I was watching a documentary on the pet food industry and I was horrified to learn of the practices employed by the various companies. CRUEL animal testing including killing of the test animals, and much, much more. Almost all of them employ extremely deceptive marketing practices and your cat is eating a majority of grains even if meat is listed first on their ingredient labels.
