They are very hard to remove. Every time I would get the knife blade under a foot and release the foot, I would place a small piece of plain paper between the foot and the sticky surface so that it would not stick again. I did this foot-by-foot, then an inch of the tail at a time, and then - well you understand. Finally I had ruined the sticky surface with so many pieces of paper but the lizard was freed that way. Being a dentist might have helped. I am used to working in small spaces and handling instruments.
