The bobcat ("Lynx rufus") is a fierce cat that lives in forests, swamps, mountains, prairie, and deserts in much of North America. Bobcats are generally nocturnal (most active at night), but are most active at dawn and dusk. They spend the day in their den (a cave, hollow log or rock crevice). They are very good climbers and swimmers. Bobcats are eaten by cougars, coyotes, wolves, and bears. Bobcats usually live from 10 to 14 years. Bobcats and lynxes are closely related.
