a good d substrate is ceramic tile like in floors it is cheap easy to clean and disperses heat well, do your research a lot before getting a leo, they make good easy pets but its best to get it right the first time
yea and it has to be natural sand not that pet store crap
Im kind of a believer in dirt rather then sand and I keep quite a few of my animals in good ol dirt that I got from my back yard
i am lucky and my dirt here is bright red but I like it its a low dust level packs down extremely well and hold a burrow good
