If you’re going to cook bone, just use bone meal. But none of the meat needs to be cooked at all. Would love to discuss enhancing his appetite. I also had my study, knowledge, and experience verified by a holistic pet food store which actually used the same book I did to learn about natural pet diets. Liver note: Liver should only be 5% of the total weight per feeding. Don’t overdose it, same as with humans.
