I always had both cats on Science Diet from advice of the vet then Simon went on the AD food from the vet's. It helped for awhile but he became sensitive to all food. He went from throwing up once in awhile to almost evryday.

I made sure both cats had tons of water at all times and both liked to drink it. I didn't want them to develop the kidney problems and I know they do if they do not have enough water in their food or otherwise.

My one cat lived a long time but he was always bothered by a sensitive stomach. It would be nice to know if any cat I get in the future is free of this problem.
