BLUE TONGUE SKINKS

I'm looking to upgrade my girl's enclosure from the 40 gallon breeder that she's currently in. I'm planning on 2'x4' (61cmx122cm) of floor space but I'm not sure about the height. In an attempt to determine the appropriate height I have two questions:

Question #1 - Will blueys actually burrow if given the opportunity? Jean only has about 4" (10cm) of substrate so she can't form an actual tunnel, but of course she likes to dig in it sometimes. I'm happy to give her more if she's likely to use it, but if she's just as happy with this depth then I don't really see any reason to change it.

Question #2 - How much do your skinks climb? I know that as a species they're semi-fossorial, and therefore would presumably climb as little as possible. But when she's not being a potato Jean likes to climb on the half log in her tank, tries to climb up the sides, and has even done her best to climb some of the sturdier plants I've had in there (it's bioactive. And don't worry, I make sure any plants I put in are safe). But she's almost two years old, and she did all of this more when she was younger - is it something they only do when they're smaller/lighter?

Thanks in advance!

Hello there. So I always recommend for skinks an enclosure of at least 4 ft. Ideally 6ft of floor space is the best. However, my personal skinks are in 4 by 2 by 2 and are doing just fantastic. For height I wouldn't go lower than 18 inches. Skinks will climb the walls of their enclosures, and if given the opportunity to push off a lid they will try and will escape. As for burrowing,...they live for burrowing and digging under their substrate. I would provide at least 4-6 inches for them to have a good burrowing experience. I hope that helps.

That's very helpful, thank you!
