Well I bought two BP's this past weekend at a reptile show here in San Antonio and have no previous experience with snakes only lizards and more furry creatures. After talking to the guy I purchased the snakes from he told me that the smaller pastel boy was eating adult mice, and the larger normal girl was eating rat pups. The boy is about 3.5" around and the girl is 4.75". He also told me that in 2 feedings I should be able to switch the pastel boy to rat pups as well. Somehow I think thats a bit large for how young of a snake he is(he's from a fall clutch) especially seeing as the girl is over a year old and is just eating rat pups. Would an adult mouse for the pastel boy and 2 adult mice for the girl be ok?
