Sounds like Sterling when he was younger. I thought he'd never let me sleep. He would wake me up by licking my face and into my hair and then the hair would be too long for him to handle so he'd chew......very annoying. He wanted to play "fetch. (yes, in the middle of the night). Or just wanted attention (the time we are asleep must seem like an awfully long time for a cat to not interact with us). The only way I got him to stop was to actually get up, most likely go into the bathroom and give him a few moments of special attention. He'd then settle down for the rest of the night. Thankfull, he out grew this. And I think I miss his neediness.
