Would I take him? If the price was right as a Vet call is needed, and if I was ready for a 6 month quarantine. Either the guy is lying about feeding him every week for 4 months (16 mice) or the snake has parasites/worms ect. I just got a under weight Hatchling (2.5 months old ) & it went from 57g to 130g within 4 weeks. So with that understanding and a reduced price, yeah id go for it..... Otherwise you can get a Healthy Pie from a reputable breeder for the same price or possibly less than you might have to put into this BP after who knows how many vet visits...
