My Romeo had PU surgery last June after repeatedly getting crystals in his urine. The surgery seems to be successful but I'm having problems feeding him and my other 10 cats. My vet said that because he had crystals, he can never eat anything but prescription food again. I started using Hills to feed Romeo and the other cats but it's so expensive! I'm on a fixed income and money is pretty tight. I'm now trying feeding the other cats non-prescription food under my supervision and feeding Romeo separately. Unfortunately, Romeo realizes what is going on and is now refusing to eat his Hills and when he decides he doesn't want to eat, it's very difficult to change his mind. Does anyone else have a similar situation?
