My 7 yr old long hair cat started to lick her hair off her stomach and legs a few months ago and now she is bald form the waist down. I tried , sprays, lotions, changed her food, water,cat valiun,, took her to the vet and $300 latter she still is licking. What the heck ?? I am now trying cramberry juice, and that is not working. Any one have a idea ??
