So can you? Just an idea, its cheap,and im talking about the one without any additives or pesticides.
Sand sounds okay, the only thing about it is if you don't find the eggs soon enough then they might dehydrate. . . Maybe if you mix the sand with the jungle mix? or vermiculite (which is really cheap) If you are suspecting your lizard to lay eggs you should put a lay box just in case. You don't have to put her in the lay box, just make the box accessible to the lizard. . . She may just lay them in her cage. . . My gecko did that even though it had a lay box.
