Understanding Fever in Cats
To effectively address the issue of high temperature in cats, it’s important to have a clear understanding of what constitutes a fever and the normal body temperature range for cats.
Normal Cat Body Temperature
The normal body temperature range for cats typically falls between 100.4º to 102.5º Fahrenheit (WebMD). The range can vary slightly, with different sources citing temperatures in the range of 100.5º to 102.5º Fahrenheit (VCA Canada) and 99.5º to 102.5º Fahrenheit (Paoli Vetcare). It’s important to note that individual cats may have slightly different baseline temperatures, so it’s essential to be familiar with your cat’s normal temperature.
Definition of Fever
A fever in cats occurs when their body temperature rises above the normal range. While a mild fever may be the body’s natural response to fight off infections, it’s important to monitor and address high temperatures to prevent potential organ damage. A fever is generally considered significant in cats when the temperature exceeds 103.5º Fahrenheit for an extended period. In extreme cases, a fever higher than 106º Fahrenheit can be dangerous and requires immediate veterinary attention.
Understanding the normal body temperature range for cats and the definition of a fever provides a foundation for identifying and addressing high temperature in felines. In the following sections, we will explore the causes, symptoms, diagnosis, and treatment of fever in cats.

Causes of Fever in Cats
When cats run a high temperature, it is indicative of a fever. There are various factors that can cause fever in cats, including infectious diseases and inflammatory conditions.
Infectious Diseases
Infectious diseases can be a significant cause of fever in cats. Exposure to highly contagious diseases such as Haemobartonellosis, ehrlichiosis, bartonellosis, and toxoplasmosis can trigger a fever in cats, especially in outdoor cats that frequently come into contact with other animals (Carolina Veterinary Specialists). These diseases are often transmitted through close contact with infected animals or exposure to contaminated environments.
Fever can also be associated with other infectious conditions such as pneumonia, feline immunodeficiency virus (FIV) infection, upper respiratory tract infection, bite wounds, peritonitis, pleural effusion, panleukopenia, and sepsis (Today’s Veterinary Practice). These diseases may cause an inflammatory response in the body, leading to an elevated body temperature in cats.
Inflammatory Conditions
Inflammatory conditions can contribute to the development of fever in cats. These conditions can include various underlying factors, such as infections, injuries, or immune-mediated diseases. When the body detects an injury or infection, it responds by initiating an inflammatory process, which can manifest as fever.
For instance, cats with histoplasmosis, a fungal infection, may present with relatively vague clinical signs, including fever. In a study, approximately 34% of cats with histoplasmosis were reported to have a fever. Diagnosis of such conditions may require additional tests such as liver, bone marrow, or splenic aspirates to confirm the underlying cause when typical symptoms like pulmonary involvement and lymphadenomegaly are not apparent.
Toxoplasmosis, another inflammatory condition, can also result in fever in cats. A retrospective study found that fever was identified in 73% of cats with confirmed toxoplasmosis (Today’s Veterinary Practice). This parasitic infection can cause acute or chronic disease, and fever is a common symptom in both presentations.
Identifying the underlying cause of fever in cats requires veterinary expertise. A thorough examination and diagnostic tests are necessary to determine the specific infectious or inflammatory condition causing the fever.
Understanding the causes of fever in cats is essential for prompt diagnosis and appropriate treatment. If you notice signs of fever in your cat, such as an elevated body temperature along with other symptoms like lethargy, loss of appetite, or behavioral changes, it is crucial to consult a veterinarian for a comprehensive evaluation and appropriate management.
Symptoms of Fever in Cats
When a cat runs a high temperature, it’s important to recognize the symptoms of fever in order to provide appropriate care and seek veterinary attention if necessary. Fever in cats can manifest through both behavioral and physical signs.
Behavioral Signs
Cats with a fever may exhibit changes in their behavior. These behavioral signs can include:
- Lethargy: Cats may become unusually tired and lack energy.
- Reduced appetite: A fever can lead to a decreased desire to eat or drink.
- Increased sleep: Cats may spend more time sleeping or appear less active.
- Hiding: Cats may seek out secluded areas or hide more frequently.
- Avoiding activities: Cats may show a reluctance to engage in activities they normally enjoy.
It’s important to note that these behavioral signs can vary depending on the individual cat and the underlying cause of the fever. Other symptoms, such as vomiting or diarrhea, may also be present depending on the cause of the fever. For more details on the symptoms of fever in cats, refer to our article on cat fever symptoms.
Physical Signs
In addition to behavioral changes, there are physical signs that may indicate a fever in cats. These physical signs can include:
- Increased heart and breathing rates: Cats with a fever may exhibit an elevated heart rate and rapid breathing.
- Dehydration: Fever can lead to dehydration, which can be observed through dry gums and skin tenting (when the skin does not spring back when gently pulled).
- Warm face or ears: Cats with a fever may have warm areas on their face or ears.
It’s important to monitor your cat’s temperature regularly to confirm the presence of a fever. If your cat exhibits any of these physical signs, it’s essential to consult with a veterinarian for a proper diagnosis and treatment plan. For more information on diagnosing and treating fever in cats, refer to our article on how to treat fever in cats.
Remember, persistent or recurring fevers should always be evaluated by a veterinarian to identify and address any underlying medical conditions before they worsen. Early diagnosis and appropriate treatment can help ensure a speedy recovery for your feline companion.
Diagnosing Fever in Cats
When it comes to diagnosing fever in cats, there are two main methods that veterinarians use: temperature measurement and veterinary examination.
Temperature Measurement
The most accurate way to determine if a cat has a fever is by taking their temperature. A pediatric rectal thermometer is the most commonly used tool for this purpose. It is important to use a digital thermometer, as it is safer than a glass thermometer and provides a signal when it’s time to check the reading. It won’t shatter if accidentally dropped, ensuring the safety of both the cat and the person handling the thermometer.
To measure a cat’s temperature at home, you can use a digital thermometer in the ear or rectum. Ear thermometers designed specifically for cats are a less invasive option, while rectal thermometers provide the most accurate readings. It’s important to follow the manufacturer’s instructions carefully to ensure accurate temperature measurement.
The normal body temperature range for cats is between 100.5°F and 102.5°F (38.1°C and 39.2°C). A fever in cats is classified as a body temperature above 103.5°F (39.7°C) that persists for more than a few days without an obvious underlying cause. This is known as a fever of unknown origin (FUO) (VCA Canada). For a more comprehensive diagnosis, it is recommended to consult a veterinarian.
Veterinary Examination
In addition to temperature measurement, a thorough veterinary examination is essential for diagnosing fever in cats. During the examination, the veterinarian will assess the cat’s overall health, look for any physical signs of illness, and inquire about any behavioral changes or other symptoms observed by the cat owner.
The veterinarian may perform additional tests, such as blood work or imaging studies, to identify the underlying cause of the fever. These diagnostic tests help rule out infectious diseases and inflammatory conditions (WebMD). It’s important to keep in mind that fever is a symptom rather than a specific disease, so identifying the underlying cause is crucial for appropriate treatment.
If you suspect that your cat has a fever, it is recommended to consult a veterinarian for an accurate diagnosis. They will be able to perform the necessary examinations and tests to determine the cause of the fever and provide the appropriate treatment.

Treatment for Fever in Cats
When it comes to treating fever in cats, the approach may vary depending on the underlying cause and severity of the fever. In most cases, treatment for fever in cats involves a combination of antibiotics and supportive care.
Antibiotics
Antibiotics are often prescribed to treat any underlying bacterial infection or to prevent bacterial infections from occurring as a secondary problem in cats with fever of unknown origin (FUO). These medications target bacteria and help eliminate the infection, which can contribute to the fever. It is essential to follow the veterinarian’s instructions regarding the dosage and duration of antibiotic treatment.
Supportive Care
Supportive care plays a crucial role in the treatment of fever in cats. This may include various measures to provide comfort and aid in the recovery process. Some aspects of supportive care may include:
-
Fluids: Dehydration is a common concern in febrile cats. Administering fluids is important to maintain hydration and restore electrolyte balance. Depending on the severity of dehydration, fluids may be administered subcutaneously or intravenously.
-
Temperature regulation: Cats with a high fever may benefit from efforts to cool them down. Applying cool towels or using fans can help dissipate excess heat. However, it is crucial to ensure that the cat does not become too cold, as extreme temperature fluctuations can be detrimental.
-
Comfort and rest: Providing a comfortable and stress-free environment is essential for cats with fever. Ensure they have a cozy and quiet space to rest, away from excessive noise or activity.
-
Monitoring: Regularly monitoring the cat’s temperature is important to track the progress of treatment. This can be done at home using a rectal thermometer, following proper guidelines to ensure safety and accuracy. If the fever persists or worsens, it is important to consult with a veterinarian for further evaluation and guidance.
It is important to note that fever in cats can be a symptom of an underlying condition. Therefore, seeking veterinary care is crucial for a thorough examination and diagnosis (Preventive Vet). A veterinarian can determine the appropriate treatment plan based on the specific needs of the cat, address any underlying issues, and provide guidance on managing the fever and promoting overall well-being.
Prevention of Heat Stroke in Cats
Preventing heat stroke in cats is crucial to ensure their well-being, especially during hot weather. By understanding the risk factors and implementing preventive measures, you can help keep your feline companion safe and comfortable.
Risk Factors
Certain cats are more susceptible to heat stroke than others. The following are some common risk factors to be aware of:
- Outdoor cats on very hot or humid days: Cats who spend time outdoors, particularly in extreme heat or high humidity, are at a higher risk of developing heat stroke.
- Indoor cats without power or air conditioning: Cats kept indoors without access to air conditioning or proper ventilation may be more prone to heat stroke during heatwaves.
- Flat-faced (brachycephalic) cats on warm days: Breeds with flat faces, such as Persians or Himalayans, are more susceptible to heat stroke due to their compromised ability to cool themselves.
- Obese cats: Overweight or obese cats have a harder time regulating their body temperature, making them more vulnerable to heat stroke.
- Senior cats: Older cats may have diminished heat regulation mechanisms, making them more susceptible to heat stroke.
- Kittens 4 months old or younger: Young kittens have underdeveloped thermoregulatory systems, making them more prone to heat stroke.
- Cats with underlying health conditions: Cats with pre-existing heart, respiratory, or neurological issues may have reduced heat tolerance and are at a higher risk of heat stroke.
Preventive Measures
To prevent heat stroke in cats, it’s essential to take proactive measures to keep them cool and comfortable. Here are some preventive measures you can implement:
- Provide access to cool, shaded areas: Ensure your cat has access to cool and shaded areas both inside and outside your home. This can include providing a well-ventilated room or a shaded outdoor space where they can find relief from the heat.
- Fresh water availability: Always provide fresh, cool water for your cat to drink. Consider placing multiple water bowls throughout your home, especially in areas where your cat spends the most time.
