Cats may have been domesticated to control the spread of mice

Tom and Jerry have been at it for millennia! First domestic cats appeared in Europe almost 10,000 years ago as mice spread across the continent, study reveals

  • Cats may have been domesticated to control the spread of mice, a study finds
  • Mice grew along with agriculture, cities and trade and domestic cats followed
  • The house mouse is all over the world making it the most invasive rodent species

Europe’s first domestic cats appeared around the same time as mice spread all over the continent, a study shows. 

The study said that humans’ domestication of cats in Europe may have been to try and control the spread of mice to protect grain and food stocks.    

It looked at eight countries, including Britain, and found that human society has facilitated the spread of the mouse over the last 20,000 years.  

The house mouse is widespread throughout the world today, making it the most invasive rodent species.  

A study from the French National Centre for Scientific Research found that as mice spread around the world so cats were domesticated suggesting that cats were domesticated to help control the spread. Pictured: Stock photo of a cat and a mouse

Western Asia, Turkey and Egypt’s development in agriculture, 12,000 years ago,  fostered their mice population.

The team found that hunter-gatherers in the Eastern Mediterranean region of Western Asia kept a a ‘commensalism’ relationship with mice where they were happy for mice to prosper without getting anything in return. 

Commensalism is a long-term relationship from which one of the species benefits  but the other species is neither benefitted or harmed.  

But mice only spread around eastern Europe 6,500 years ago and southern Europe 4,000 years ago.

The more urban Europe became and more it became involved in trade the more mice were able to survive which may have been why humans kept cats around. 

French National Centre for Scientific Research study leader Dr Thomas Cucchi said that although people think of rats as invasive rodents mice have been much more successful at it.   

Dr Cucchi said that studying where mice were able to spread was essentially studying where domestic cats followed.  

Domestic cats have been chasing mice around the world for tens of thousands of years making both of them just as present as each other in almost every human society.
