Pacman Yawning???? I think...

[unkempt1]

Do they also do this if they are hungry? Every time it seems its been a few days since I have fed my guy, he will come out of his hole and start opening his mouth randomly. I thought that maybe, if he lived in the wild, this would work for catching flies and things.

The only other time mine does it is right after he swallows some prey. He'll shut his eyes, then open and shut his mouth quickly as he opens his eyes back up.

Yes its the same yawning motion. This is how they swallow their prey and shed skin.
