4D meat means diseased, dying, decayed, and dead animals. Meat quality is very important because raw meat provides live enzymes needed for digestion and assimilation of nutrients. Raw, good quality meat also provides essential amino acids necessary to provide building blocks within the pet's body. Cat's can live solely on a meat diet because they are true carnivores. Therefore we must ensure that they are receiving wholesome, pure quality meat.
Dogs are more of a secondary-carnivore and therefore rely on a combination of meats and vegetables.
It is very rare to see this. Vegetables provide so many different nutrients including vitamins, minerals, digestive enzymes, co-enzymes, fiber, and more. Raw, grated vegetables are necessary to any pet's diet. The vegetables need to be grated or juiced in order for the carnivore's gut to digest the nutrients to the fullest. This assures proper assimilation of all nutrients within the food your pet eats.
