incision into the animal’s ear canal with the thermometer. In order to identify when the reading is complete, refer to the manufacturer’s instructions. The time it takes for an ear thermometer to detect a temperature is nearly the same as the time it takes for a rectal thermometer. Four minutes or so will be required. Remove the thermometer off the table and put it away. After using the thermometer, you should thoroughly clean it with soapy water or rubbing alcohol, just as you would with any other thermometer. After you’ve completed this task, store the thermometer in a safe location.
  1. 1 Prepare the thermometer in advance if you can. It’s important to thoroughly shake any mercury-containing thermometer you’re using. A digital thermometer can also be used, and it normally provides a more accurate reading more quickly. If possible, use a disposable sleeve along with a digital thermometer. Using petroleum jelly or another water-based lubricating jelly, lubricate the thermometer needle. KY Jelly or Vaseline are both effective. Your objective is to make this as stress-free as possible for the cat throughout this procedure. Using lubricant can assist reduce the likelihood of abrasion, tearing, and puncturing
  2. 3 Make sure the cat is in the proper position. Hold the cat under one arm, like a football, with its tail pointing in the direction of your body’s center of gravity. Make certain that its feet are resting on something substantial, such as a table. As a result, the risk of scratches will be reduced.
  • If at all feasible, enlist the assistance of a buddy to assist you in holding the cat. Some cats are wiggly and it may be tough to restrain them from moving about. Have your assistant arrange the cat in such a manner that you can easily put the thermometer into its rectum
  • You may also want to grip and hold onto your cat’s scruff to keep it from moving (extra skin on the back of its neck). Many cats identify this with their mother’s protection, which suggests that it may be soothing.

4 Insert the thermometer into the cat’s rectum with the tip facing up. Make sure to only insert the thermometer about 1 inch into the hole (2.54 cm). Do not go deeper than 2 inches into the ground. Make sure to hold the thermometer at a 90-degree angle so that it enters your cat’s rectum directly. No other angle should be used to enter since doing so will enhance the risk of experiencing pain and discomfort.

  • If you are uncomfortable taking your cat’s temperature, you should take it to the veterinarian.

Maintain the temperature reading for roughly 2 minutes with the thermometer in place. If you are using a mercury thermometer, it may take a bit longer to achieve an accurate temperature reading. You should keep your hand on a digital thermometer until the display shows that it has completed reading the temperature. The majority of digital thermometers will emit a beep when they are done.

  • Ensure that your cat is securely restrained throughout this operation. It may wiggle, scratch, or bite at your ankles. Make every effort to keep it motionless in order to avoid damage to both your cat and yourself.

6 Take a look at the outcome. A cat’s optimal temperature is 101.4 degrees Fahrenheit (38.55 degrees Celsius), although its temperature can fluctuate from 100 to 102.5 degrees Fahrenheit (39.17 degrees Celsius) and still be considered normal.

  • 6 Go through the outcome with your group. 7 A cat’s optimal body temperature is 101.4 degrees Fahrenheit (38.55 degrees Celsius), however his temperature can fluctuate from 100 to 102.5 degrees Fahrenheit (39.17 degrees Celsius) and still be deemed normal.

7Remove the thermometer from the cabinet. To clean and disinfect the thermometer, rinse it well with warm soapy water or rubbing alcohol. If you used a cover sheet to protect the thermometer, remove it and wash the thermometer according to the manufacturer’s instructions. Before storing anything, be certain that it has been fully cleaned.

  1. 1Take your cat to the veterinarian if his or her temperature is below 99 degrees Fahrenheit or above 102.5 degrees Fahrenheit. A fever in your cat is usually treatable by itself, but it is always a good idea to contact with your veterinarian if you are concerned. If your cat has been unwell for several days or you believe that he or she has a chronic ailment, it is even more critical that you take him or her to the veterinarian
  2. 2Explain your cat’s symptoms to the veterinarian. In addition to informing your veterinarian that your cat has a fever, be sure to inform your veterinarian of any other symptoms that your cat has displayed. This is critical information that your veterinarian can use to make a diagnosis
  3. However, it is not required. 3Follow your veterinarian’s directions to the letter. In certain cases, you may only need to provide your cat with water and comfort, depending on the veterinarian’s diagnosis. Depending on whether your veterinarian detects an illness or anything else, you may be required to provide medication.
