Maybe a cough or like Haley says, a "hacking" sound? Did he do it again? What was he doing when he made the noise? Did he look like he wanted you to back off or anything?

I recently had myself convinced that my pigs were coughing or sneezing and that they all needed to get to the vet - STAT - until I sat and watched them and learned that the horrible death noise they had been making was actually just the sound of their little paws scraping on the coroplast occasionally.
