What can I do to help my cat quit pulling her hair out? Right now if we see her chewing on her hair we yell and make her stop, but her once thick, pretty coat is so thin it makes me want to cry. It started with fleas. Bro insisted his dog come in and dog brought fleas because bro has decided that flea medications are just poison designed to make your animal die so you buy more animals. Not kidding. The fleas are gone and she is being treated with frontline plus, which works well for her. The chewing did not stop. Are there things I can add to her diet? She eats mostly Taste Of The Wild dry food with greenies for treats. The food is well rated on the analysis sites. Once in a while she gets half a benadryl (up to 4 times a day per vet) but it doesn't seem to help the chewing. She seems to be chewing more out of anxiety than out of itching. Any help is appreciated!
