Oo thats a good one! After the holiday season when boxes are bigger and bountiful I often have to play Schrödingers boxes and try to guess if its safe to move and break a box down or if there's a cat in it.

My go to prank when people are around involves my big orange floof I call Ra. I carried him all around in the palm of my hand when he was kitten and well that didn't really change once he got bigger other than using 2 hands sometimes. He basically sits his front legs in one hand and rear in the other like a pampered loaf. He's got enough floof to hide my hands though so anytime I'd hear someone get home or approaching from around a corner I'd hide behind the corner and stick him out just far enough so it looks like he's floating in mid air. My sister started calling him hover cat.
