We have two brother tabby's, and they loved this dry food. Unfortunately 1 of them stopped going to the toilet which caused us concern. After a vets trip we were told our ginger tabby had developed crystals in the badder causing much pain. The vets told us that 'Go-cat' dry food is one of the worst for causing this. I don't wish to put this product down as my cats loved it, but this is a word of warning..... Make sure your cats drink a lot of water with this food. Our cats are now on special urinary tract food which cost circa 3 times the price of Go-cat, and they have to be on it for the rest of their lives...they are only 2.
