TARZANA, LOS ANGELES (KABC) -- A Tarzana neighborhood was on high alert after the latest sighting of a mountain lion in a residential neighborhood.The mountain lion was captured on Jeff Shulman's Nest surveillance camera in the 4600 block of Mirador Place.The lion was roaming on the sidewalk Sunday just before 5 a.m."I was blown away, I was absolutely blown away. I saw this big head and this big tail," said Shulman. "I started to notify neighbors and let them know that there was a mountain lion cruising the street....we have no idea where it is and to be aware," he said.Shulman's neighbors, Jim and Suzanne, have seen plenty of coyotes in the neighborhood, but the mountain lion changes everything for them when it comes to protecting their dogs."We're used to to coyotes. We see coyotes all the time. We have cameras on the block. We talk to neighbors. It's a common thing to see coyotes in the neighborhood. It's a big deal, but not a big deal. A mountain lion was shocking. We're more vigilant now than before," Jim said."We can't leave (our dogs) out here unattended. No water in the front, no food. Nothing. It's very scary," Suzanne said.Shulman and some of his neighbors contacted the California Department of Fish and Wildlife. They said they were told nothing can be done unless the big cat attacks a person."They're beautiful animals but there should be some kind of program where they're monitored and tracked and alerts go out warning, "Hey, there's a mountain lion in your front yard," Shulman said.This was the latest sighting of a mountain lion that felt too close for comfort for some residents. Simi Valley neighborhood was on edge Friday morning when a mountain lion was seen prowling the streets less than 48 hours after two dogs were attacked, one fatally, in the same area.
