So for some reason my bp refuses amy rats but will take mice. So should I just keep feeding her mice, or keep trying rats until she takes? She was taking rats for the longest time but then she stopped eating. Tried everything for two months strait with no success. Then tried a mouse, and she took. Did mice for three weeks, and back to a rat that she refused. So since then she has refuted rats and only take mice. I give her two mice in a weeks time.
