An underage mountain lion has been caught after trying to slip into a casino in downtown Reno, Nev., ahead of the breakfast rush. Nevada Department of Wildlife spokesman Chris Healy says the young male cat's behavior was "almost the equivalent of being a stupid teenager." Healy says coming-of-age cougars often end up where they shouldn't after being chased out of a territory by adults. Guests at Harrah's reported seeing the 100-pound cat trying to walk into the casino. When the animal couldn't negotiate the revolving door, it hid under an outdoor stage in a nearby plaza. State wildlife officials tranquilized the roughly 2-year-old cat and plan to release it into the wild after tagging it for participation in a University of Nevada, Reno study. Officials planned to tag the animal and check its health before releasing it back into the wild. No injuries were reported.
