I don't have a cat . . .

I have lost three cats to kidney/bladder problems over the last 26 years and have wondered if the food plays a roll in their problems. So actually, I am on a quest to find the best cat food I can. I was feeding a high protein food, but the local stores have quit carrying it. Off to do more research.

I'm not a cat person, but on a pet food forum I'm a member of, it's recommended that cats not be fed dry food for this reason. They should always be fed canned food. The reason seems to be that cats, by nature, don't drink enough water, and that they need the canned food to provide enough moisture in their diet to avoid kidney/bladder problems, crystals, etc.
