If my IBD cat is on a duck only diet but I feed her a canned food that has chicken fat in it, is it okay? Duck is the first and only meat listed. I am asking because she hates pâté foods, and that is what all of the LID canned duck foods seem to be. I was excited to find on chewy.com that Canidae Pure actually has a SLICED grain-free duck food, but it does have the chicken fat. Is chicken fat actually considered "meat"? I do not know if chicken is actually an issue for her or not. The vet said to keep her on the dry LID duck diet, which has been working until recently, but she is back to vomiting a few times a week. I think that the dry food may be too harsh on her stomach, but the vet will probably not agree with me. She thinks that the dry is better.
