SAN MATEO, Calif. (KGO) -- San Mateo residents are being asked to stay on high alert after several mountain lion sightings this weekend, two that were caught on surveillance video in a backyard.

Sue Galloway lives next door to the homeowners that captured the video.
She says the creek in their backyards attract deer and other wildlife. When she heard about the mountain lion, she wasn't surprised.
"No, but I was surprised to see how big he was. I'm not going to be in my backyard for a while," Galloway said.
Garrett Smallwood lives in the area and said there was a mountain lion sighting at a park two weeks ago.
"I was literally stopped by a park ranger who was like don't go in there, there's been a mountain lion sighting you want to turn around and go around the other way," Smallwood said.
He said it's good to be aware since there is a lot of wildlife in the area.
"We have a dog, we have a young kid and it's like frightening to have a huge mountain lion running around your yard," Smallwood said.
There have been multiple encounters in neighboring Pacifica including one earlier in the week at San Pedro Valley Park.
Police remind residents to avoid hiking or jogging through wooded areas when mountain lions are most active, like at dawn, dusk and in the evening.
