WATCH: Man Shoots Mountain Lion That is Stalking Him

A hunter becomes the hunted as a mountain lion is stalking him. In the video below you'll see him try anything he can think of to make the beast go away. “Stay back, stay back!” the hunter warns the cat. He did not really want to shoot in. But in the end, he had to.

Everyone is carrying cameras these days. That's how the moment the hunter had to pull the trigger on the animal that was hunting him was captured.

The cat looks young. It was hoping that it was well hidden in the brush and did not understand that the human could see him and was able to deal with him.

The moment that is capture is hard to watch. The cat steps out of the brush and considers his next move. Then, he makes his move. The hunter shoots. The actual shooting is a bur. The hunter was paying more attention to the cat and his gun than his camera. The animal falls and lays there twitching for a while.

The hunter is upset by what he just had to do. After taking a while to calm down he walks over to inspect what he just killed, even opening its mouth to inspect the cat's big teeth.

I found some advice on what you should do if you ever find yourself in this situation.

Avoiding Mountain Lion Attacks, according to the national park service.

Do not run from a lion. Running may stimulate a mountain lion’s instinct to chase. Instead, stand and face the animal.

Make eye contact. If you have small children with you, pick them up if possible so that they don’t panic and run.

Although it may be awkward, pick them up without bending over or turning away from the mountain lion.

Do not crouch down or bend over. A human standing up is just not the right shape for a lion’s prey.

Conversely, a person squatting or bending over resembles a four-legged prey animal. In mountain lion country, avoid squatting, crouching, or bending over, even when picking up children.

Do all you can to appear larger. Raise your arms. Open your jacket if you are wearing one. Again, pick up small children.

Throw stones, branches, or whatever you can reach without crouching or turning your back. Wave your arms slowly and speak firmly in a loud voice.

What you are trying to do is give the big cat the idea that you are not lunch, but you might make him lunch, or at least be a problem to him.
