Firstly I must say that I'm not a animal nutritionist. When it comes to feeding my two cats, Joe & Typha, I try to think about their natural eating habits. Felines are predators and as such gain the required vits/mins from their prey which they eat whole. I guess this way they are assured of getting a broad spectrum of nutrition. Raw meat alone will not replace a cats natural diet. If you were to feed your cat whole birds, fish, and mice then you might be close. I tend to feed my cats fresh raw meat at night including fish (sometimes pan fried fish when I'm feeling pathetic), lamb, beef, chicken and pork and a canned/tinned food in the morning. As with us I think variety is very important, I don't think any one food diet is good for a cat.
