Hi, I am Stephanie, A pet nutritionist
What you are probably talking about by products
Chicken By products contain heads feet and intestines
So, stay away from that, and you are good (Just know there are many types of by products, chicken, beef, etcif you see MEAT by products, or ANIMAL by products, you don't even know the source of the by product.
Nutro products, can be found in larger pet supply stores, like PetSmart, Petco, as well as smaller,independent stores
Nutro usue HUMAN GRADE foodmeaning everything in the bag, is suitable for human consumption.
Nutro also is 100% guaranteed! Guaranteed to improve skin & coat, guaranteed to reduce shedding, guaranteed for less "waste" AND guaranteed for great taste! Meaning if your pet doesn't like it, you can return it or full refund!
Also,Nutro is vet approved, and has all the Omega 6 & 3 for optimum health. It is double inspected, and safe!
Here is the official definition as per the AAFCO (The pet food version of the FDA) I have also added the link below:
Definition: Chicken by-product meal consists of the ground, rendered, clean parts of the carcass of slaughtered chicken, such as necks, feet, undeveloped eggs and intestines, exclusive of feathers, except in such amounts as might occur unavoidable in good processing practice.
Examples: Chicken by-product meal is considered an inferior source of protein for cats. Although cats may eat a certain amount of by-products "in the wild," the most nutritious commercial cat foods will show a named meat, such as "chicken" as the first ingredient, rather than "chicken by-product meal."
