My office mascot, Mr. Prime Minister Toulouse le Chat, seems just fine with it.
He's been head butting me to wake me up since he was a wee furr ball. He still does.
I mean, REAL head butting. BAM. BAM. Wake the heck up, dude I'm hungry.
My cat's the exact opposite. She FREQUENTLY hits the snooze button on my alarm clock and goes back to sleep. I've been late for work a couple times because of this.
