A very special kind of prowler sat in a Paraguayan jail cell Sunday: a small tiger cub found on a rooftop. People in Itaugua Guazu, about 40 kilometers (25 miles) east of Asuncion, called police about the meandering feline Friday. One witness told a radio station it is not much bigger than an adult house cat. The cub remained in a jail cell for safety purposes while authorities try to figure out what to do with it. No one knows where it came from or how it got on the roof.
