I have seen them in two exhibits, in the outdoor exhibit and in the large exhibit in the Desert LAIR with the dried cactus.
If they are outside, then they share their exhibit with the Desert Tortoise, Spiny Lizard, Desert Iguana, and I'm not sure if anything else. Inside I don't think they share their exhibit with anything.
This is the outdoor exhibit, and they do not share their indoor exhibit with any other species. I was glad to see the vegetation now growing in the outdoor exhibit.
