My female hasn't eattin since Nov 17th. Issue?

Like the name says, I have a 2010 female that has stopped eatting, her husbandry is perfect, she just did her first full shed.(we switched from glass tanks to tubs). Anyways, she last ate Nov. 17th, it was a small rat. We always weigh the day before feeding, so on the 16th she was 800gr. she ate and had no problem. Since then however we have offered food once a week at our normal feeding day and she refuses. We had been feeding live, but when we noticed she had become very head shy and seemed to fear the food I tried to change her to f/t, pk, smaller rats, mice, and still she refuses. I need to know what I can do to get her to eat. Shes down to 687gr and I'm starting to feel like shes lost to much. She does not look saggy or anything so I'm lost. Thanks in advance for the advice.:confused:

14 percent weight lose. Not too drastic.
My male went 7/8 months.

Chances are she'll eat when she wants to., just keep offering. Or wait longer between feedings.

I will bet your room has gotten a lot colder in November and that maybe why she has stopped. Also many females will stop feeding at the 800-900 gram mark for a while. Not sure why they do this(maybe puberty, lol) but it is somewhat common and many breeders do complain about it, myself included.

Hmm, how interesting. I hadn't heard that females go off feed at that weight. I wonder why? What interesting animals...
