Answer:
Wysong foods are holistically designed and emphasize meats, organs and nutraceuticals. This, as in the wild diet, presents a broad spectrum of nutrients for carnivorous metabolism to select from.

In contrast, commercial foods that are reductionistically designed using food fractions, may indeed need different nutrient profiles for canines and felines.

To make this more clear, a food that is created using food fractions and synthetics will need a different menu of amino acids for cats than for dogs. However, a food composed of natural prey meats and organs needs no such precision since the body of either the cat or the dog will select what it needs.

Proof that cats and dogs thrive on the same food can be found throughout nature, and in the hundreds of thousands of cats and dogs fed the same Wysong diets through multiple generations for the past 35 years.

Wysong healthy pet food diets are designed to mimic the animal's natural feeding patterns - what they are genetically adapted to. In the wild, cats and dogs fundamentally have a similar carnivorous (meat-based) diet.

Labeling cat and dog foods differently is largely a marketing strategy. However, this labeling tactic leads consumers to presume that there are fundamental and meaningful differences between dog and cat diets requiring the special skills of nutritionists and food processors. But this is not the case. If pet foods are designed properly--holistically-- they are appropriate for any carnivore. Particularly is this so if foods are rotated and varied as in nature and as described in the Optimal Health Program™.

The same rationale can be applied to our cat and dog supplements, most of which are cross-species (equally suitable for cats and dogs).
