The white tripe is useless. It has been sterilized. Green Tripe is only lightly washed so it still has some plant matter, digestive enzymes, and probiotics on it. You won’t find it in a grocery store. It’s too gross.
Heart is considered muscle, but it still has good things in it like taurine, that aren’t found much of anywhere else. Liver, kidney, spleen are the main organs. I buy whole carcass rabbit and quail grinds from Hare Today, because they have brain, eyes, pituitary, you know, ALL the organs, glands, everything. I feed whole carcass once a week. They even sell whole small animals, but all the squeamish people in my house would die if I fed that.
