Haha, you'd be surprised how much we get to talk about poo here!

At this stage in the game there is probably little to worry about, he may just be building up for a monster poo after his next shed. I think constipation is not too far behind the skipped meal ordeal when it comes to problems snake keepers over worry about. Now if he doesnt poo for say, another few weeks then I would definitely head to a vets office, but right now.... I think your fine.
