The video cameras, which are installed at the front porch of the house of a resident of San Francisco, in the US State of California, have recorded a mountain lion dragging a dead deer away.

This video was posted on YouTube on Thursday, and it was viewed more than 16 thousand times in one day, reported Lenta.ru, a Moscow-based online newspaper.

“A ruthless mountain lion was caught on camera attacking a deer on Peter Rauenbuehler’s front porch in San Francisco on December 14,” reads the commentary attached to this video. “The deer had wandered onto the porch to eat some roses, but was slammed into a set of metal railings by its attacker. The mountain lion then brought its prey’s life to a quick end by breaking its neck and dragging the carcass away.”
