you have long hair? My cat likes to groom people but I'm the only one with long hair. If she grooms me it gets stuck on the spikey bits of her tongue and she then tries to chew it loose. It's not intentionally trying to eat it. there's not much you can do if you don't want to cut your hair shirt but try and keep her from doing it and/or pull your hair from her mouth so it doesn't stay stuck and get chewed. If doing it while your sleeping wear your hair pulled back in a pony tail or other form of protection for it.
