Strange cough?

[piedpython]

Does he appear to have had a bowel movement recently? If a snake has a particularly large poo, they will open their mouth while passing it, they strain to excrete just like any other animal. I have a suspicion that what you were hearing was a fart, not a cough.

If it was in fact a cough, I'd definitely schedule a vet appointment.

I think you solved it! I took a closer look and there is fresh feces right where he was doing that noise. Strange thing is some of it is solid and some is wet almost like diarrhea. I've had him for two months now and he has passed solid urates but has not had a bowel movement. Maybe he is constipated and straining?
