Hello. My hyperthyroid cat has been very itchy and my vet thinks it's a reaction from taking thyroid medicine so I was told to switch him slowly over to Hill's brand thyroid food as I wean him off of pills. Hill's seems to be the only company that makes thyroid food. I've heard Hill's brands are awful and to stay away from them. Does anyone know of another brand that makes thyroid control food? After doing a bit of research- some people on different websites say that Hill's thyroid food isn't completely balanced. Anyone treated their hyperthyroid cat with this food? What were the results? My cat is also at the very beginning stages of kidney disease.
