Dear Dr. Baum —
When I got up this morning, both legs on my leopard gecko were broken! What could have caused this, and what can I do? I see his legs are dragging. I just don’t know what could have caused him to break both his legs at the same time. He was just like this when I woke up and he has a small cut on his leg, too! It’s weird.

Obviously, trauma to the back or legs is responsible. The question is, how much trauma did it take? Many reptiles suffer from metabolic bone disease resulting from a diet which is too low in calcium, or in which the dietary calcium cannot be adequately absorbed due to lack of the sunshine vitamin, Vitamin D-1. This deficiency causes the bones to weaken resulting in pathological fractures. You can make sure you are providing enough Vitamin D-1 for your gecko by exposing him to sunlight, and there are also special full light spectrum light bulbs you can install over the terrarium.
