Both species are equally popular as pets but each have diverse nutritional needs. Dogs can function more as omnivores than cats. Cats have remained as carnivores thought out their evolution. Cats cannot obtain their nutrients from plants and plant products and must consume some animal tissues in order to meet their needs for higher protein levels, taurine, arachidonic acid, and preformed vitamin A. Man has enhanced the ability for dogs to assimilate plant based foods because of the evolution of the kibble/grain based diets. I feel that the proper fuel for a dog however, is an animal based nutrient and one that has not been heat processed. Thus, the popularity of the BARF DIET (BIOLOGICALLY APROPRIATE RAW FOOD) has become an appropriate feeding choice for people that are more concerned than ever to feed their precious animals properly. The key and secret to this way of feeding is because of the presence of the exogenous (contained in the food) enzymes in the raw food. Learn the secret to longevity and good health for humans as well as dogs and cats. Read my book- “Living Enzymes- the world’s best kept pet food secret” (send me a comment and I’ll give you the ebook free).
