One of the great things about having a Leopard Gecko is that they are extremely clean. My Gecko is cleaner than my Cats.

She goes to the bathroom in the same spot in her habitat, and due to the semiarid setup by the time I see it in the morning it is already dried up and easy to just pick up and take out.

And its not just her, many Leopard Gecko Keepers remark on how clean and tidy their Geckos are.

African Fat-Tailed Geckos are also like this btw.
