LOL...cute pics!
My kitties do the same thing except with the coffee table. The bottom of my coffee table has a bunch of wooden slats to hold magazines etc..(nothing they can catch their head in, but big enough to fit paws through) and it's no fun unless the mice are in between the wooden slats getting batted around.

I know what you mean about doors being shut. I had to start shutting my bedroom door when I'd leave for work....because one day I came home and there were no kittens greeting me. I found them all shut in the bedroom and had no idea how that hapenned...until..I saw Scout playing and watched him bat the door shut! Silly kitty. He'd close the door on himself then meow because he couldn't get out!
