Yes, but those are things we choose to do, voluntarily. There's a big difference between that and altering the way a snake is and possibly harming its well being just so we can feel safe handling the animal. If you don't have enough knowledge and experience to handle an intact snake, then you shouldn't have the snake. Period. It's akin to taking out a retic's teeth so it won't injure you if it bites you. Do you also believe it's ok to sew a cobra's mouth shut, as some of the so called "snake charmers" do?
I don't even believe in declawing cats. I have a serious problem altering nature for our own selfish aims.
