Most of my female BPs (except one) have super strong feeding responses but they know what food looks like. Like I said, I have two that feed live and even they do not confuse me for a rat/mouse/ASF. Opening a cage for some does not mean feeding time. However, for my BCI male, he is ready for food the second I open his cage but he knows there is no food if reach in and touch him. He has also never mistaken me for food.
