They have 3 enclosures, one off-show, a small on-show den and a larger one (where this photo was taken). I arrived in time in time for the 11 am keeper's talk, and the cats were fed during this (with a small group on the carnivore experience assisting). Both cats were easy to see at that time, but things were a bit crowded and I watched the tayra next door instead. I took this photo just after the other people left.
It's definitely not a dark enclosure. There are large windows on two sides, and the exhibit is not in a nocturnal house like the one at Bristol, for example.
Although I don't have a shot of the entire exhibit, the attached photo shows a part of the main enclosure, showing some of the windows and the (outdoor) pathway beyond.
