If the animal’s body temperature hits 106 degrees Fahrenheit or above, it has a severe fever that requires emergency medical attention. Cats are at risk of brain and heart damage, as well as mortality, as a result of these higher temperatures.

A fever is commonly associated with an ailment, disease, or condition. Prepare to talk about your pet’s medical history as well as any symptoms you’ve noticed.

The veterinarian will perform a comprehensive medical examination and may obtain blood and urine samples for testing. To identify why the cat’s body temperature is raised, a comprehensive blood panel and tests for several viral or inflammatory illnesses may be required. X-rays or other diagnostic tools may be used by veterinarians to look for evidence of infections, injuries, or malignancies. If the reason for the fever cannot be discovered following thorough diagnostic efforts, the patient will be diagnosed with a fever of undetermined source.

Treatment of Fever in Cats

Fever in Cats – When treating a fever, the primary focus will be on maintaining hydration and lowering the temperature, with additional treatments varying depending on the underlying condition. It’ll be crucial to keep your cat hydrated as they fight the fever. Make sure your cat has fresh, clean water that is conveniently accessible from wherever they want to relax.

Antibiotics may be required if the source is a bacterial infection, for example. Intravenous or subcutaneous fluids are administered to treat moderate or severe dehydration. The following are some frequent treatments:

  • Antibiotics: Because infections are a prominent cause of fevers, antibiotics are commonly used to treat them.
  • Fever-Reducing Drugs: Some pain-relieving and anti-inflammatory medications, such as nonsteroidal anti-inflammatories (NSAIDs) that are safe for cats, are beneficial in reducing fevers, but seek medical counsel first.
  • Fluids, intravenous (IV), or subcutaneous (SQ): If the cat is dehydrated, fluid therapy is required.
  • Corticosteroids: These medications are used to combat inflammation, which is a common cause of fever.
  • Surgery: Surgery may be required to remove the source in situations of serious illness, tumors, or certain parasites.

While your pet has a fever, they will need to maintain an acceptable caloric intake, therefore some dietary adjustments, such as nutritious meals or possibly high-calorie beverages, may be required to aid in their recovery. Never administer medication to your cat without first consulting your veterinarian. Cats are poisonous to several fever treatments, such as acetaminophen.
