@DelacoursLangur There are four similar cages total. In theory the monkeys can have access to all at the same time but when I was there they only had access to two. I don't know if the cages are new (I think they may of indeed been off-display cages at one point) but the monkeys had just moved in when I visited. They use to have one single much larger habitat but it was demolished to make way for the upcoming Madagascar area. I love when zoos innovate but I don't think it should be at the expense of animals already living there.
