Valid point - I'd think trying to supervise all those feeds would be equally tricky.
I have a few BP's that have gotten to the point that they no longer bother with constriction - once the dead rat is laid on the doorstep of their hide they'll just start gulping. Neph (afrock) won't even take anything live anymore - or constrict it for that matter - and considering her potential size that just a-ok with me lol.
