First off I would not worry, second when a bp is eating consistently and then goes off food it IS NOT a hunger strike, it's not like the animal says ok I've decided to starve myself. Bp's have a tendency to go off food from time to time I have had bp's go off food for 11 months or more and then one day they decide they want to start eating again. So I would not worry, and offer prey once every 2 weeks until the prey is accepted and then continue with your normal feeding schedule
