So, our cat in the past was given a urinary tract food by the vet in the past, and the expectation was for him to stay on it. However the problem we dealt with is that he seems to have skin issues related to chicken(we think), and almost every food for urinary tract issues has chicken somewhere in the ingredients. We found one that did not, but honestly he hasn't done well on that food. When we had a vet visit recently, they had no suggestions on chicken free food for it, but insisted we remain on a urinary tract based food. Any thoughts here?
