My moms cat, Mia (who used to be my cat when I lived with her) is also obsessed with heads, but in a different way...she does not like to sleep on them as much as lick, and give gentle love bites to them. We have never figured out her obsession. She's had the obsession since she was a little kitten. It's a strange one. We'll be sitting on the couch, she will walk the top/back of it, and get behind us and begin "eating the hair" on our heads, licking it, soaking it with cat spit, and an occational gentle bite.

What's up with that?
