According to Holiday insights, this holiday was invented in 1972 by Texas art teacher Ellen Stanley.
National Pig Day recognizes and gives thanks to domesticated pigs. For some unknown reason, big, pot-bellied pigs seen in zoos, are often the symbol of the day. Pigs are clever and intelligent animals. But, most people are unaware of this high level of intelligence. They can be taught to do tricks. Some people even keep them as pets. Today is a day to give pigs the respect that they deserve.
Create something, a photo, drawing, poem, to honor pigs.
