Why my desk is so clean

I regularly come home to a very clean desk... which is not the way I left it. My floor, however, is covered in random papers, receipts, money, USB sticks, and everything else that used to be on my desk. I finally catch the culprit red-pawed, as Shorty carefully sends each item tumbling to the ground followed by a blank stare. Do you have a housekeeper-cat too? Why do you think they do it?
