I've never waited that long...that's overkill in my opinion...I've fed the same day I've taken snakes out of their shipping boxes and handled them a few days later with no problems...they're not as fragile as people make them out to be...and by "handle" I mean take them out and hold them for a bit...not take them for a walk in the park to play frisbee...
ok, but he should at least wait until he get one meal in... yes some BP's can tolerate being handled, but some can't. The responsible thing is to wait especially if this is the OP's first BP.
