Reference excerpt

The ship's cat has been a common feature on many trading, exploration, and naval ships dating to ancient times. Cats have been brought on ships for many reasons, most importantly to control rodents. Vermin aboard a ship can cause damage to ropes, woodwork, and more recently, electrical wiring. In addition, rodents threaten ships' stores, devour crews' foodstuff, and can cause economic damage to ships' cargo, such as grain. Vermin are also a source of disease, which is dangerous for ships that are at sea for long periods of time. Rat fleas are carriers of plague, and rats on ships were believed to be a primary vector of the Black Death. Cats naturally attack and kill rodents and adapt to new surroundings, which makes them suitable for service on a ship. In addition, they offer companionship and a sense of home, security and camaraderie to sailors away from home. The tradition that every ship needs a mascot made cats very welcome among sailors.

History The African wildcat was probably first tamed in the Fertile Crescent during the first agricultural revolution that started about 10,000 years ago. Small cat bones excavated on Mediterranean islands indicate that cats were introduced around the beginning of the first millennium. Analysis of mitochondrial DNA of archaeological cat specimens revealed that ancient Egyptian cats started spreading in the 8th century BCE along Mediterranean trading routes and had reached a Viking port at the Baltic Sea by the 7th century CE. The study suggests that Viking sailors took cats with them on their voyages. During the Age of Discovery from the 15th through the 18th centuries, explorers and traders took them on board their ships to much of the rest of the world. The Royal Navy banned cats and other pet animals from all ships on the ocean in 1975 on hygiene grounds. However, cats are still common on many private ships. One notable example is "Toolbox" (a feral kitten born in a toolbox), the senior ship's cat, official warrant officer and "Captain's Assistant" aboard the modern Kalmar Nyckel. A celebrity in her own right, she is the subject of two books.

Cats and superstition Sometimes worshipped as deities, cats have long had a reputation as magical animals and numerous myths and superstitions sprang up among the unusually superstitious seafaring community. They were considered to be intelligent and lucky animals, and a high level of care was devoted to keeping them happy. Some sailors believed that polydactyl cats were better at catching pests, possibly connected with the suggestion that extra digits give a polydactyl cat better balance, important when at sea. In some places polydactyl cats became known as "ship's cats". Cats were believed to have miraculous powers that could protect ships from dangerous weather. Sometimes, fishermen's wives would keep black cats at home too, in the hope that they would be able to use their influence to protect their husbands at sea. It was believed to be lucky if a cat approached a sailor on deck, but unlucky if it only came halfway, and then retreated. Another popular belief was that cats could start storms through magic stored in their tails. If a ship's cat fell or was thrown overboard, it was thought that it would summon a terrible storm to sink the ship and that if the ship was able to survive, it would be cursed with nine years of bad luck. Other beliefs included that if a cat licked its fur against the grain, it meant a hail storm was coming; if it sneezed it meant rain; and if it was frisky it meant wind. Some of these beliefs are rooted in reality. Cats are able to detect slight changes in the weather, as a result of their very sensitive inner ears, which also allow them to land upright when falling. Low atmospheric pressure, a common precursor of stormy weather, often makes cats nervous and restless. Cats naturally react to barometric pressure changes, through which a keen observer can detect unusual behavior and predict an incoming storm.

Notable ship's cats The prevalence of cats on ships has led to them being reported on by a number of noted seafarers. The outbreak of the Second World War, with the spread of mass communication and the active nature of the world's navies, also led to a number of ship's cats becoming celebrities in their own right.

Aussie Aussie was the last ship's cat of the transpacific liner RMS Niagara. He was a five-year-old grey-and-white long-haired tom. His mother had been Niagara's cat before him; his father was a Persian cat in Vancouver, British Columbia. Aussie was born at Suva in Fiji. When Niagara was mined off the coast of New Zealand in 1940, Aussie was put in one of the lifeboats, but he jumped back aboard ship. A few days later, residents of Horahora, Whangarei, claimed that a cat answering Aussie's description came ashore on a piece of driftwood, and that one of them had taken him in, but the cat escaped and had not been seen since.

Blackie

Blackie was HMS Prince of Wales's ship's cat. During the Second World War, he achieved worldwide fame after Prince of Wales carried Prime Minister Winston Churchill across the Atlantic to NS Argentia, Newfoundland, in August 1941. There he secretly met with the United States President Franklin D. Roosevelt for several days in a secure anchorage resulting in the declaration of the Atlantic Charter. As Churchill prepared to step off Prince of Wales, Blackie approached. Churchill stooped to bid farewell to Blackie, and the moment was photographed and reported in the world media. In honour of the success of the visit, Blackie was renamed Churchill. Blackie survived the sinking of Prince of Wales by the Imperial Japanese Navy Air Service later that year, and was taken to Singapore with the survivors. He could not be found when Singapore was evacuated the following year and his fate is unknown.

Camouflage Camouflage was the name of the ship's cat aboard a US Coast Guard LST in the Pacific theater, WWII. He was known for chasing enemy tracer rounds across the deck.

Chibley Chibley was the ship's cat aboard the tall ship barque Picton Castle. She was rescued from an animal shelter and circumnavigated the world five times. Picton Castle's role as a training ship resulted in Chibley being introduced to a large number of visitors and becoming a celebrity in her own right. Chibley died on November 10, 2011, in Lunenburg, Nova Scotia. She had sailed over 180,000 miles at sea.

Worked examples

Example 1 — a first encounter with Ship's cat

Start with the simplest possible case. Write down what Ship's cat claims or describes in one sentence, then invent the smallest concrete situation in which that sentence is true. In science, the smallest case is usually a single object, a single equation or a single measurement. Check that every symbol or term in your sentence has a meaning in that case.

Example 2 — changing one variable

Take the situation from Example 1 and change exactly one quantity: double it, halve it, or set it to zero. Predict what should happen to Ship's cat before you calculate. Comparing your prediction with the result is the fastest way to find out whether you understand the idea or only the words.

Example 3 — an exam-style question

Typical questions about Ship's cat ask you to (a) state it precisely, (b) apply it to given data, and (c) explain a limitation. Practise writing all three answers in under five minutes; the third part is what separates a full-mark answer from an average one.

Applications of Ship's cat

In research
Ship's cat appears in science research whenever the underlying quantities have to be modelled precisely. Papers usually cite it as a starting assumption and then explore where it breaks down.
In technology and industry
Engineering practice reuses Ship's cat in design rules, simulations and safety margins. Knowing the idea lets you read a specification sheet and understand why the numbers look the way they do.
In the classroom
Ship's cat is common in secondary-school and first-year university syllabi. It links to neighbouring topics Maritime history, Ship's cats, Working cats, so understanding it makes those chapters shorter.
In everyday life
Look for Ship's cat outside the textbook — in sport, cooking, traffic, electronics or the sky above you. An example you found yourself is remembered far longer than one you were given.
