I have a three month old male BP that strikes at everything on feeding day. He is ready even before I open his enclosure. I was feeding him live small adult mice or rat pups. I have been able to sucessfully convert him over to f/t prey. He can be a bit hissy at times too, but he has an awesome feeding response as most babies do. I can handle a little bit of an attitude problem. It's a small price to pay for having such an excellent feeder.
