I do not have a scale to weigh, I will try to get one tomorrow. His sale page said live rat. My wife fed a mouse pup, very small. Apparently he killed it without apparent issue and ate. It was the next day when she checked on the snake she noticed that he was very defensive and striking, but she did not investigate any further. She texted the breeder and told him he was very defensive, he told her that it was probably going into shed, which makes sense. It was not until I got the snake myself that the problem was identified. He has not eaten since nor shows any interest. I put a rat pinky in with him and he acts very scared of it. I do not want to have to force feed him either.
