Residents are advised not to hike or jog when mountain lions are most active -- at dawn, dusk and night, emergency officials said.
Residents are also reminded to keep an eye on small children and not to run if a mountain lion is spotted, but rather to face the animal, make noise and try to appear bigger by waving arms and throwing objects.
County officials warn hikers not approach a mountain lion, especially if the animal is feeding or with offspring.
