I was at my local exotic pet store today and they got in a white leopard gecko who seems a little special. He's always got his head tilted to the left, he walks to the left, leans to the left, and sometimes tips over. Pet store isn't sure what's wrong with him and I really want to take him home. Any idea what the problem could be? I know this is all very vague, I just saw him at the store today and fell for him. I'm pretty sure I'm going to pick him up later this week, any tips on caring for a less capable gecko?
