How did cats become pets?

Cats around the world are among the most popular pets today. The history of cats and humans derives back before they were even domesticated. Unlike dogs, however, we can more confidently trace cats to the region of their domestication, namely the Middle East. By at about 80000 BC, Felis silvestris, a wild cat species, became the origin of what became the domesticated cat (Felis catus). Because cats have evolved relatively little from their wild ancestor, we can understand their development in the Middle East and beyond more clearly than dogs.

Domestication and Early History

Anatomically, it is difficult to distinguish wild and domestic cats. In fact, in early Neolithic societies even before 8000-7000 BC, it is possible or even likely wild cats or early domesticated cats would have lived in villages. They may have simply stayed near villages rather than been actively domesticated initially, which may explain why their anatomy has not changed. In effect, cats could have been one of these rare species that could have domesticated itself as it adapted to humans through its own choice.

One recent study has suggested that farming in China, by around 30000 BC, could have also led to the rise of domesticated cats. This could have been a second wave of domestication. Similar to the Middle East, cats may have simply hung nearby villages as they developed, where cats adapted themselves to villages. A local variety of wild cat, Felis silvestris ornata , seems to be the likely candidate if local domestication also occurred in China. The presence of mice and rats, which would have been attracted to agricultural products produced in early villages, could have attracted cats to villages. In effect, a type of ecosystem of predators and prey developed around agricultural being brought in from fields. The fact that domesticated cats are still relatively agile hunters, and often live relatively independent of humans, also suggests that humans probably only played a passive role in their domestication.

Rise of Cat Pets

While the transition of wild cats to domesticated cats appears to be relatively clear, particularly as agriculture became prominent around the world. Not surprisingly, we do find cat remains in Europe and other parts of Asia as agriculture became more established. However, it is less clear when humans began to actively let cats into their homes.

The earliest evidence of close contact between humans and cats comes from Cyprus from 7500 BC, where a human was found buried next to a cat. In ancient Egypt, by around 2000 BC, we find the first cat cemetery with mummified cats and tomb paintings showing cats. In fact, something on the order of 80,000 mummified cats have been found in the cemetery, making it still by far the largest known cat cemetery. The goddess Bastet was depicted as a cat and the association of cats with this goddess may have made cats sacred. However, from tomb paintings, it is also clear that the Egyptians had an affinity and care for the cats, suggesting that cats by then were now more intertwined with daily life and people actively took care of cats.

One hypothesis is that cats, even in the wild, act docile to humans and sometimes even act playful. This suggests that the natural nature of cats could have led them to being invited to people's homes as their presence in agricultural villages and towns became more established.
