Some snake enclosures in this building are subpar, and that Chinese Alligator/turtle exhibit is absurd. Natural substrate is a small step to make the animals' lives better, which I appreciate, but it's still too small IMO.
Here's just a break down of it if you'd like.
Great/good enough: Gaboon Viper, Blue Tree Monitor, Green Tree Python, Madagascar Giant Day Gecko, Yucatan Neotropical Rattlesnake, Razo Island Skink, Pancake Tortoise, African Fat-tailed Gecko, California Kingsnake, King Cobra, Diamondback/Mexican Rattlesnake, Caatinga Lancehead, Beaded Lizard, Whiptail Lizard, Mamba, Milk Frog, Spotted Salamander, Cave Salamander, Ornate Monitor, Galapagos Tortoise.
Could use some work: Dumeril's Ground Boa, Nelson's Milksnake, Terciopelo, Brazil's Lancehead, Black Rat Snake, Rainbow Boa, African Puff Adder, Angolan Python, Aruba Island Rattlesnake, Black Milk Snake.
Work: Chinese alligator (I say this mainly because other people say so but I don't find it as appalling as others do)
