The raw materials these food manufacturers mix together to produce typical pet foods you find along the supermarket aisles come from highly questionable, and in some cases, unbelievable sources unfit for either person or beast. Compounding this situation is the fact that pet food labels give only vague ideas of a pet food's content. Lacks ingredients that should be part of our pet's daily food diet. Package labeling is a necessary obligation the food manufacturers are required to provide by law. These laws however, perpetuate a classification system that has little to do with nutritional value.
Manufacturers can and do use obscure and easily misunderstood terms.
The first and most important question to ask, for a better indication of the nutritional value of food we buy, is what percent of the food is digestible. A substance is a nutrient only when it is digestible, that is, absorbed and assimilated by an animal consuming the food product. Unassimilated food ingredients are at best, non-digestible roughage, and, at worst, deadly toxins or poisons. Nowhere on the pet food label does it state how much of the food can be digested. Pet and baby foods are unlike any other products sold in a supermarket.
