pet food, another scam??????

not sure how accurate this is, but i am getting the impression that the pet food we buy is all the same-------they just sell to different groups and they put on their own labels and charge whatever??????of course as usual in this america of today, the truth is a very illusive thing-----does anyone know for sure??and is this same deception a part of everything ???all is marketing, marketing just like our political leaders----so we truly are the lemmings with our little plastic cards, shopping and smiling while being screwed by almost everyone----------lopez pissed again
