I spent the night at my cousin's house a handful of years ago. I have no idea when the house was built but I'd say around 1900 or so. Her then 7 year old son had been complaining for awhile that the "the cat" stole his covers at night. I stayed in his room as he was with his father. I woke up several times to someone jumping on the bed...I was, of course, alone in the room. On the third or fourth time I said loudly 'Stop it, I've had enough' and it didn't happen again the rest of the night.
