A mountain lion with a cub was reportedly seen in Portola Valley Wednesday night, San Mateo County emergency officials said.
The cats were spotted near the driveway of a property under construction in the 5900 block of Alpine Road at about 8 p.m., officials said.
Residents are advised to never approach a mountain lion or go near a mountain lion cub. Most mountain lions avoid confrontation with humans. Anyone who encounters a mountain lion should face the animal, make noise, and try to appear larger by waving arms and throwing rocks, emergency officials said.
