The San Francisco Zoo reopened its big cat grottos for public viewing almost two months after a man was fatally mauled by a Siberian tiger that escaped from its enclosure on Christmas day. Renovations to the enclosures included an extension of the concrete moat to 16 feet, 4 inches from the bottom, installation of glazing and fencing barrier, and installation of a hot wire electric fence.
