i see mine yawn if i have them out a bit before the sun comes up
maybe they do it because they are getting tired
i know what ya mean the first time mine yawned and i was holding him i was expecting a tag
however my female jungle looks like she is yawining but you have to be carefull with her as i think she is trying to measure up my fingers as she as got me a few times by a yawn then latching on
