Does anyone have any suggestions as to how to get my two balls to eat f/t rats. They have been eating f/t mice since I got them 2-3 yrs ago. The female ate a small rat the first time I offered it 2 weeks ago but has since refused. The male doesn't want anything to do with them. I don't really care if they switch completely to rats or not but I bought 30 and would hate for them to go to waste.
