Hi,
It's possible she hasn't settled down completely yet - or you could simply be doing the "zombie mouse dance" the wrong way in her opinion.![]()
Since it's F/T you can certainly try leaving it in her enclosure over night to see if she eats in the dead of night.
We generally try not to panic unitl they start losing weight.
Just do the best you can to help her relax and settle into her new environment and feel safe and secure.
Also asking the P.O. to describe how he thawed, prescented and offered the prey might help spot anything you are doing differently.
