The study does seem to be very shallow as far as how they came up with their answers. It does warrant a much closer look, but I too would be interested in the cats preexisting conditions, what was in the food, what the quality of the food is, etc. Im trying to tell myself that a wet food diet is still better regardless of this concern, at least until the study is corroberated (sp?). If they come up with something conclusive, I will strongly think about switching away again. Being the study is 18 months old, I would hope that if it was a truly convincing study, we wouldve heard more about it, and they would be working on a different type of lacquer or dropping the pop top cans all together (at least the healthier companies).
Shengmei, dont feel bad about where you live and lack of large canned cat food. I live in a very busy area, and the pet store I was at the other day had very very few 13 oz cans. It is a bit frustrating.
