My Hadrurus Arizonesis is quite active. She never stops digging! The guys
at the pet store said this is a female and pregent, but I don't know about
how much I trust ... well you know... For now, she, works. She is really
fat, so maybe she is.
I have her in a medium sized round Kritter Keeper with about 4 inches
of sand. There is a small plastic container with a sponge in it for water,
and half of a toilet paper roll buried in the sand. She actually likes
the roll. I've tried a lot of things to simulate a borrow, but all has
failed until this.
