Jungle carpet shedding.... HELP

[sfournier]

I have a 4 year old, 7 foot, female jungle carpet python. Shes in a 75 gallon tank with a huge water dish. Her bedding is coconut fiber and she has drift wood along her cage. Humidity is 65-70 temp is 85.
Ive never had this problem with her before. But she went into blue about a month and a half ago and never shed. I fed her a rat last week and she took it no problem. But shes wheezing because she wont shed. Its not because of a respiratory problem! (My corn did this same thing one year, and after several vet visits we finally got her to shed a thick shed in one piece. Weird.) But anyways, I now put her in a plastic tub with air holes, a water dish and coconut fiber bedding so the humidity is really high and a heating pad under her. Is there anything else i can do to aid her? Or encourage her to shed?
