SAN MATEO -- Another mountain lion was spotted in an unincorporated area of San Mateo on Friday morning, police said.
The animal was spotted about 7:30 a.m. in the 2000 block of Lexington Avenue in the San Mateo Highlands, between Lexington Avenue and Interstate 280, according to San Mateo police.
The sighting marks the third time this month that police have received reports of a mountain lion in or near the city.
The first big-cat sighting occurred about 1 a.m. on July 1 near a backyard on Fernwood Street. Police found a deer carcass in the area and determined that the animal was probably killed by the mountain lion.
The second sighting was in an unincorporated area on Queens Lane about 5:30 p.m. on July 5.
It's still unclear if the sightings are of the same mountain lion or different animals.
Police have said that because of the city's proximity to open space areas populated by wildlife, interactions with mountain lions and other nondomesticated animals are a regularly occurring safety concern.
San Mateo police ask that if anyone sees a mountain lion or receives a community alert about one in the area, do not approach it, especially if it is feeding or with offspring. Most mountain lions will try to avoid confrontation with humans.
Police also asked residents to avoid hiking or jogging when mountain lions are most active -- dawn, dusk and at night. Keep a close watch on small children, and supervise all children and pets in your yards, police said.
If anyone encounters a mountain lion, do not run; instead, face the animal, make noise and try to look bigger by waving your arms. Throw rocks or other objects and pick up small children or pets that could be an intended target.
Also, police said not to leave pet food or any other food outside at night that would attract wild animals.
