If I toss something in the air toward my cat for her to play with, she'll shake her head from side to side very fast. She look possessed. She also loves to mark things by rubbing her face on them like most cats, but she uses her gum line and a single tooth to do so. She also loves it when I give her a brush to mark things up with. She half eats it or something. Here is an video of me doing that in my old apartment.
