A Sensitive Topic

[JMixx]

Maybe this is a silly question... and please remember that I am a herp novice(and don't have any of my own!). How injured does a snake have to be before euthanizing is the best option? I know that some animals have an almost unbelievable ability to heal (sharks, for example) and am wondering about snakes. I would assume that if the tail were damaged, the snake could survive; if the head were badly injured, probably not; but what about in-between? Is a snake run over by a car automatically a "goner," or does it depend on the circumstances? (Also recognizing that this doesn't really take suffering into account; I would guess it is hard to tell how much pain a snake is actually in, although, in my mind, if it is thrashing or coiling in one place I would assume it is suffering.)

I have had the good fortune not to run into this situation, but you just never know...

Oh, and P.S. I have taken barbiturates (prescribed!!) and I cannot imagine a more peaceful way to die. If the drug affects other creatures the way it affects me, I would say it is humane. Euphoria, then sleep...
