We have one bp that eats well with a towel draped over the box and he eats F/T.
Then we have another that just likes alone time with his food, but he makes us nervous as he only goes for live. When he kills his prey he likes to hover around it for 15 minutes or so. If he doesn't eat it within an hour or so then we take it out!
Then our little girl Hathor (the bumblebee) likes a red spot light and someone watching her while she eats. If you take the red spot off her and walk away before she has the mouse half way down she will spit it out and wait till you come back and put the light on her. She eats anything from F/T, Fresh killed, and live, but likes an audiance!
We have found feeding time to be one place where the personality of our snakes really come out!
