I believe in giving an animal every chance possible to live. Doesn't matter if the snake has one eye, no eyes, kinks--whatever. It's not the snake's fault it's deformed.

Now, if the deformity is severely interfering with the snake's quality of life, then yes, humane euthanization is necessary. I do not wish any animal to suffer just because I want it to survive.

And no, putting it in the freezer is not a humane way of euthanizing a reptile. Reptiles take much longer to die in the freezer than mammals due to their slower metabolism. I would never want to make a reptile suffer like that.

Also, I don't think severe deformities should be bred and/or sold. If I were to breed some pythons and find that one or both of the parents were passing on deformities, I would figure out which parent it is and stop breeding that snake, and I would either keep the deformed offspring or give them to loving homes as pets. We, as breeders, do have a responsibility for passing on only the most healthy of snakes as future breeders.
