I think what Nativeson means is, it's not necessarily natural to them. Playsand is not natural to Leopards. "The native habitat of the leopard gecko is the rocky, dry grassland and desert regions of south-Asian Afghanistan, Pakistan, north-west India, and parts of Iran." (Wikipedia) I'm sure I can find this same information in other articles as well. Wiki was just a quick and easy place for the information. So, it is only Partially sandy. It is mostly Rocks and Grassland (which the gras is probably growing out of sand). You're set up looks pretty close to naturalistic as you can get with out Cutting out a piece of Pakistan. I'm with you, I like using sand in my enclosures and make them as naturalistic as I can. I have some major plans for my next enclosures and yes, it'll include some sand or moldable sand.
