I was in the same boat a few months ago. My first snake ever... I never really saw any poop that was bigger than maybe a pea. Then about a month later, she went into shed... the day I found her shed, she pooped... a LOT.

Like you, I was worried before I saw this. The consensus is exactly what Deborah said... when they are young, there isn't much waste from their meals as they are absorbing everything they can. Some folks said their BP's were quite "regular" and passing stool every week, while others said theirs really only went around shed time. I don't think you need to worry.
