I have the sweetest calico who is excessively grooming herself. It began last November, but didn't become a real problem until around February. I was gone from January through March. My daughter, who my 2 cats love, took care of them while living at my house. I thought if it was stress related that when I returned home and I showered her with attention she would stop. Although I gave her loads of attention she continued licking, so in June I took her to the vets. He didn't find any evidence of mites, fleas, fungus, etc. and thought it was allergy related. She received a strong dose of Depo-medrol which made her lethargic for 3 weeks, during which there was no excessive licking. But then it began again. Since then she has had 2 more injections of Depo-medrol and put on a diet of goose and potatoes for 8 weeks now. Her licking and nibbling has gotten worse. Her belly and thighs are bald and her one side is getting there. She is now working on her back. Has anyone's cat experienced this kind of behavior and might it continue until she has no fur at all? I can hardly stand to see her do this. Maybe I should try another vet? Could it be psychological?
