"I nearly Lost Tux with Stone blockage, and Vet told me in order to help these stones from forming again, I needed to change the diet. If I am going to have to for 1, the other Cat is going to have to follow, as I don't want it happening to him either...SO, I found something good for them, helping with their Urinary tract, that they will EAT!!! My 2 cats are picky!!! I was afraid this new diet they would hate, since it was a special diet food, but they sure fooled me! They eat it with no problems and they seem to like the chicken flavor. Cost was reasonable also. I would recommend. "
