Why is my cat pulling out fur and losing hair on his groin area?

Hi - I have been worried about my cat for about a week now. We noticed that he was nibbling at his fur in his groin region, so we de-flead him, our other cat, and the house, but he still seems to be doing it. As you can see, the fur has become very thin in that area where he is pulling it out (in the photo, we have bathed it with some water and diluted hibiscrub). Do you know what this might be and how we can help him?

Thank you for contacting Petco Pet Education Center, formerly Petcoach with your question about Duncan. Poor boy, that's a lot of hair loss. He could have a flea allergy if he had fleas before, this could be due to mites, or it could be he's over-grooming from stress or illness. Without seeing him in person, I can't say for sure what is going on. I'd have him seen by a vet to have this diagnosed and treated. Best of luck.

A thinning hair coat on that particular spot in animals is often the result of a flea allergy. Fleas are very hard to find on cats as they often groom them before we see them. The hair loss is a result of the scratching and over grooming. Get a good flea medication such as advantage or bravecto. IF the hair continues to thin or he developed sores, then I would take him in
