They are often pink, but small ones kept as pets are often other colors. They often roll in mud to protect themselves from sunlight. Many people think that pigs are dirty and smell. In fact, they roll around in the mud to keep parasitic animals (such as little bugs and ticks) away from their skin. This also helps to keep their skin moist and lower their body temperature on hot days. They are omnivores, which means they eat anything that comes in their way. Because their eyes are on the sides of their heads, pigs cannot look up to the sky.
They need lots of water. Over half their body weight is made up of water. Pigs should be given all the feed they will eat, which is usually 4 to 5 pounds a day for adult pigs. Corn is a good food for pigs, but they should also have protein supplements as well.
They are often found on farms throughout the world and can be popular pets. A new breed of micro pigs has become very popular but often piglets are misold as micro pigs and then grow to be too big. In places pigs are mass farmed to produce the best animal for meat. These meat farms are often overcrowded with pigs and conditions are really bad.
