What is the gecko natural environment like?
In the wild, geckos come from desert environments. But it is not the sandy as many people thought so. Their natural habitat is the rocky desert and grassland. There are rock, hardened clay dirt, and just a little amount of sand in their natural environment. They are not surrounded by any sand dunes.

Geckos tend to swallow their substrate when they eat. This is more often to happen with younger geckos. And when they eat sand it causes the impaction in geckos, the sand will become cement and causes a blockage in the gecko’s intestines.
Even if you feed your gecko with a food bowl, they still try to lick the sand anyway.
