here are a couple of great sites about switching over onto raw for cats...we have been on raw for just over a week with my two and they are LOVING it...although slightly fussy
What I have been most impressed about it that in just over a week, their back teeth which were all yellow have started to clean off already! I am very impressed...oh and they poop less and it is less smelly
Raw Fed Cats (the 'Practical Guide' page is really useful)
Raw Feeding Felines - Home Page (story of how someone on my raw feeding yahoo list transferred her cats over onto raw)
This is also very interesting for cats or dogs regarding some of the myths around raw feeding!
