Every-time I go over my in-laws house, my favorite thing is to see their cat Johann. Since cats are more naturally nocturnal, he's more active during the evening. I always get tickled when we play a game where he looks at me and then I hide behind something and he can't see my eyes. It drives him crazy. He'll often try to hit me with his paw as I go back and forth between stuff. I assume he thinks it's fun.
