one of my rosys shed last night... because they require such low humididty here is what i do... take a smaller tupperware or critter keeper... some thing with air holes in it, and line the bottom with warm paper towels or wash rags or hand towels or what ever. put a hide in the tub and then put soem crumpled up paper towels or a fairly wet spnge or something in there for her to rub up against. leave her in there for a few hours and check. i left mine in there over night because she wasnt done before i went to bed, and this morning it all came off in one piece. remove her right when you see she is done. and also make sure that you have a heat source for her... as the wet towels will get mighty cold. this has workd EVERY time for me as it is much easier to maintain humidity in a much smaller container. let me know if it works!
