I would guess this is one of the future leopard exhibit. If I'm correct this was originally housing a pair of brown hyenas in a smaller exhibit (That additional part on the left are likely extension of the exhibit).
While this seems to be still under development, how does such an open exhibit suitable for leopards?
@Rizz Carlton It's going to be a poor exhibit if Leopards do make their way here, but for a Serval it would probably be the best in Southeast Asia as I saw many terrible Serval enclosures on my August trip. One cool thing about this image is that I was able to go inside the exhibit to take the photo as there's currently construction going on and there's a big open section that will eventually have a pane of glass.
