Ok, so for future reference, any snake being handled can poop at any time, which will consist of watery white or yellow stuff and less watery brown stuff, which will all smell strongly of snake poop. _If_ you find a fresh poo in the viv, you are most likely safe. I have 12 snakes and have been actually pooped on twice, maybe, and had a snake poop on the carpet a couple times. It's not that common.
