I have a kitten, Angel, who wakes me up at 4.30 each morning by licking several layers of skin off my face.
Cheaper and probably just as effective, although a little....rough...and I have to cover my mouth so I don't get my lips skinned.
His favourite spots are my nose, eyebrows and chin.
I can't stand it for long, I have to get up and wash my face off.
He's grown a bit, weighs a whole kilo now.
