I have normally fed my BP in his enclosure but he hasn't eaten in months and hasn't even shown much interest. I tried something different and put him in a small rubbermaid container and left him there for a little bit while cleaning out his cage and then offered him a warm thawed mouse and he finally took it. I was getting worried because he hadn't eaten in so long, although he didn't lose much weight. He spent the rest of the night cruising around his cage, probably looking for another mouse. I don't know if the change of scenery stimulated him to eat or not but it is worth a try.
