Cat-Human Bond May Go Back More Than 5,000 Years

Researchers detect a mutually beneficial relationship

WebMD News from HealthDay

MONDAY, Dec. 16, 2013 (HealthDay News) -- They may not hold the title of "man's best friend," but domesticated cats have been purring around the house for a long time.

Just how long? New research points back at least 5,300 years, at which point felines needing food and humans needing rodent killers may have entered into a mutually beneficial relationship.

"We all love cats, but they're not a herd animal," study co-author Fiona Marshall said. "They're a solitary species, and so they're really rare in archeological sites, which means we just don't know much about their history with people."

New scientific methods enabled Marshall's team to show what led to cats' domestication, she said. While dogs were attracted to people living as hunter-gatherers 9,000 to 20,000 years ago, it looks like cats were first domesticated as farmer's animals, she said.

"Cats had a problem [obtaining] food, and so were attracted to our millet grain. And farmers had a problem with rodents, and found it useful to have cats eat them," said Marshall, a professor of archaeology and acting chair of the anthropology department at Washington University of St. Louis. The findings are published in the Dec. 16 issue of the Proceedings of the National Academy of Sciences.

The authors point out that although cats are one of the most popular pet species in the world, information regarding the timing of their domestication has been sparse, based primarily on Egypt artifacts that date back about 4,000 years and show the animals were home dwellers then.

Additional anthropological evidence of the connection had also been unearthed in Cyprus, the team notes, suggesting some form of close contact (although not necessarily domesticity) dating back roughly 9,500 years. But an inability to connect the dots between these two periods has frustrated researchers for years.

The current revelation stems from an analysis of eight cat bones, attributed to at least two cats, unearthed near a small agricultural village known as Quanhucun in Shaanxi province, China. The cats were described as similar in size to domestic cats found today in Europe.
