Just as we humans were not made to run on soda and junk food, our pets were not made to run on kibble. In this country the incidence of cancers and auto-immune disease in domestic animals has reached epic proportions. Only a few decades ago, these conditions were unheard of in animals. I am sure that nutrition plays an important role.
I firmly believe in a species-appropriate diet, both for our pets and for our livestock. The pet food industry would have us believe that their products provide perfect nutrition for every single pet, regardless of the needs of an individual animal. Yet again we are talking about highly processed “pseudo-food” stripped of all the nutrients, enzymes and vital energy that nature provided, and enriched with a handful of synthetic vitamins and minerals. That iss why I feed my dogs and my cat an organic raw meat diet.
