I'm not one for strict feeding schedules either (as Malum Argenteum explained in above post), but we both have lots of snake experience under our belts & I know that when you're fairly new at snake-keeping, it's understandable that you seek "guidelines" to make sure you're doing it "right". Anyway, that's why I often remind everyone that nature sure doesn't deliver meals on schedule either, nor are they all identical (weight or even species). Some flexibility is just fine- it's actually more realistic. And many of us have our own methods that work for us & our animals.
(That hognose bite sure must have been epically messy!)
