My cat is about 13 years old and for as long as i can remember, she's been grooming and tugging on her fur at the same time. The fur on her back is much shorter than the rest, from all the pulling! The vet originally said it was an allergic reaction to fleas...although she's an indoor cat. I've was using the flea drops once a month on the back of her neck and it seemed to let up a bit. Now just recently she's doing it again.... How can I tell (without spending big $$$) if it's a food allergy, fleas, or some sort of stress disorder?. I'm thinking stress related, 'cause we just moved a couple of months ago, and also got a new parakeet. But she was also doing this YEARS ago, for no apparent reason. She is all white, long hair, beautiful!, besides the reverse Mohawk on her back! :roll: She's my baby and I hate seeing her pulling her fur, especially if the food I'm giving her is causing it.
