A raw diet—meats and greens that are fresh, uncooked and wild—is the diet that dogs and cats evolved to eat. Raw food is the nutrition nature intended for dogs and cats. It is more easily absorbed and contains vital naturally occurring enzymes and vitamins that cooking destroys.
In fact, until 50 or so years ago, our domestic pets ate what we did, usually in the form of leftovers and table scraps. Dry, pelletized pet foods—kibble—was unknown until the mid 20th century.
Convenience and marketing, rather than animal health, drove the growth of the pet food industry as we know it. Now, many vets are making the connection between pet disease and diet, just as healthcare professionals have shown us how our own dietary choices affect our health, and our companion animals suffer with cancer, arthritis, diabetes and many other human diseases.
