Why is my kitty losing weight?

My kitty is losing weight. His behavior is
completely normal and his appetite is still good.
Do I need to be worried?

Most pets experience fluctuations in weight during their lives. Healthy cats often lose or gain five or ten percent of their body weight during the course of a year. As long as no steady trend upwards or downwards occurs, minor weight fluctuations are no cause for concern.

However, if your cat is losing weight continuously, he could have a medical problem. Thyroid disease and diabetes frequently cause cats to lose weight despite a robust appetite. A number of other conditions also can lead to the scenario you describe.

I recommend a vet checkup for your cat. Your vet can confirm that he’s losing weight, and then, if necessary, run tests to ensure no medical problem exists.
