VIDEO: Mountain lion roams Westlake Village neighborhood

WESTLAKE VILLAGE, Calif. (KABC) -- Video captured what appeared to be a mountain lion on the loose in a Westlake Village neighborhood. The big cat was filmed on the Wallen family's security camera, prowling across their front yard.

"I think I watched the video over and over and over again because it was frightening," said homeowner Carolyn Wallen.

Wallen's surveillance camera caught the big cat on camera twice.

"When I saw the second video and that it had been in the yard for 45 minutes doing I don't know what, maybe it went swimming, I honestly don't know," Wallen said.

Her Husband, Bill Wallen, first noticed the mountain lion's agility over a six-foot fence.

"It leaped over that fence like it was a jumping off of a couch," Bill said.

Carolyn posted her videos alerting neighbors not because she wants anything to happen to this animal, or even because she want it relocated, but because she has grandchildren, and she also sits her children's dogs from time to time.

"I have respect for the fact that I'm living in their backyard," Carolyn said.

The Wallens have lived here for a decade and haven't noticed any mountain lions in their backyard before, but they've only had the security camera for eight months.

The California Department of Fish and Wildlife said the mountain lion that took a tour of the Wallens' property may be related to P-55, another cat spotted in the same neighborhood about a mile away one week ago. That cat attempted to enter a residence through sliding the glass doors, leaving the family inside and the dog it tried to get to shaken.

It could also be the offspring of another tagged cougar, P-23, which was recently killed and found in a roadway.

"I'm not going to do anything," Carolyn said. "I'm going to hope maybe it will move onto the mountains, maybe if it rains there will be water. I honestly don't know."
