The concept is simple: include the fresh, whole foods that nature evolved dogs and cats to eat (in correct ratio and quantity), and exclude ingredients like cereal grains that are not part of the natural diet. 

High-protein, low-carbohydrate and grain-free, ORIJEN features fresh regional ingredients in a Biologically Appropriate ratio of 70 percent meat, 30 percent fruit and vegetables and zero grain (70/30/0).

The metabolism of cats and dogs is naturally evolved to operate on a largely carnivorous diet, and by better matching the natural diet, ORIJEN promotes peak health in cats and dogs of all breeds and life stages, nourishing them as Nature originally intended.  ORIJEN is a new direction in pet nutrition: BIOLOGICALLY APPROPRIATE.
