Feb. 15 (UPI) -- A zoo in Thailand is encouraging humans to clean up after themselves by training an otter to clean up after some particularly sloppy pigs.
A video of an animal performance at Chiang Mai Zoo in Thailand shows a group of pigs living up to their name by knocking over a wastebasket and spreading around the trash.
An otter then arrives and methodically puts the trash back into the bin.
The filmer said the message of the performance was: "Don't litter or someone else will have to clean it up."
