Gecko, A reptile inharited from the dinosaurs, part of the lizard family, the most common found gecko in a house would be a Leopard Gecko, Leopard Geckos get their name from their skin, they have the leopard style on their rough skin. Like most geckos they keep their food instead of releasing it, infact you would rarely see a gecko have wast in their cage. Geckos have eyes sorta between the side of their head and where people have their eyes, they are placed that make them face streight.
