I use the NuCat vitamins with my raw food diet I make for my cat. Thanks SCM for the NuCat link. I have been buying it from my vets office for about $10 to $15 more than what I can buy it for on this site (shipping and exchange included). I think their Prozyme is cheaper as well. I will have to double check. I use the Prozyme once in a while for my cat in his raw food. He has a sensitive stomach and it helps him digest his food easier
