Q. My cat has fever of 104, decreased appetite and energy. No vomiting has occurred. What could be wrong with him?
DR. CHRISTIE LONG, D.V.M., C.V.A.
A. An elevated temperature can mean a number of things in a cat. I would worry about a contagious disease, but he could also have an abscess, especially if he's allowed to roam outside. Sometimes cats get into fights and the wounds caused by their claws or teeth can become very seriously infected and fester for a few days while the cat starts to feel worse and worse. Sometimes it's difficult to see the abscess, depending on location on the body.
A vet can do an exam and rule out an abscess, and then can recommend other testing to look for other diseases if there's no abscess.
