My cocker Zoe did this and now Paco does this too, I don't know why. It's not like he doesn't have perfectly good food in his dish. Just UCK! I've turned the box around so he can't get it and there's no way he can turn it since he's so small. Now to get the EFO to stop eating the dog's food. He only does it because he's well, *ahem* the Evil Feline Overlord.
