Meet Swiss, a tiny Ringtail Possum orphan being looked after by her new surrogate mum and elephant Keeper Bobby-Jo at Australia's Taronga Zoo. Swiss and her sister Miss both came in to care after a good Samaritan found them. Vets at Taronga’s Wildlife Hospital think Swiss fractured her wrist when her mother died, but with a tiny splint on her wrist, the two are doing well in Bobby-Jo’s care. Follow Swiss and other Taronga Zoo critters on their Facebook page.

In the wild, Ringtail Possums live in communal nests where they sleep by day and socialize by night.
