I have a 2 year old "beardie" at the nature center. He is a lot of fun! He is very gentle, except when I let him run around on the floor! Then he gets aggressive and will bite my feet, or other things in the room. Once he was on the floor and suddenly went racing across the room and attacked the feet of a full deer mount. I told him he was a silly lizard and if that deer was alive, he'd stomp on that sassy little head! Do any of you own a bearded dragon?
