Thankfully, the cats that hung around human homes in search of rodents weren’t lions or tigers. They were smaller and less aggressive relatives, called wildcats. And the wildcats that were comfortable around people were even less aggressive than other wildcats.
Sometime between 10,000 and 9,000 years ago, early farmers must have figured out that keeping these creatures close kept stored food safe from pests. Some people likely started leaving out scraps of meat to make sure the wildcats would come back.
These tamer wildcats, now cared for by human friends, survived for longer than other wildcats. They had tamer kittens. As time went on, each new litter of kittens was tamer than the last. This process, called domestication, slowly changed wildcats into calmer, friendlier creatures. Wildcats stopped being so wild.
Humans soon realized that felines didn’t just protect food. In East Asia, cats were prized because they kept rodents from chewing early books, known as scrolls. Ancient Egyptians honored cats in their religion because they chased away dangerous snakes, in addition to keeping birds from pecking at grain fields. Beloved cats were even turned into mummies and buried alongside kings in their tombs.
By the early 1600s, cats had spread to nearly every corner of the planet. This was a time when huge ships were sailing around the world. Explorers and merchants would bring cats on board to keep their food—and crews—safe from rodents. Cats also provided much-needed cuddles and laughs on long, dangerous sea journeys. When the ships docked onshore, many cats trotted off to make new homes in different places. That’s how domestic cats came to America.
