This one is professionally ugly and the first time I see lemurs in such a setting, normally macaques and baboons are the monkeys to get such an enclosure....
@lintworm I absolutely agree! This looks hideous for lemurs! Maybe the zoo could move them to an empty area near the Islands section, name it "Lemur Camp" and focus on different settings for the lemurs, all in either walk-through exhibits replicating a spiny forest, and/or separate enclosures for the Masoala forest. As for what to do with this abomination, I'd say demolish it fully.
