So I have a cat over a year old and has some sort of food allergy. Our vet and I have been on this food trail for about 6 months. He takes hills Z/D wet and dry. He has been doing great on it. For the past month I felt bad for not being able to give him treats. So I decided to give him treats with just chicken ingredients and he has not had any reactions to it at all. (No scratching on ears or excessive licking) so now I’m thinking maybe I can change his food? With just chicken ingredients? I’m looking for alternative food for him. Because the hills zd is very expensive and sometimes it’s hard to find cause most places are sold out of it. Any help with suggestions will help greatly.
