That is a very typical looking poop....guaranteed. Seems after seeing and cleaning many countless thousands of these over the past four decades, I should be able to ID these pretty darn well by now..LMAO!!
Like the others mentioned, a regurge is absolutely
GROTESQUE smelling!! from it actually putrifying(rotting), whereas a poop simply stinks a bit as would be expected.
It's definitely good it wasn't a regurge, because that can cause VERY serious and rapid "domino effect" problems if not addressed properly ASAP!
BTW, if a snake will accept a meal while in "blue" just prior to a shed, then it is perfectly fine. And if an individual doesn't feed while in it's shed cycle, then that's fine too.
