Personally speaking, I've had one neonate Kenyan Sand Boa that passed away a couple of days after birth back in 2008. It did appear to have a slight kink halfway down it's body that may have contributed to it's death, but I really don't know. I've also had 2 stillborns, and two extremely underdeveloped babies that didn't make it over the past two years. What went wrong with these, who knows??? Still hurts to see those little ones come out absolutely perfect looking, but not alive
