Dr. Pitcairn's New Complete Guide to Natural Health for Dogs and Cats

I, personally, wouldn't attempt a raw/home made diet without consulting (and monitoring) from a vet knowlegable in this regards. I know many who first transitioned their cats to a wet canned food diet and then to a raw/home made diet.

With all the recalls and poorly manufactured foods for cats many have turned to home made with great success. Good luck with your research!
