I fed my BP a small rat which actually was a medium rat(I wasn't paying attention) and after about 30 mins of wrestling, she got it down and went into a food coma for almost 2 weeks. I usually feed her once a week but the super size meal tied her over longer. After a couple weeks, she was out looking for another rat. Just give her an extra week to work up a good appetite and she should be fine. When mine was a baby, she was ALWAYS hungry. Now she is 1064g and about 7 months or so old and she isn't nearly as hungry as when she was a baby. Just wait until she comes out and looks for food, then buy her a rat. That's kind of what I do now. I used to feed 3-4 days as a baby and weekly like clockwork once she hit 400g ish but now I just kind of feed her when I see her out, usually right around the 1-1.5 week mark.
