It's very unhealthy and unnecessary for you to feed your leopard gecko mice. Even pinky mice (newborns) are hard to digest. They are also very fattening, and an overweight leopard gecko will usually have a shorten life span. You may think it is cool to feed your gecko baby mice, and for some species of lizards it is an important part of their diet; but, for leopard geckos, it can cause serious harm, and even death. I would never recommend it. I have worked at several exotic pet stores, and this is what my experience has taught me.
