I had Bing outside for a run and took all the precautions. I had a dirt blocker for planters thing in a big circle so couldn't get out, I put a chair over it so a hawk couldn't swoop down a get him and I had the dogs locked in. And after about a half an hour I looked outside and saw a roadrunner standing at the edge of the circle looking at Bing so I started screaming and running at it and scared it away. I haven't seen one in years and it was a day after I think it was sharkstar told me that they will go after tortoises. I was just in time if I looked out probably a minute later I would of thought he escaped.
