Shedding or. . . ?

[Homebody]

His starting weight with me was 206g, then 213.5 two days after eating, tonight it was 173g. That might not be very accurate because he was really trying to get off the scale.

I think it's safe to say, your bp didn't lose 20% of his body mass in two weeks. I don't know if that's even possible. But please don't re-weigh him. I agree with Boger and Ziggy. Weighing your snake too often is counterproductive. I take my snakes weight every three months.
