Cats and Ships - Saving Lives!

Cats were commonly kept on ships during historical times, particularly during the Age of Exploration and the era of long-distance sea voyages. They served a valuable purpose on board by helping control and prevent the spread of diseases. Here's how cats contributed to this important role:

1. Controlling rodent populations: One of the main reasons cats were brought on ships was to control the population of rats and mice that infested the vessels. Rats, in particular, were notorious carriers of disease, and their presence on ships posed a significant threat to the crew's health. Rats could carry diseases such as bubonic plague (the Black Death), hantavirus, leptospirosis, and others, which could cause deadly outbreaks.
2. Disease prevention: By keeping the rodent populations in check, cats helped reduce the chances of diseases spreading among the crew. With fewer rats around, there was a lower likelihood of diseases being transmitted through contaminated food and water or by direct contact with the rodents.
3. Boosting crew morale: Long sea voyages could be physically and mentally challenging for sailors. Having cats on board provided companionship and entertainment, contributing to the crew's overall well-being and morale. A happier crew was more likely to remain in good health during the journey.
4. Spiritual beliefs: Cats were sometimes considered to possess supernatural qualities and were believed to ward off evil spirits and bad luck. Sailors often viewed cats as lucky charms or symbols of protection, which may have provided a psychological boost and helped alleviate anxiety during dangerous voyages.

It's essential to note that while cats did play a role in helping control rodents and potentially reducing the spread of diseases, their presence alone would not have been enough to entirely prevent disease outbreaks on ships. Hygiene, sanitation, and proper food storage were also crucial factors in maintaining the health of the crew during long sea journeys. Additionally, while cats were beneficial in controlling rodent populations, they could themselves carry certain diseases, so maintaining their health and preventing overpopulation was necessary to ensure their positive impact on the ship's environment.
