My Simon would do that but I broke him of it. If he was sleeping next to me and I wanted to pet him he would bite my hand. I would say in a stern voice. SIMON, NOOOOOOO, NAUGHTY KITTY, DON'T YOU DO THAT!!!!!!!!!!! Then I would leave him alone for awhile and do it again. He caught on and if he doesn't want me to pet him he will act like he is starting to bite me but it's just a fake-out. Sometimes he will lick me. LOL I always praise him when he does that.
