I feed my cats and dogs raw liver and kidney every week - liver once and kidney twice, mixed in with muscle meat. Cats are prone to kidney disease and dogs heart disease. I have noticed that when they are slightly off colour, the cats will eat the liver or kidney but leave the muscle meat. An aha moment from your info here. So I must bring in heart for the dogs, now. Thank you! Nature is so perfect. All we have to do is to bow before her wisdom and interpret it correctly.
