Not sure if someone made a topic before, but I think we need a topic of non-exhibit animals. Kinkajou, various macaws, many of the "pet-store" animals (ferrets, leopard geckos, ball pythons, bearded dragons, guinea pig, etc.), serval, fennec fox, various birds of prey, and even tenrecs I've heard. Cockatoos, junglefowl (and chickens themselves), and I've heard of even a red panda being used as outreach animals. How are they usually housed? I know zoos usually keep them in exhibits not really "fashionable" or "natural" in plain peoples' guests faces, but in my opinion I think it's quite interesting to see. Toledo IIRC has an Education Animal Barn, where certain education animals are viewed even in their enclosures (which usually suit more of the animals than the appeal of the guests), and some zoos and aquaria even have special rotation enclosures, from Seaworld San Diego's rather lush, to other zoos having "themes" to surrounding enclosures (from simple lawns to even barn-themed enclosures).
