Apparently, in Taiwan, there are 6.5 million pigs, which are a major source of river pollution. One Taiwanese farmer has potty trained his pigs to use a litter box, which apparently has conserved about 50% of the water used prior to potty training and reduced the waste going into rivers. His success has convinced the government to recommend the practice to other farmers.
Earth Times reports that Chang Chung-tou, owner of Shantung Animal Husbandry Farm in Yunlin county, started training his hogs 6 years ago after neighbors complained about the stench and pollution coming from the pig waste.
Pigs like to be in a clean environment, and can be as smart as dogs. They can be potty trained quickly, and their feces can be used for fertilizer, biogas or, after special treatment, fish and pigeon feed.

Makes you wonder sometimes why it’s so hard to train your own 3 or 4 year old to use the potty.
