From what I have read the fat content should be no higher than 5% and the protein level should be no higher than 18%. Of course this info was obtained on the web so no idea as to its accuracy.
I know that Darwin's just created a RX raw food but you have to have a prescription to order it. Maybe you could show the info to your vet and see what they say about it. My vet is very against raw food period but Piper has done so well on it that I'm going to continue feeding raw but on a side note, she has never had any pancreas issues.
