My ball python, Hurly, has always been rather different. I have a picture of him hanging on to my son's wrist upside down, for example. And if he is hanging on to something and decides he wants to go somewhere else, he just lets go and falls. We've learned to keep one hand on him at all times because it's inevitable he's going to let go and fall sooner or later. Someone told me he might have a recessive spider gene that causes him to be so not all there. Is this possible? If so, what is this going to mean for him? Are there any health risks associated with this? He doesn't have a head wobble and the pet store sold him as a normal.
