Dozens of companies make natural pet food of varied ingredients. The Pet Food Committee of the Association of American Feed Control Officials define natural pet foods as being derived from natural food sources and not processed with chemicals. Some natural pet foods can also contain ingredients such as grain that may not be suitable for all pets. Reading labels on pet food before purchase can clarify the product's "all natural" status.
