Tried feeding again tonight, thawing the rat pup in the same bag as mouse and rubbing the two together....
As soon as a I turned on the hairdryer, my BP started poking his head out of his hide. I presented the pup and he struck while inside his hide but missed. His head would follow the pup wherever I moved it. I reheated the pup about 5-6 times and each time he seemed interested but never struck. I decided to let the pup in the cage and come back the next morning to see if it's gone.
