We have just opened a new spot-tailed quoll exhibit, containing 1.1 animals. Features include a 3m x 2m glass viewing window, and a sliding divider which can be used to easily cut the enclosure in half for animal management reasons. The male is usually out during the day, often climbing a tree adjacent to the window. He actually seems to play, swinging 360 deg around a branch at times. Pictures in the gallery.
You have to tag your zoo MRJ, otherwise people won't know where it is! I saw this exhibit under construction, it looked like it would be a great enclosure, and reminded me of some of the smaller aviaries for native birds at Melbourne Zoo and Healesville Sanctuary.
I like this photo: http://www.zoochat.com/385/moonlit-sanctuary-spot-tailed-quoll-3-a-325207/ You can really see the relationship to Tasmanian devils in the head-shape.
