A thorough physical examination is an important part of routine wellness care for all cats. Cats are very good at hiding their illnesses, so a physical examination may be the only way to determine if your cat is as healthy as he or she seems to be. Even if your cat seems fine and has no evidence of problems, routine physical examinations are important for establishing “normal” values for you cat. For example, subtle changes in weight may only be noticed by comparing your cat’s current weight with readings recorded during previous examinations.
