My male sandboa seems to yawn more than necessary (cue the avatar), sometimes he just opens his mouth a little bit, and he seems almost to have an adam's apple. Sometimes it sounds like there's a little bubble popping in his throat. Kinda has me worried. He hasn't eaten the last two feeding either, though I think he's just not liking f/t. He's always eaten live before. He fed for me twice since I've had him, both live.

He's active though, and flicks his tongue like normal. Any ideas?
