Query: Do your research, please!

I am continually surprised that this food is rated as one of the best out there. Look at the ingredients. Cats are obligate carnivores, they require meat, not corn, not wheat, not brewer's rice, not "powdered cellulose" or "soybean mill run." None of the rest of these awful ingredients. Where is the meat in this food?Please do your research & investigate the ingredients in any pet food you plan to purchase. Your pet's health depends on your knowledge!
