A couple of years ago, he dug a hole that went under our neighbor's property. He wasn't trying to escape. When he digs, the tunnel just keeps going deeper. It never comes up. He just keeps instinctively increasing the size of his burrow. My neighbor got upset and built a wall that was sunk several feet into the ground to keep Charlie on our side of the fence. Now he has a hole that goes under our patio. During the winter, he might stay under for several weeks. If it gets rainy or too cold, he has a spot on the patio with a heat lamp. During the warmer months, he is out most of the day. If I go out into the yard, he comes over to see me. He is shy around strangers. He recognizes me. He isn't really affectionate but he lets me pat his head and he will eat out of my hand. When the plums fall off the tree, he gets plum juice all over his face and it looks like he is wearing lipstick.
We call him a bulldozer because he never thinks about going around objects. Sometimes he will go under the patio furniture and end up carrying it on his back.
When he was a baby, I took him to show and tell for my daughter's class. I didn't realize then that reptiles could get nervous. It was traumatic for him.
