I use the Damp towele in a dry pillow case trick for stuck sheds works great but I have never heard of a wet pillow case that could casue problems quess I will have to make sure people know not to wet the pillow case. As for the snake I would definatly make sure the people who own the snake get a copy of the care sheet so that they can correct the problem with thier husbandry causing the stress or bad sheds
