This is what I am beginning to believe. I have looked at several sources of information for this (some right here at Yahoo Answers) and it looks like dry food is essentially unhealthy for your cat. My cat is quite possibly diabetic, and it really looks like he should not have any dry food, and that includes the dry food made specifically for diabetic cats. Now, I have seen cats live a long time eating only dry food. But maybe they would have been even healthier and had greater longevity without it. What do you think?
