cats

My cat goes crazy for stickers/labels that I've folded over. I flick them across the room and he goes nuts chasing after them. Can't think of anything they would hunt in the wild that looks similar.

I think it's less about prey and more about play, so to speak. Keeping in mind that my cat is a total dumbass orange cat with naught a single brain cell, once he loses track of it, he loses interest.
