thank you so much for the prompt replies. I will definately not give her any crickets, thank god for all you guys out there. I knew I came to the right place for advice.
in regards to her living conditions, i dont believe there is a problem there but here's a little info as follows:
she is housed in a 40 gallon tank which she has been in about 5 months now. Prior to this large tank she was in only a 20 gallon. At first she was a bit intimidated by the larger tank, but she got used to it, and I could tell she enjoyed the extra space. Her tank is lined with papertowel on the bottom, and I use aspen shavings as substrate. Temps are perfect, 75 on cool side, and just about 85 on the warm side. I am also using UTH. I also feed her in her old 20 gallon, which has become her feeding tank. I buy her frozen adult mice from a pet store in Calgary, AB. and she is offered a f/t mouse every 7-10 days. When I ran out of mice last, I decided to buy some frozen mice from the new pet store that opened in town here (i decided to just buy 5 as it was a new place and i wasnt sure if they'd be different than the ones I usually buy or what). When it came time to feed, she refused. She smelled the mouse and backed off. A week later, I left a mouse on some paper towel in her tank overnight, once again she did not eat. All 5 of the mice I bought she did not eat. I thought maybe it was the mice, like maybe the new petstore had thawed/re-freezed the mice too much. who knows. so I went to Calgary (where I originally buy the mice) and bought a whole bunch of adult mice and 2 hoppers. I left a f/t hopper in her tank, thinking she might need a smaller meal after being off food for so long, and she did not eat that either. Since then, Ive offered her another hopper, and I even made a slit in its head to draw more of a scent, but again, she did not eat. She is becoming quite dark in color, and quite skinny. The only time she has gone off food in the past is during the entire shed process. She has never been an eater then, and she is definatley not about to shed either. She is not very active since she's been off food, and is generally hiding under the substrate. When she is active and well, I almost always see her cute little head poking out. PLease any advice will help, I dont want to lose her!
