the problem with the Pitcain's book is that this material is 25 years old -- badly out of date --

It has now been shown that cats should NOT be eating grains -- rice, soy, corn -- No!

They are STRICT obligate carnivores...they are not  small dogs....they need MEAT ONLY not cereal.

I know Pitcairn was considered good when it came out, but this is badly outdated information.

See Anne's recipe at www.catnutrition.org -- she is a nutritionist and did a lot of research to come up with that formulation so we can all be feeding our kitties correctly...
