@Jarne I would expect more from a zoo that has such a good reputation. How difficult would it be to add some branches to allow them to climb a little? It still would be a bit small, but better than nothing.
@red river hog It's tiny for such a large species (being able to stretch out has been shown to be beneficial for the health of snakes, so a length similar to the snake is a decent minimum), and things like a pool, decent cover and climbing options are all lacking. The only good thing is that they didn't put two in this box.
