I am very concerned about my cat's low weight and muscle wasting. He has had soft stools since the end of 2015. My vet told me to put myTimothy on Royal Canin Gastro food, which is mainly grains and is a high fibre diet to firm up his stools. It turned out my cat was hyperthyroid and that probably gave him soft stools. My vet had said my cat probably has a hard time digesting protein. I can't believe that I believed that nonesense! It took my vet 1.5 years or 5-6 different vet visits and many series of tests to figure out that he was hyperthyroid ! So in the mean time Timone had alot of muscle wasting from being on a mostly grain diet and being hyperthyroid. Because my vet couldn't figure out what was wrong and treat the underlying cause of his soft stools she decided to put him on a diet that is better suited for a cow than a cat. When I had resisted her advice early on and slowly overtime gave him a protein diet he got diariah and this makes sense since high fibre was keeping his stools firm. My cat is now on Hill's yd wet and dry, another low protein too many grains diet to control his hyperthyroid. He was allergic to thyroid pills and the only other option I seem to have is this awful food which is making his long term muscle wasting of close to two years now so much worse. I am frustrated that some vets don't seem to realize that a cat is a carnivore and not a herbivor and I wish they would stop pushing these awful foods onto vulnerable pet parents who are told that this is what their cat needs to get better. These vet brand food companies like Hill's and Royal Canin need to be held accountable for the times that they make pets sicker. I feel I can't depend on vets anymore to help improve my cat's health.
