Bobcat and puma exhibits (both of which were mysteriously flooded, forcing animals to sit on a small raised section of earth right next to the viewing fence).
Not really a mystery. Flood irrigation is a common practice in the numerous bermuda lawns in the Phoenix metro area. Now doing it with animals in the exhibit....that's a bit unexpected. At least with cats. Sitatungas happen to be big fans of flood irrigation in my experience.
