2003: During a show at The Mirage in Las Vegas, Roy Horn of Siegfried & Roy is bitten on the neck by a 7-year-old male tiger named Montecore. Horn suffered severe blood loss and would remain in critical condition for several weeks thereafter. The attack would prompt The Mirage to close the show and Montecore was put into quarantine for 10 days in order to ensure he was not rabid, and was then returned to his habitat at The Mirage. In February 2009, the Siegfried & Roy staged a final appearance with Montecore during a benefit performance. The pair officially retired from show business in April 2010.
