I am going to have to side with stefan on this one... I will not freeze snakes. Every time i ever froze a snake that was alert enough to still move around, I always found it in the freezer in the most awful contortions. That to me suggests pain, whether conscious or not. I have and always will use decapitation/blunt head trauma. Sure its hard to do but honestly I have learned to separate feelings with what needs to be done VERY well. At times I am almost scared of myself in how detached to any emotion I can be. The quickest death is one they never see coming. Babies I usually stun, decapitate with a fresh razor blade and immediately smash the head with a hammer. If you don't destroy the brain immediately, the snake's head WILL live for several minutes because their brains can go a considerable amount of time without oxygen. With a larger one I usually take a hammer to the center of the head on a hard surface and then decapitate. Larger snakes are a little harder to stun successfully and you may end up prolonging the incident longer than it needs to be. This is not just for the occasional pet snake that needed to be put down, I also do this for any wild snake that is too seriously injured by a lawnmower or car to be saved... and I have found two with unmistakable deadly blockages in the gut that were already on their way out. It's hard to do and sometimes you'll cry, but a blow to the head is quick and painless. This is instantaneous, doesn't-ever-know-what-hit-them death.
