Actually, I have two girls who haven't fed yet since I've gotten them. The last time they ate was 9/21, and they were shipped to me on 9/24. I know that it is common for them to go off feeding for a while, but the two that haven't eaten yet had shown response to live mice. The other girl that came with them ate two weaner mice. So, wait another 5-7 days and try again? These are live mice, they were eating F/T, but I wanted to entice them into eating with the lives, then using F/T after they settled in and started eating regularly.
