Then i fed her mice and she went for it.
Make sure your mouse is heated up enough. If you squeeze the mouse's head/body and it still feels cold let it sit out or sit in some warm water for a little longer.
I had problems with my snake at first, temperature wise, the mouse felt warm to me but it wasnt enough for her. So id warm it up a lil more and she'd eat it right away.
Also it could be the size of the mouse/rat you could be feeding her too big a size?
