Well I have used jungle mix and cyprus. My Red Tegu much preferred cyprus mulch. That said, I am now using white beach towels. Very easy to clean, she comes out on top and burrows under. You can always see if there is a mess to clean up. We switched to this method after having a mite infestation. We don't know where we picked up the mites, maybe from a mouse? The cage stays spotlessly clean now and she really doesn't seem to mind. When they get dirty, shake em outside and throw them in the laundry with a little bleach. We do the same thing for our Ball Python. I know it doesn't look as cool as a tank full of mulch but you know that your tegu isn't laying in a pile of her own filth.
