The Nagasaki Bio Park zoo in Japan has an ingenious and incredibly cut way of moving large amounts of guinea pigs between enclosures.

When the zoo staff need to move the guinea pigs from one play enclosure to the next, they extend what is possibly the most adorable suspension bridge in the world across the gap between them.

The guinea pigs, which seem to know exactly what to do, file across in an orderly fashion.

So civil!
