I recently got a male and a female ball python. Last night, I fed my male and within seconds he had killed the mouse and started the whole feeding process. My female, however, can't catch the mouse. I have the smallest mouse I can possibly get, and its live which its previous owner always fed her. At this point, I'm literally dangling her meal in front of her face by the tail, and she still snaps at it but misses. What can I do to help her?
