I have a cat who is about 15 years old. She is primarily an outside cat and has never really had any health problems. She is now starting to develop bald spots in her coat. They started out small on her stomach, but today I found a large one on her back. The skin where the hair is missing doesn't look irritated or abraided. Do yu have any ideas on what might be causing this?
No, I would need to examine your pet for a diagnosis. I recommend a vet visit. vetcare
