In Europe more than 1,000 years ago, cats were used both as pest control and as a source of fur. When a group of Scandinavian archaeologists compared the size of cat pelts from the time of the Vikings to the bodies of modern-day kitties, they found that 21st-century cats were 16 percent larger.
What made these results so unusual is that domestication usually shrinks an animal. Dogs are a quarter smaller than wolves; livestock animals, such as cattle, and goats, are also smaller than their wild counterparts.
And it’s not just the availability of energy-dense kibble that has led to bigger cats. Scientists have also documented larger body sizes in free-roaming and wild cats in the Australian bush. Although those cats might steal human food scraps, they aren’t all being regularly fed by people.
But what kind of cat will they become? One possibility is that the cats of the future will be larger than today’s types.
Continued contact with humans may also help cats grow friendlier. By nature, cats tend to be more solitary and standoffish(不友好的) than dogs, which have a long evolutionary history as pack animals rather than lone hunters. Ongoing contact with humans may have helped give friendlier cats a survival advantage, making them more likely to pass on more sociable genes to their offspring.
Over time, this might have helped create a more relaxed pet—without ruining one of the most endearing parts of living with a cat: that when your kitty cuddles, you know it’s for real.
As humans spend more time learning about cat psychology and behavior, this effort creates an opportunity to improve our relationship. By understanding what makes cats tick—what motivates them, what makes them happy, what they can and can’t tolerate— we can ensure that our cats have the best lives possible.
