Having a “ship’s cat” onboard has been a tradition on many trading, exploration, and navy ships dating to ancient times. Cats were carried on ships for many reasons, mostly to control rodents since they naturally attack and kill them. Cats also adapt well to new places, which makes them perfect for service on a ship. They also of course offer companionship and a sense of home to sailors away from home. And they were also thought to be good luck. Anyway, here is an adorable collection posted by Molly Hodgdon of navy ship cats in tiny hammocks:
