Borneo Short-tailed python will not eat

[Kneff1175]

I purchased a 2 yr old BST 2 months ago at a local reptile show. They said she was nice and docile and ate regularly. She was in shed, but aside from that looked very healthy. Since Ive has her she will not eat. Ive tried f/t, live, pre-killed, rats, and mice to no avail. I went back to the show a month later, it comes once a month, and ask what she ate. The young lady said that she was eating african soft fur. Of course no one locally has any and the nearest in 200 miles away. Shouldnt a bst basically eat anything? It has been 2 months since Ive had her and they said she ate maybe 2 weeks before that. She in on cypress, has a litter box filled with water, temp is 87 on hot, 80 on cool. Humidity is kept usually at 70%. She is on a timer for lights, and thermostat, and has a hide/sweat box that I keep with sphangum moss. Her enclosure is 2 1/2 ft by 1 1/2 ft. there are no limbs as she is too big too climb. I try to mimic swampy conditions. I covered the fronts and sides lastnight and the weird thing is she was really in a foul mood this morning. Maybe she couldnt see me coming and I startled her, but she seemed on edge. Usually shes very docile. Almost dogish. I know with BSTs that can change in a heartbeat. I have 7 other different variety snakes and all but her and a rosy boa are eating fine. Should I be worried? It is starting fall here and outside has been really cold and rainy. Could that effect her? There is a window in the sun room where they can see the outside? Im grasping at straws I know. Shes a big girl but how long is too long for a BST. She also has not defecated, but Ive read that BSTs rarely do. She soaks, she burrows, she goes in her hide, when she yawns her mouth is nice and pink. I just dont know. Any help would be appreciated.
