I have felt bad for feeding live prey several times. I once had a baby rat that one of my BP's didn't want to eat so I ended up buying baby formula to keep it alive only to end up feeding it off later. I am an owner of a snake that eats rodents so I learned to accept that and move on. I have been very lucky with my newest female BP. She eats f/t prey so I don't have to sit there and watch the process of her eating.
