Watch these smart pigs display extraordinary intelligence while dealing with the most horrific situations. The cleverness of the pigs will blow your mind!

Scientists state that pigs are the 4th most intelligent animals in the world, right after chimpanzees, dolphins, and elephants. Their intelligence is not yet fully understood, but we're already aware of their high ability to solve complex problems, socialize, help each other, remember things, and just think.

On meat farms, however, these highly-intelligent animals are subjected to a life of extreme boredom and misery. After they get mutilated shortly after birth without any painkillers, they are forced to spend the rest of their lives confined, in tiny spaces with nothing to do. No ground to dig in, no pond to splash in, no vegetation, no sunshine, no hikes, no running, and climbing. Just nothing.

Needless to say, such living conditions do drive the intelligent pigs insane. Common behaviors include pigs repetitively chewing the cage bars despite having no outcome. And of course, the heartbreaking act of pigs chewing off the tails of their siblings, as a result of extreme boredom, stress, and despair.
