My black & white cat, Pitzel, started to scratch alot and is getting bare patches. The vet thinks she has an allergy and gave me antihistamines for her. I don't think she is FLV positive. The point is, she won't let me give her pills. So I decided to buy a highly nutritious cat food- Nutro Max- and am giving it to her, thinking that maybe she is lacking some nutrient. I think it is helping somewhat. Am I doing the right thing? Any suggestions? She appears otherwise healthy and has a good energy level. RUTH
