I just woke up to go do some house work when I noticed my ball python out. I went up to his tank to say 'hi' when I noticed something amiss..

???


I thought he did a poop, but I looked underneath his hide and saw nothing (but few, tiny urates). I then took him out thinking he had belly rot, I checked along his tummy and nothing. Clean and white. But I noticed along the sides of his body he was feeling a little rough. Brown flakes where scattered on my fingertips. I don't see blood or any loose scales. He looks fine but what looks like poop smeared across his body that has dried out and starting to crust or something. I smelled it, but it doesn't smell like anything. I've never seen this before. Could this could be the sign of why pennyworth has been skipping a meals? I hope he isn't sick.. What do you guys think? I'll try and post more pictures on his side, but it is really hard to see.
