hahaha well, he was on rat pups but I am having a hard time getting them here so I tried him with adult mice(smaller mice from an order). He has never missed a feeding(knock on wood), even when shedding he'll eat.. Just an all around awesome snake to have. Always sheds perfectly as well, never hissed, or tried to bite me.. I received him on October.27/08. I believe he was born in August. The first pics are the day I got him.
