how all of that kitty litter gets on the floor outside the litter box?

First, a little background. We recently moved the litter boxes from the guest bedroom (future nursery) to the computer room. I just sat and watched Chloe in mid-catfit jump repeatedly in and out of a covered litterbox to pounce on a ribbon on the floor. I have to say, it was pretty amusing.

Now I need a broom...
