Ima put this nicely. I said from what I heard. Now answer this for me hot shot yes or no will a snake not be stressed if it's eyes are blue and it's about to shed and your handling it yes it will be stressed (some might some might not) yes is the answer.
Now will a stressed snake that keeps trying to bite you, because you are stressing it out and it refuses to eat an may not eat until it dies and not everyone knows how to tube/force feed(anyways it may just puke it up) so back up
So is it possible that a snake may die from stress I believe so
