My cat keeps biting his belly. Why is he losing fur and what can I do?

Updated on September 23rd, 2025

Pet's info: Cat | Mixed Breed | Male | neutered | 7 years and 11 months old

My cat sometimes has fleas and because of that he started biting his belly, that plus the fact that when he washes himself he also bites it, he now has no fur on that place. We've tried putting a collar on his head so that he couldn't reach his belly, but every time we take ir for him to clean himself, he goes back to his belly. I've no idea how to let the fur grow and if he has something else going on there, or if he's just stubborn. If there's anything I'm doing wrong, I'd like to know. Thanks

Such overgrooming in cats can be related to allergies or anxiety - feeding a calming food such as royal canin calm or adding a claming supplement containing b vitamins, tryptophan and casein can also help. Occasionally antiinflammatory medications may need to be prescribed by your vet in order to break the recurrent itch-scratch/groom cycle and allow the skin to heal

    Even if you don't see fleas, I would still recommend using a monthly flea preventative. Some cats can have an allergy to fleas, and all it takes is one flea bite to make them itchy all over. There are several other possible causes for his itching and pulling out his hair, including mites, allergies (fleas, food, environmental), ringworm, behavioral, among a few others. I would recommend that Kitty get checked out by a vet to see what could be the cause so that he can get the appropriate treatment.

    Here is a good article on overgrooming in cats and their possible causes:
