Hera used to be very picky about what she wanted to eat. At first she would take F/T mice but would occasionally refuse. I could never get her to take rats. And then about a month ago she stopped caring about F/T completely. So we switched her to Live mice and she now never refuses.

I know that the mice CAN bite her but I check the mice carefully and if they seem eager to bite I will do a fast P/K and she will usually take them.
