A pig toilet (sometimes called a "pig sty latrine") is a simple type of dry toilet consisting of an outhouse mounted over a pig sty with a chute or hole connecting the two. The pigs consume the feces of the users of the toilet.
Pig toilets were once common in rural China, where a single Chinese ideogram (Chinese: 圂; pinyin: hùn) signifies both "pigsty" and "privy". Funerary models of pig toilets from the Han dynasty (206 BC to AD 220) prove that it was an ancient custom. These arrangements have been strongly discouraged by the Chinese authorities in recent years; although as late as 2005, they could still be found in remote northern provinces. Chinese influence may have been the origin of the use of pig toilets in Okinawa before World War II.
