What is a Gecko?

Geckos  are lizards that are small enough to fit in the palm of your hand. They come in many shapes and sizes from leopard geckos (that can grow up to five inches long) to monitor lizards as big as two feet long!

There are many gecko species (over 1600 species) but Leopard Gecko is the most common all over the western world. As insectivores, geckos will feed happily on cockroaches.

But as pets, it can be necessary to supplement their diet with a mealworm or roach every once in a while if you want them to grow up healthy!
