One of my cats has a very odd habit of playing with my hair. He only does it when I am lying down on my front- usually in bed- and he will come up and sit on my back and pick up sections of my hair and pull it through his teeth! He will do it for a little while and then stop and fall asleep (on my back!). I don't think he wants attention as he is not really demanding like that and will happily lie in bed quietly with us all night! I just wondered what he is doing and why?
Any ideas?
