Hi Flavia! It's been a while since I've seen you post. I hope all is well with you and all your critters!
I just wanted to add, that Dill does the same thing. I know that they like to be in the highest spot, but rather than climbing up on top of my head, she prefers to be around my neck, and under my hair as well. I'm assuming it's because it's a place to hide, and is the human equivalent of a cover of leaves that she would hide under in a tree.
It's odd though, because she seeks out my hair. Even if she is sitting on the back of the couch, where she is higher than my head, she will climb down onto my shoulder, and burrow her face and then her body in under my hair. Maybe it also has to do with my body heat as well? I'm guessing it would be nice and warm at the back of my neck, under my hair.
I've never noticed any hair in her bowel movements, but I will certainly be more diligent about discouraging her from burrowing into my hair.
