First of all, he loves people food. One time we brought the groceries home and within minutes he had shredded a bag of bagels because he wanted those carbs SO BAD.
He really, really likes to sleep on his back. It's extremely odd.
If he smells something he hates (orange peel, nail polish remover, minty gum) he squints his eyes shut and scrunches his face back. Get that away from me! He thinks we are crazy.
If you throw a sock onto a ceiling fan, he will sit and stare up at it endlessly, waiting for it to fall.
But, if the sock ever does fall, he probably won't give it back. He has a major things for socks and hats and gloves. Especially gloves. Even if your gloves are in your coat pockets that are buttoned shut, he will claw them out, take them to a secret hiding place, and growl and hiss at anyone who comes near.
Oh, also, he's on a diet.
