Throughout history, horses, dogs, and pigeons have all been used to help deliver mail. In 1876, the small city of Liege, Belgium thought, "why not try out cats?". A small group called the Belgian Society for the Elevation of the Domestic Cat trained 37 cats to find their way back home after being left in far-away fields. The cats took over 24 hours to do so, and the experiment was deemed an utter failure. Since then, no country has tried to use cats as messengers, especially after the rise of Email and cell phones.
