When you offered his food did he show interest in his hide? Tongue flicks or nose poking? Could you explain your method exactly how you presented the mouse/rat to him? how you held it up and if you did any motions? For example, dangling the feeder by the tail isn't recommended or some bp's are turned off by that. Presenting the feeder's nose facing towards your bp tends to be more effective of has a stronger reaction.
Tongue flicks and looking at it then he’d instantly turned away. I warmed it up in a bag with hot water then blow dried it to warm it up even more. I did motions and I held it alittle close to his face.
