Who wants to wait a couple hours? I just put the rodents in a zip lock baggie, fill a bucket with hot tap water, put a weight on the bag to hold it under water, then in 15 minutes, change the water with hot tap again and then wait 5 min. and feed. The feeding behavior you refer to is the nature of BP's, if you want a snake that feeds "on demand" get a garter snake.
