Funny, Purina whining because Blue Buffalo has chicken byproducts in its pet foods. Purina is one of the biggest purveyors of pet junk food: GMOs, artificial colors & flavors, cereal fillers, and, oh yeah, BYPRODUCTS. BB must be threatening Purina's market share.

I personally would feed BB (and many other brands) long before I would consider Purina. My cats don't get it. My dogs don't get it. My horses don't get it. Even my chickens don't get it. It's junk food.
