The Real Reason Humans Domesticated Cats Is Darker Than You Think

Cats are among the most beloved companions on the planet, curled up in homes across every continent. A 2024 Cats Protection survey found that roughly 10.6 million people in the United Kingdom alone share their home with a cat, accounting for about a quarter of all households. On a global scale, the total pet population is estimated at around one billion animals, with cats sitting comfortably at the top as the world’s most popular pet. But the story of how they got there is stranger and more unsettling than most people realize.

For a long time, the widely accepted explanation for cat domestication was a fairly wholesome one. The leading theory held that African wildcats began wandering into early farming settlements more than 9,000 years ago, drawn by the rodents that gathered around stored grain. People tolerated them, then welcomed them, and over generations a mutually beneficial relationship formed. It made sense, it was tidy, and it painted cats as nature’s original pest control service.

Now a new study is challenging that version of events in a pretty significant way. Dr. Sean Doherty, an archaeological scientist at the University of Exeter and the lead author of the research, argues that the evidence simply does not hold up under scrutiny. His team reviewed available skeletal, genetic, and artistic evidence and concluded that true domestication actually began in ancient Egypt, somewhere between the second and first millennium BC. That pushes the timeline considerably forward and shifts the entire origin story to a new location.

Part of the problem with the older theory, according to Dr. Doherty, was the reliability of the dating methods used on cat remains. Cat bones can shift through soil layers over centuries, making them appear older than they actually are. His team used radiocarbon dating to verify the actual ages of remains and found that some specimens previously assumed to be ancient were considerably younger than researchers had believed. Speaking to BBC Science Focus, Doherty noted that their findings challenge the popular narrative in ways that are hard to dismiss.

So if cats were not primarily domesticated to hunt rodents, then what was the real driving force? The answer lies in religion, and it is genuinely unsettling. In ancient Egypt, cats were regarded as sacred animals closely associated with the goddess Bastet, and they were bred in enormous numbers specifically to be used as ritual sacrifices offered at her temples. This was not an occasional practice but an industrial-scale operation. Doherty explained that in temples dedicated to Bastet, archaeologists have uncovered millions of mummified cats, reflecting just how central this ritual was to Egyptian religious life.

The scale of it extends into more recent history in a rather shocking way. During the Victorian era, large quantities of these cat mummies were shipped to Britain, where they were ground up and used as agricultural fertilizer. What had once been a sacred offering in one of history’s greatest civilizations ended up spread across English farmland. It is a detail that puts a very different spin on the cozy image of a cat lounging by the fire.

The mass breeding required to supply temples with sacrificial animals is what researchers believe actually drove domestication. When you raise cats in large numbers across many generations, you inevitably begin selecting for traits that make them calmer, easier to handle, and more comfortable around people. That process, repeated at scale over centuries, is what gradually produced the domestic cat as we know it today. It means that the fluffy, independent, occasionally judgmental creature sharing your sofa may owe its entire domestic existence to one of history’s stranger religious practices.
