Leo sometimes decides to clean my forehead, and when he first came to live with us, if my hair was wet at night, he'd lay on my pillow and groom it and play with it. Thankfully he grew out of that! Claudia likes to play with my hair occasionally, and she has groomed my arms before. The other two don't groom us, but Bailey grooms Leila & Claudia, Leila grooms herself. Leo grooms both of the girls and tries to groom Bailey, and Claudia grooms herself and attempts to sometimes play with and groom the boys' tails.
