So my female '09 normal is not eating at all. I know, winter fast... But she ate for me after the first week I got her. Now, one month later, nothing. I'm trying to feed her right now, and I offered her a white weanling rat this time, as opposed to a black one. And she seemed real interested in it, poking her nose at it for a good 15 minutes, me holding it the whole time. Now, she's just not interested in it at all. So I'm leaving the rat in there by herself for 15 min to see if she takes to it.

My temps are:
UTH 90F
cold side 75F
Humidity 60%

What am I doing wrong? She's also losing weight. Since I got her, she's lost 40g.
