I'm very sorry to hear about Chameleo; glad you have Chamelia Earhart so you're not completely chamless. I have had to prevent Thaxter from heading into the street on more than one occasion, and always escort him when he's walking down the sidewalk, as he's utterly oblivious to joggers, bikers, cars, etc. - they do seem to favor streets and sidewalks, presumably because it's easier going for them than grass.
