We've had A LOT of cats when I was growing up, and some of them of done really weird things. One cat liked squishing behind the refrigerator and sleeping between the wall and the base. Another cat stole EVERYTHING (pens, medicine bottles, toys, trash, markers, scissors, etc) and hid it under our china cabinet. We only found out after we had moved the cabinet to clean. My current cat hides in our laundry room a lot, and likes to sleep behind the washing machine and or on top of the shelves for the laundry baskets. Also, my friends cat freaks out if you sit on the floor and laugh at the same time. He comes over and smacks you like crazy until you either get up or stop laughing, or both.
