DO BPs yawn? I've seen Ben stretch his jaw or yawn or something twice. Once while he was exploring his new viv for the first time and then last night on my lap. I thought he was gonna bite me for a sec and it scared the $#*! outta me so I put him back.

My corn snake, Josephine, has never done this that I know of. Do your BPs do this too? Is this a sign of being upset or just some kind of stretch?

Thanks!
