I only feed mine live. My BP is 5 years old and has always been on a live diet. The previous owners said they tried everything and she just won't touch anything that is pre-killed. I haven't tried to switch to f/t since I made the decision to stick with live anyway. I don't look away for a second when feeding and I'm at the ready to intervene if needed. I kinda feel like that's the gift mother nature gave her and I don't wanna take that away from her. She eats like a fat kid going after cake so I just let her do her thing. That's just my opinion and I know I'm part of the minority. At the end of the day I know the risks involved and do what I can to keep it safe as possible. As long as individuals are being responsible and not doing it for sadistic reasons then I say to each their own. This is the kind of topic that if you ask 10 people, you'll get 10 different answers lol.
