SAN FRANCISCO - Renovations to the big cat exhibit at the San Francisco Zoo are complete following a fatal attack by an escaped tiger.

The zoo's lions and tigers are getting their first look Monday at the renovated pen. Once the animals acclimate to their surroundings, officials will decide when visitors can see the cats.

The animals have been kept indoors away from public view since a Siberian tiger killed a teenager and mauled his two friends on Christmas Day.

The renovations include raised walls, new glass barriers and electrified wires to keep the animals from trying to escape.

Before the improvements, the exhibit's walls were about 1.2 meters lower than national guidelines suggested. The renovations raise the walls to the recommended height of five meters.
