Does Felix have a history of urinary crystals? If so, I would be very careful about making a homemade diet....in regards to magnesium content, resulting urine pH, etc. If your cat has any special dietary needs, I would consult a veterinarian for homemade recipes or a food therapy protocol. I work for a veterinarian trained in Traditional Chinese Veterinary Medicine and she does one-hour appointments to discuss food therapy and herbs for individual pets.

I don't have experience with raw, only homecooked. Two books with homecooked recipes for cats that I would recommend are:
Home-Prepared Dog & Cat Diets: the Healthful Alternative by Donald R. Strombeck
&
Dr. Pitcairn's Complete Guide to Natural Health for Dogs & Cats by Richard H. Pitcairn

Also switching a cat from addictive "crunchies" to foods with an entirely different texture can be very difficult. Be sure your cat never goes for more than 24 hours without food!
