This would be interesting if there were links to studies done by experts in the area of animal nutrition. My veterinarian has told me she's in favor of NOT feeding cats or dogs kibble, and when I asked her opinion on the raw I feed my dog, she approved of it. It's hard to imagine dried kibble bits doing anything positive for the health of an animal over anything else (whether wet or raw or part raw or whatever). Raw and wet are more expensive, and not everyone can buy it, but they're definitely better than kibble. (I have a similar experience to the other commenter's, cats who ended up needing fewer vet visits, vomiting hardly ever as compared to pretty regularly, and no longer having crystals in a kidney after switching from kibble to wet - not even raw.)
