However I have had the substrate in my Leopard Gecko's cage for over 2 months and he has not begun to burrow. I have felt the substrate and it feels far to hard for him to burrow in. I did take the liberty to make my own burrows for him and left a good section for him to burrow in, but nothing. I prepared the clay just as the package says. I think that this is great if you want your reptile to live on rock. I, personally am going to switch back to using play sand as I did before.   1   Non User
