A pig is any of the animals in the genus Sus, within the Suidae family of even-toed ungulates. Pigs include the domestic pig, its ancestor the wild boar, and several other wild relatives.
Pigs are omnivores and are highly social and intelligent animals, they are actually more intelligent than most breeds of dogs!
They were domesticated around 7,000 BC. They were the first animals to ever be used domestically. A domesticated pig has approximately 15,000 taste buds, which are more than any other mammal, including humans. They are very clean animals. They go to the toilet in one particular area of their pen and never soil their living quarters.
They are native to the Eurasian and African continents.
