I would highly recommend you find a holistic vet in your area. They will have the most experience and can monitor your cats progress and answer any questions you may have regarding raw feeding. You can do a search for one here at this site:Holistic Vet Search

There are also Yahoo message groups dedicated to people you feed raw diets to their pets. You can pick from this list: Yahoo Raw Groups
