Maybe one that's descended from avian ancestors, so her hair is feathers and her teeth are two continuous blades of chitin rather than individual knobs of enamel. I kind of like big, nocturnal eyes that shine in the dark. Maybe a prehensile tail that also aids in communicating emotion?
What about behavior, though? Maybe they'd make cute sounds, chirrups, trills, warbles, purrs, chirrs, etc., or do cute stuff like rubbing up on you if they like you, bringing you food or "practicing" with stuffed animals. Maybe they smell like cinnamon when they're aroused.
