LOL All my big fat happy Ball Pythons must not have read jamies care guide to Ball python husbandry
all i can say is after 8 years of keeping a Large collection is that all my BPs thrive and grow nicely with eating those large meals,even if went by the girth rule i dont have Anything over 6 months old that would eat anything smaller than medium rats and as far as Bps having slow metabolism and fasting to "catch up" as you put it,is completely off base...My animals eat every 7-10 days with VERY few exceptions (either in shed or lower temps for breeding)
And even on this "ridiculous" feeding schedule they thrive and produce very nicely and none are obese..just good hardy well feeding animals
