When I have my music on my gliders make a 'sneezing' sound. ONCE in a while they make a chattering sound.

When I'm getting on my son's case (normally to go clean his room) they make a hissing.

What gives?

Is it during the day time? Because if it is more then likely its "HUMMAANN I'm sleeping!"

And they may not like your music, gliders are very vocal little guys and I wouldn't worry to much about it if there perfectly healthy. I know my guys LOVE to bark because they realize that daddy will come down the hall and maybe he'll bring a tasty treat. ;)

Sometimes it's during the day. But M-F I'm at work during the DAY hours.

Last night, well, this morning, at 1AM, my son was STILL up, refusing to go to sleep. I got on him and said 'Lay your butt down NOW; it's bed time' and they started hissing. They were awake playing when this happened. I just looked at them and said 'aren't you lucky you're allowed to be up this late!?' and laughed. They kinda cocked their heads at me and went back to playing.
