We learned this lesson, too... I always thought that buying the more premium canned food meant better nutrition but it's just not like that. When a health issue came up and the vet suggested buying grain-free cat food (both wet and dry) was when I started realizing what was actually in (or NOT in) the stuff we'd been feeding her. And then I felt guilty for not having known before. I still check the ingredient list even on the grain-free foods, but it's never as shocking as some of the other "regular" cat food lists are. It also makes me wonder how some of those companies can even get away with the junk they're getting away with putting in our pet foods. :-(
