I've converted my cats to a raw diet over the last several months. I'm fortunate that here in the Twin Cities we have a local raw pet food store
(WFS) which supplies all kinds of different meats. I rotate the meats between chicken, duck, pheasant, turkey, etc. My one cat who is 16 years old with arthritis and kidney disease likes it just fine. The other is a bit more finicky so I mix with a more traditional canned cat food, grain free.
