I am not really a fan of the idea. If you want a venomous animal, that is fine, just learn how to handle one properly. No need to butcher a top tier predator for your own contentment. There is a reason they sit atop their respective food chains and we need to respect that.

And, who are the "most" that says it does not cause the animal distress? To do it completely requires extensive surgery that very few folks are truly qualified to do. And, if the animal cannot kill prey, and will not convert to p/k or f/t, there is a whole other issue.
