when my snake goes blue, i have the humidity up around 85% and higher, and she still hasn't shed in one piece. i've had her since christmas of 2006 and she's shed 3 times already. she's 2ft. and 200g. born summer of '06? (she gets a very small rat every friday) i've even soaked her a couple of times. she generally sheds in anywhere from 5-8 big pieces. is there anything else i can do?
