Okay, show's over for today, and I can give you what feedback I remember and will email everyone the audio files when I get them! aTailOf2Kitties - they said if this is a brand new behavior it might be worth a vet trip, but as it is only happening when he's asleep it could just be a happy, deeply asleep kitty.

They mentioned hearing - do you try to wake him vocally, and maybe he doesn't hear you? They all agreed that, as it only happens when he's asleep they doubt it is any kind of seizure, they mentioned a few other things, I'll send you the audio file when I get it!
