Why do aircraft carriers keep cats? It's not just for catching mice, but for an even more important purpose.
Historically, wooden sailing ships were the primary means of sea trade, carrying goods and dreams across uncharted waters.
However, these ships also brought along an unwelcome guest: rats.
Rats breed rapidly and quickly became a significant problem for sailors.
They scavenged for food on the ship, wasting supplies, gnawing on the wooden structure of the ship, and potentially damaging critical parts, posing a serious threat to the voyage.
More alarmingly, rats carried various diseases, such as the plague and typhus, which were especially dangerous for sailors living in the confined spaces of a ship.
Early maritime technology was limited, and people were helpless against these pests.
Eventually, they discovered that house cats were naturally skilled at catching rats, so cats were brought on board to control the rat population.
The cats' agility and hunting instincts made them indispensable crew members.
They patrolled the ship at night and hunted during the day, effectively reducing food loss and disease transmission.
Although cats were highly effective at catching rats, a few cats were not enough to manage the problem entirely on the vast ocean.
If the number of cats was insufficient, rats could proliferate again.
With the advancement of technology, people sought new methods to combat rats.
For instance, in the 1980s, the U.S. Marine Corps experimented with infrared detection devices to locate and capture rats, hoping to reduce their reliance on cats.
However, since rats could adapt to environmental changes and evade infrared detection, this method was not widely adopted.
House cats remained the most effective rat control solution.
Meanwhile, the Chinese navy adopted a different strategy.
During each maintenance period, they meticulously inspected and sealed any potential entry points for rats, preventing the problem from occurring in the first place.
This prevention-first approach demonstrated the Chinese navy's thorough and comprehensive mindset.
Moreover, the role of ship cats in the military extended beyond catching rats.
During long periods at sea, cats provided psychological comfort and emotional support to the sailors.
Their resilience and cheerful disposition boosted morale and fostered camaraderie and fighting spirit among the crew.
In Western maritime culture, cats were often seen as symbols of good luck and safety, considered protectors of the voyage.
Many countries' warships have maintained the tradition of keeping cats, hoping they would bring good fortune to their journeys.
Even in modern times, despite technological advancements, the unique status and important role of ship cats have not been overlooked.
They are not only "warriors" against rats but also emotional "companions" for the sailors.
This enduring bond between humans and cats, passed down through generations, bears witness to the glorious history of maritime civilization.
In summary, paying close attention to details and valuing the special role of ship cats in the military can further enrich and continue the unique essence of maritime civilization.
