I was setting out some food for my Sulcata hatchling this evening and he was eating like always and I look over at him and all of a sudden he bit his own arm! He immediately went into his shell, as much as he could, with his mouth wide open with his arm inside! I was really freaking out! I continuously tried to get his arm out of his mouth for what seemed like forever! When these attempts failed I figured I'll just let him try and handle this himself. Well, all he did was go in circles round and round not lettting go of his arm! Finally he did let go and now he seems to be terrified! He isn't bleeding and he's walking around fine now using the bitten arm. But, my gosh, this was just very upsetting!!
