She's amazingly soft and as pretty as her bite. I've still got a scar on the back of my hand from working with her. BUT...

Luna is a Virginia Opossum, one of the few marsupials that live in the continental US. What makes a marsupial a marsupial is mainly carrying the young in a pouch on the mother's belly. Kangaroos and koalas are just examples.
