Actually I will give more factors if it may shed some light as to why she's being shy to feed:

-I've had her for almost 3 weeks and she is 3 months old
-Her thermostat reads between 82-90
-Her humidity is at 50% most of the time, sometimes higher
-I have warmed her food in warm water, then tried hot water (not too hot of course), tried dipping the head only, and whole body of small mouse. She showed a LOT of interest in the mouse after dipping the head in hot water. She struck multiple times, either missing or not actually biting onto the mouse.
-Left the mouse for her at the entrance to her hide, no interest at all
-Out during the day a LOT, constantly trying to climb....I chock it up to curious of her new home.
-Has only been handled once since receiving her
