Annoying habbit of pets?

Mabel

Hermann does many annoying things.

He's decided that when the heating comes on in the morning, it's breakfast time, and will bat at my face for hours.
He's obsessed with the rubber ring seal in our coffee grinder - if it's actually possible to get it, he will find a way, and then make a racket playing with it.
You can't leave him alone in a room with a bag of Dreamies without him tearing the entire thing apart.
Last night he stood on my chest for ages (ouch).
