Why do cats...

My cat likes to lick my hair and face lots!! When I am in my bed or laying on the couch he likes to circle around my head and then eventually lay accross my face. He will only lay there for a moment then will get up and do the entire routine again! Does anyone know why he does this? He is siamese if that matters.!! Thanks!!

It's his way of "cleaning" you. Cats do that on themselves, other cats and their humans.
