My oldest cat (about 6 years old) scratches herself so bad that she bleeds. It's only been happening for about a year, but has progressed over the last few months from just her neck to her entire body. She doesn't have fleas (we've done the baths and collars). I've taken to putting shirts/scarves on her to cover her body, but she's learning how to take them off. I came home from work today and her shirt was off and she'd scratched the left side of her body raw. She isn't bleeding, but her skin is pink and inflamed and her fur is sparse in those areas (from being ripped out). Could it be allergies? We've switched to grain free food (Blue Buffalo, mainly), give them filtered water and don't give them treats (they aren't interested). The other 2 cats haven't done anything like this. What should I try? We clip her nails as often as possible and tried the caps, but she chews them off within a day or so. I just want her to stop scratching and causing herself pain.
