What could be the cause of a scab like rash all over a cat?
We got this kitty as a stray. she's the sweetest little kitty. we've only had her since December but she's been to the vet 4 or 5 times already. she's FIV positive, so we know her immune system isn't great. when we got her, she had this itchy bumpy rash on her head and neck. the vet told us it could be her food, so we switched it twice. now she eats iams canned food and the rash continues to get worse and worse- it's all over her body now and feels like a scab. still very itchy. they can't do steroids because of the FIV. the vet ran a billion tests and all were negative- no fleas, no parasites. her hair is fine, soft and full. but if you run your hand along her, you feel tons of scabs on her skin. the vet told us to try an allergy formula food (2.25 a can!!) and to give her antihistamines to make her more comfortable. she's also had diarrhea off and on, not sure if that's related or not. she was treated for roundworm when we got her, later stool samples were clean. the vet said that could be the food also. I just want to take care of my poor kitty cat- I don't know what to do!
