Get well soon, Swiss!
The young possum, along with her sister Miss, was discovered in her dead mother’s pouch and taken to Sydney’s Taronga Zoo, where zookeeper Bobby-Jo Clow noticed that Swiss had a swollen arm.
This extra-small, 2-oz. ringtail possum had a fracture in her wrist and was given a 2-cm.-long splint to help the bone stay in place and heal.
