Why was my hedgehog squeaking?

Last night I was up later than usual, so I was awake when my male hedgehog came out to play. He was running on his wheel when all of the sudden he stopped, got off, and started squeaking. It wasn't a long squeal, just a few short bursts of squeaks. They didn't sound like he was in distress, (though to be fair, I've never heard him scream, so I don't know what he sounds like when he's upset.) but when I tried to look online, some people suggested it might be seizures-others said he was expressing contentment. Should I take him to the vet to get things checked out?
