How Do You Diagnose a Medical Problem in Your Cat Based on the Symptoms?

Changes in a cat's behavior and habits may indicate signs of illness, according to Petfinder. Some of these warning signs include changes in interactions, activity and weight.

Although cats generally need less medical attention than dogs, cat owners should still regularly take their cats to the vet to check for any signs of illness. There are also certain behavioral and characteristic changes that cat owners should look for, says Petfinder. Sick cats may have dramatic changes in personality. For example, they might become clingy if they were previously more independent. A decrease in activity may also be a signal of cat illness.

Cat owners should pay attention to significant increases or decreases in their pets' food and water intake as well as chewing habits, as these can also be indicators that something is wrong, notes Petfinder. If a cat has bad breath, that can be a sign of several health problems including digestive issues or kidney disease. Changes in grooming and sleeping habits can also be signals of stress and illness. It is also important to watch for signs of mental illness in cats, such as anxiety. Anxious cats may show changes in behavior such as often missing the litter box.
