So a few months ago in the fall our cat very suddenly had these itchy spots all over his body and was chewing himself raw in places. We took him to the vet and she said allergies of some kind, most likely environmental seasonal allergies since it was fall and we live in the midwest. She gave him a steroid shot, which cleared the itching and spots up almost immediately and told us if it happens again, it is probably his food and not seasonal.
So here we are again with the itching and raw red spots. So I guess I’ll go out today and buy a different kind of food. But I have no idea where to start. Any advice on what to look for or possible ingredient culprits? Side note, I would prefer to not break the bank on cat food. He is currently eating Purina One Indoor formula. Possible culprits from looking at the ingredients could be turkey, corn meal, or soy. I’ve never had an animal with allergies so I don’t know where to start. He is the least picky cat in the world and will eat anything, so that’s not an issue. Thanks!
