that's carefresh in there? I'd thought about that too. It's so light though, The digger might not like that, even if I'd like it better.

About the lizards: from what I understand they have quite a habitat spread, which explains the sometimes contradictory info on them. The two I have are different sub-species and one of them loves the water and the other would be fine with a small drinking bowl.
My beardie doesn't get water in his cage at all.
There's not that much info to be had on them, so i've had to wing it a bit, but they're doing real well, so I must be doing okay by them.
The substrate is a problem. Melissa Kaplan recommends potting soil with orchid bark. Somehow I feel that that's a pain in the butt, but I don't know why I feel that way about it - definitely not from experience.
