No, it has been a LOOONG time since they did that - almost 20 years. For the last decade or so they have had a single gray fox in cat canyon in the former jaguarundi exhibit. It just sits on one ledge in the same spot without moving all the time - they have a blanket for it there and it literally never moves.
A few years ago they retired the two bears they had on exhibit and renovated the exhibit to combine the two very small night quarters into one larger quarters. They also did some minor modifications to the main exhibit, but I cannot see any difference. Anyway, they are now set up to have only one black bear in the display exhibit.
