Why do cats purr?

Cats have been purring at the side of humans for millennia, but the reasons for this soothing sound remain mysterious. A new study from the University of Kyoto may have found part of the answer: a gene associated with purring and vocalizations. Scientists analyzed the DNA and behavior of 280 domestic cats and found that those with a short androgen receptor gene purred and vocalized more, especially males. This gene, which influences testosterone-related behaviors, appears to be unique to domestic cats and likely emerged during their domestication. Big cats and even close relatives like fishing cats and leopard cats do not possess this long form. Interestingly, purebred cats more often carry the long-form gene, possibly because they are less reliant on vocal communication for their survival. Purring can serve multiple purposes – from seeking human attention to self-healing from injuries. Understanding these behaviors can help promote a stronger and happier bond between cats and their human companions.
