♥ Pigs are extraordinarily intelligent. They are curious and insightful animals who are widely accepted as being smarter than young children of at least 3 years of age, dogs, and even some primates.

♥ Pigs are extremely social animals. They form close bonds with other individuals and love close contact and lying down together.

♥ Pigs are very clean, keeping their toilet area far away from where they lie down and eat. Even newborn piglets will leave the nest to go to the toilet within hours of birth.
