The zoo has hired well-known crisis management spokesman Sam Singer to handle public relations after the mauling. Singer criticized many of the arguments offered by Geragos for the suit.
"On the face of it, his claims appear to be false and most are based on misinformation," Singer said. "If you take a look at the actual facts, you'll have a hard time proving them [Geragos's claims]."
The zoo, which reopens Thursday since closing after the attacks, could also face heavy fines from regulators and even be stripped of its exhibitor license. The U.S. Department of Agriculture sent inspectors and could impose fines on the zoo.
When the zoo reopens, the tigers and other large cats will not be on exhibit in the outdoor enclosures, a zoo spokesman said. The tigers will be moved to another location within the facility where they will have a safe space to exercise.
The zoo could also face criminal charges, based upon the results of a police investigation.
"They're going to try to determine how the animal got out and whether that violated our regulations," USDA spokesman Jim Rogers told The Associated Press. "A facility must have a sufficient barrier between the viewing public and the animals."
Zoo officials or spokespeople could not be reached for comment on New Year's Day.
Monday, a spokesman announced that the zoo was working with the city's Recreation & Park Department to design a new security system for the tiger and lion grottos, which should be ready in 30 days. The zoo has also invited the Association of Zoos and Aquariums to tour and inspect its facilities, according to the spokesman.
