Cats can't tell us when they aren't feeling well, so it's up to those who care for them to watch for signs of illness. A cat's fever can happen for a variety of reasons, including an infection, virus or parasites. Knowing the signs can help you get to the root of the problem and get your cat feeling better.
Instructions
Watch your cat for signs of illness. A cat with a fever will generally be more lethargic than normal and will not have a normal appetite. Knowing your cat's normal activity level and characteristics can help you determine if she is acting differently. Other signs of infection include shivering, rapid breathing and tenderness when touched.
Take your cat's temperature rectally with a lubricated digital thermometer. A normal cat's temperature is between 100.5 and 102.5 degrees. In hot weather, a stressed-out cat could have a 103 degree temperature. Anything above a normal temperature must be watched with caution.
Check your cat over for wounds or injuries. An infected wound can cause a fever. Likewise, if your cat has recently been spayed or neutered and is not returning to normal, the incision may be infected.
Know your cat's medical history. An FCoV test can tell you whether your cat carries feline infectious peritonitis, or FIP. Studies show that many cats carry this disease, and it can cause fevers in kittens, older cats or those with compromised immune systems.
Take your cat to the vet. The vet will diagnose whether your cat has a fever or not. If so, your vet can begin the appropriate treatment to help your cat and prevent dehydration.
