you should not use sand for savannahs, use a good amount of dirt that they can dig into. top soil from loews or home depot or actually creek mud works well if you have a lot of clay in the soil around your area. sand doesnt hold moisture well, and savannah monitors in the wild live in grassy fields, not sandy deserts. good luck
