Neighbors in the Pinery area of Parker have started an email chain to warn each other about a mountain lion roaming the neighborhood."This is a huge cat," one of the neighbors wrote in an email chain."It's killed at least two deer and a fox in the last 6 or 7 days," said another neighbor.Neighbor Ed Silver has three motion-detection cameras in his back yard to capture pictures of animals. He's seen raccoons and foxes."In 11 years, I've never seen a big cat," Silver told 7NEWS. "It was four feet from our deck."The mountain lion was first spotted in the area in May. There have been several more reports of sightings in the last few days."Just to be on the safe side, you may want to have your kids come in before it gets to be dusk," one neighbor warned in the email chain.The Division of Wildlife said it is aware a mountain lion is in that area.There are a lot of deer in that area and that is what mountain lions eat, said Division of Wildlife spokeswoman Jennifer Churchill.If you see a mountain lion, call the DOW, Churchill said. That will help them track the mountain lion and determine if this is a problem mountain lion or an animal that is just passing through the neighborhood.
