Tiger may have scaled wall in zoo attack - December 28, 2007

The tiger that killed a visitor and mauled two others at the San Francisco Zoo this week may have simply scaled its exhibit's wall to attack the three, a top U.S. tiger expert said on Friday.

The 12 1/2-foot (3.8-meter) high wall built in the 1940s was short of the recommended height for walls for modern tiger enclosures, or a height of just over 16 feet (4.9 meters) urged by the Association of Zoos and Aquariums. Reuters
