New adult female feeding strikes on me - how to judge hunger/weight?

[Timelugia]

This is after another strike a week ago, where she grabbed and held onto my pectoral after nosing underneath the open zipper of my sweatshirt. That also seemed to be feeding behavior.

Do you have any small animals she could be smelling on you?

Two adult mice isn't enough. My guess is that she's probably long but skinny. I have a 6 year old normal female and she's 2500 grams. I wouldn't OVER feed her. Maybe start out with a medium size rat and build from there. I would image that her stomach isn't used to digesting a 140g rat so go smaller and work your way up. Give her 2 hides if possible (one on each end).

She has two identical hides, the black plastic type, about 8"x12" footprint. She's uses them often, but also ends up lifting them up and being half in and half out as well. I'm considering making them heavier.

I do have cats, but I've been careful to wash well before handling her. The house of course smells like cats I assume.

How do I judge skinny vs heavy? I know if she's obese she'll have the valley above her spine, but how do I tell slightly underweight?
