Cute Piglets and their Mama

PIG
Despite their reputation, pigs are not dirty animals. They’re actually quite clean. The pig’s reputation as a filthy animal comes from its habit of rolling in mud to cool off. Pigs that live in cool, covered environments stay very clean.

Piglets weigh about 2.5 pounds (1.1 kilograms) at birth and usually double their weight in one week. Fully grown, pigs can grow to between 300 and 700 pounds (140 and 300 kilograms), and sometimes much more. Pigs have poor eyesight, but a great sense of smell. The pig’s nostrils are on its leathery snout, which is very sensitive to the touch. The pig uses the snout to search, or root, for food.

Pigs are among the smartest of all domesticated animals and are even smarter than dogs.
