Do your sulcatas have free roam of the yard like mine? My big sulcata, "Ozzy" is the complete opposite if we have company. He basically demands attention if we have someone over. He's definitely not shy when it comes to people paying attention to him. The females are another thing entirely. If we have two or three people over, they are the first to hide under the bushes. Its hard to say if they tell people apart by smell or sight.
