Coughing: Choking - possibly?

[Yoshi&Sebastian]

About an hour ago my girlfriend and I were rearranging the pig cage (we've built a 2x5 C&C with fleece and towels since my intro topic) and noticed Yoshi was doing something that could only be described as a silent dry heaving. He repeatedly (and fairly quickly) curled his head and butt in but remained standing just fine. A second or two after I noticed it, he coughed once, shook his fur out, then started playing around the cage as normal.

I noticed a few minutes later he'd moved to the corner where I had one of the pellet bowls in before I rearranged the cage and he had pulled the fleece out from the way I'd folded it and was gnawing on it. I picked him up out of the way, folded it back around the towels and he has been ignoring it since.

Was he actually choking? Could it have been him gnawing around where the pellets used to be?

Also- I brought him to an exotics vet a couple of weeks ago for a checkup and he was fine.

I just re-read this and it kind of sounds like I'm describing him eating his own poo, but it's different. When he eats his poo his back feet stay planted on the ground and it's obvious, this time they were being scooted forward towards a central point along with his front feet scooting backwards towards the same point. His head tucked under himself. He was partially covered by his hidey-house so I couldn't see if there was something in his mouth, and nothing was left behind that he would be coughing up. I didn't pick him up immediately for fear of exacerbating the problem.

Sometimes pigs get things caught in their throat and will choke or cough to dislodge it. Many do this when they attempt to eat too fast. It's a normal thing.

Oh alright - thank you. New pig owner here, kind of jumpy.
