Our canned Bison Feast pet food is a convenient way to feed at home or on the go. Bison Feast is pressure cooked at very low pressure and low heat (just enough to stabilize the canning process). Ingredients include our 100% Grass Fed and Finished Bison muscle meat, a mix of our bison organs such as heart, tongue, spleen pancreas, and liver, crushed bones, our green bison tripe and some fortified vitamins. One said recently, "That's the cleanest, purest canned pet food I've ever seen." Great! But that's simply how nature was designed to be.
