Workers twice reported spotting what they believed was a 3 to 4-foot mountain lion with a long tail near 218 Family Farm Road in the Portola Valley area, according to the San Mateo County Sheriff's Office.
The first sighting was reported at 10:30 a.m. Thursday, according to the sheriff's office. A second sighting occurred at around the same time on Saturday, during which the mountain lion was reportedly stalking a jackrabbit.
Officials issued a warning Monday that the suspected mountain lion may be traveling around Sausal Creek and to use caution when in the area.
Anyone who encounters a mountain lion should not run from the animal, and should not crouch or bend down, but rather try to appear larger, and make noise.
Mountain lions are timid and typically do not seek out humans. However, if a mountain lion attacks, wildlife officials advise fighting back.
