What animals eat pigs?
Humans eat more pigs than any other animals combined. Lions eat warthogs (in the pig family). They dont have many natural predators in North America. Wolves used to keep the populations of wild boars down, but we have depleted the wolf populations. Usually any carnivore/omnivore large enough to take down a pig, will eat them. Pigs are not filthy animals. Being dirty would have nothing to do with them having few predators. They are very clean, and are more intelligent than dogs. They can recognize and understand up to 100 words. The only reason they have the stereotype of being dirty, is the way we treat them on farms. They are forced to live in filthy conditions. They have no sweat glands so they roll in mud to cool themselves. And their physiology is very similar to humans.
