Crazy Cat!

Me:  Does he do this every night?
Mason:  What?
Me:  Run around like a lunatic.
Mason:  Only about 50 times and they he gets tired and goes to sleep.

We are referring to our cat Zippo running laps across the whole 3rd floor and jumping up against the walls.  Levi and I hear this a lot at night and always thought it was the boys.  We have yelled upstairs several times "What are you doing up there?" and the boys always say "Nothing".  Guess we blamed them for something the crazy cat was doing.
