I don't know if this is true for most snakes or not but I've found that my little girl is alway extremely calm during the blue eye phase just before a shed.
I know alot of people have said that they don't hold their snake before shedding because of stress and the whole "might bite because they can't see" thing, but if the snake doesn't seem stressed at all, is there really any harm?
It almost seems like she's falling asleep in my hands.
