The stomachs of ruminant cattle supply partially digested vegetable matter to the carnivore diet. Wolves do not eat the stomach contents of prey, but they eat the internal organs with smatterings of vegetable matter adhering to them. Green tripe is an unwashed cow stomach. It's not the most appealing meat but very good for your pets. Sliced tripe comes in bags of about 5 pounds. You will be charged for only the weight received.
