Soak her in lukewarm water for about 10-15 mins. Make the water just deep enough so that it comes about halfway up her body. Then get a towel or large wash cloth and wet it with lukewarm water. Make a circle with your hand and the towel and let her crawl through it. This should help the stuck shed come off. May have to do it a couple times.

Remember that human body temp is 98-something so anything that feels really warm to you is too warm for her.
