Good call, his next meal will be a weaned rat!

General retic question for anyone- since I've had him, his tongue flicks are short, as in just sticking out the forked portion of his tongue. They aren't quick or fast, he just doesn't stick his tongue out all the way. Is this an individual behavior that's somewhat normal, or is it a stress indicator? When he's doing it, there aren't any other signs of anxiety or stress.
