Oh my God -- my cat LOVES to lick my hair! And I hate it! She gets this glazed over look in her eyes and licks and licks and licks. So annoying. It is hard to snap her out of it. She does it at night while lying on my pillow, but also from the back of the couch or armchair. Thankfully she has never attempted this on anyone besides my husband and me. She is a plain old domestic shorthair. We have two from the same litter who have been together since they were born, and the other one has never been interested in hair. Cats are so funny!!
