There is a HUGE difference between HEALTHY by-products and the by-products in commercial pet foods.
HEALTHY by-products are things like liver, kidneys, sweetbreads, tripe, gizzards, heart, lungs.
These are NOT the kinds of 'by-products' found in cheap pet foods. THOSE by-products are things like beaks, feet/hooves, digest, intestines, horns, embryos, tallow, sinew, etc. Also processed grain fragments and anything else that would otherwise provide no nutritional value or would be considered inedible on it's on face value or are waste products created as a result of processing another product.
The ONLY time a product with by-products is safe to buy is if it distinctly says .. Beef/chicken/lamb/pork by-products ( ORGAN MEATS ONLY ). PERIOD. Those are actually HEALTHY, DESIRABLE ingredients. Unfortunately very very few companies choose to use quality by-products and choose WASTE products as their by-products.
