Mountain lion walks by front doorstep in suburbs

The increasing adoption of doorbell surveillance cameras, particularly in the US, has turned up some real surprises.

But one California family were not expecting to see this on their doorstep!

Shockingly, a mountain lion is seen wandering into their suburban garden and loitering by their front door.

According to a local news site, the homeowner had to call in animal control to remove the beast and neighbours were told to stay in their houses while the big cat was safely taken down with a tranquilizer dart.
