Top 10 Most Intelligent Animals

6. Pig


Pigs are extremely clean (going against their filthy reputation) and are as trainable as dogs. They make wonderful pets if you have the space for one.

In the 90s an experiment showed just how intelligent pigs were. They were trained to use a cursor with their snouts and made to distinguish between scribbles they’d seen before and ones new to them. They picked it up as quickly as chimpanzees.
