"Reptile Carpet" is NOT the best thing to have any reptile on, it holds bacterial, it doesn't allow for burrowing, and it retains zero humidity, if it becomes wet and saturated it can mold. A healthy Bio-Active style soil mix that is a little on the desert side as far as moisture works great. I don't like hearing "its the easiest to clean" when it comes to substrates for lizards, lizards burrow, they dig, they don't just sit.
