My personal cat, Wicket, used to wake me up by patting me on the cheek with his paw. He'd go.. pat pat pat. Pause. Pat pat pat. Pause. Pat pat pat. And if you didn't respond the fourth time he would repeat this with his claws out so you were just gently stabbed awake.
He also used to wake me up by stabbing his nose into my eye, like diving his face into mine. He's locked out of my room now but I had this for years
