Why does my cat have a fever? - briefly
A cat's body temperature typically ranges between 100.5°F and 102.5°F (38°C and 39.2°C). If your cat has a fever, it could indicate an infection or inflammation, which may be caused by viral, bacterial, or fungal infections, or even certain diseases like hyperthyroidism.
Why does my cat have a fever? - in detail
Cats, like humans, can develop fevers in response to various underlying conditions. A fever in cats is typically defined as a body temperature above 102.5°F (39.2°C) and can be indicative of an infection or illness. Understanding why your cat has a fever requires considering several potential causes and their associated symptoms.
One of the most common reasons for a cat to have a fever is a bacterial or viral infection. Respiratory infections, such as those caused by feline herpesvirus or calicivirus, can lead to elevated body temperature. Similarly, urinary tract infections (UTIs) and dental issues can also cause fevers. Infectious diseases like feline immunodeficiency virus (FIV) and feline leukemia virus (FeLV) are other possible causes of fever in cats.
Inflammatory conditions, such as inflammatory bowel disease or pancreatitis, can also result in a cat having a fever. These conditions often cause gastrointestinal upset, including vomiting and diarrhea, which may accompany the fever. Additionally, autoimmune disorders, where the body's immune system attacks its own tissues, can lead to fever as part of the inflammatory response.
Certain types of cancer in cats can cause fevers, although this is less common than infectious or inflammatory causes. Tumors and associated conditions can trigger an immune response that results in a fever.
In some cases, a cat's fever may be due to a reaction to medications or vaccines. While rare, adverse reactions to these substances can cause a temporary rise in body temperature.
It is essential to note that fevers in cats should not be ignored, as they can indicate a serious underlying condition. If your cat has a fever accompanied by other symptoms such as lethargy, loss of appetite, or difficulty breathing, prompt veterinary attention is crucial. Your veterinarian will perform a thorough examination and may recommend diagnostic tests like blood work, urinalysis, or imaging studies to determine the cause of the fever.
In summary, fevers in cats can be caused by a range of conditions, including infections, inflammatory disorders, cancer, and adverse reactions to medications. Prompt identification and treatment of the underlying cause are vital for your cat's health and well-being.
