The thing that keeps mules from reproducing is that horses and donkeys have different numbers of chromosomes, thus messing up the germ line cells in mules. In snakes, for whatever reason, closely related species seem to have the same number of chromsomes, so if it's possible for them to hybridize, the hybrids are fertile. I don't think I've heard of any infertile snake hybrids. Maybe there's something about mammal cells and evolution that makes their chromosomes change number more frequently, I'm not sure.
