Okay, while your all on this "Petfood Eating" kick.... When I was a young kid my mother (Like almost ALL mothers of the '70's ) went on a Tupperware binge. EVERYTHING in our kitchen was put into Tupperware! Including my breakfast ceral and the Meow Mix.... Long story short at 6AM Meow Mix DOES NOT taste good... even with milk on it!

Moral: If you have kids, for the sake of their budding taste buds, PLEASE label your Tupperware.
