Ok, everything looks good. Often times people come on saying that everything is in order, but they really don't know what they are doing. For once it's nice to be wrong!
It sounds like your BP is just gone on a feeding strike. unfortunately BP's are notorious for doing so with little to no good reason for it. All you can do is make sure that you continue to give your BP proper husbandry, and keep offering food once a week.
Are you offering frozen/thawed, pre-killed, or live rodents?
