This viral video is a nice little tale of David and Goliath.
In Alaska on Sunday, Darlis Elliott found a bear prowling at the back of her home – leaving it up to her cat Nani to repel the invader.
The tiny kitty pounces with such speed the surprised bear jumps back - and falls right off the porch.
The lesson here is that housecats are, in fact, an excellent home security addition.
Earlier this week, a similar video was posted by Tom Mabe, showing his friends' cat staring down a mountain lion outside the door.
Who needs a guard dog?
