But but but grain free kibble usually uses potato as their carbohydrate and really, is a potato chip more healthy than a corn chip? Besides, those upscale pet food companies who tout how they use actual *meat* in their foods? It's just BONES. You're buying nothing more than a bag of potato and BONES. Why yes, I did have the honor of sitting through a Hill's Pet Nutrition Lunch and Learn. Why do you ask? They're really big on "ingredients don't matter, nutrients do". I think that's a load of baloney, myself. I really need to get that In Defense of Food book. Sounds excellent.
