Cats like playing all kinds of different games. The latest viral cat video shows a cat perched in a hammock. When a human walks by wearing a hat, the cat reaches down and swipes the hat off the person’s head.

The cat, named Percy, seems to enjoy this game and his owner encourages it. Hopefully Percy won’t ever get a chance to knock off the hats of total strangers wearing something expensive. Then again, that might make the hat knocking off game even more enjoyable.
