Speaking about his near-fatal tiger attack, Roy Horn, 59 (left), insisted to PEOPLE that 600-lb. Montecore "saved my life." The Las Vegas showman, who lost most use of his left side, says the animal dragged him to safety after what he thinks may have been a stroke. Horn is now at home with partner Siegfried Fischbacher, exercising regularly, reading scripts and slowly recuperating. "Thank God I'm a cat with nine lives," he says.
