I've been thinking about 4" PVC because it is smooth (easier to push them out). And I could clean it if they wee in it, rather than having to throw it out.
I've got my hatchling with a 2" PVC T-piece that she can lay on top of, which she loves....think it's something to do with the smoothness, but of course when she gets even near 2/3rd's of the diameter I'll toss it and get something different or just bigger.
