Cats and dogs have different nutritional requirements based on their origins.
Dogs are facultive carnivores and descended from wolves, which form packs that thrive on large prey. Red meat from large ungulates such as cattle, sheep, deer and kangaroo are the most species-appropriate for dogs. The general guideline used by raw dog feeders is 80/10/5/5 – that is 80% meat, fat and skin, 10% bone, 5% liver and 5% other secreting organ – based on the rough average of the canine prey diet percentages.
Cats are obligate carnivores and descended from the African wildcats, which are small solitary hunters of smaller prey. However, as small domestically raised meat animals can be deficient in taurine today due to lack of exercise, we recommend feeding red meat from larger animals as well to provide cats with a rich source of taurine. The general guideline used by raw cat feeders, modified from the original canine guideline, is 83/7/5/5 – that is 83% meat, fat and skin, 7% bone, 5% liver and 5% other secreting organ – to account for the lighter-boned small prey.
