You come back home after a long day at work expecting to chillout with the cat but instead, you find a dead carcass on your bedsheets。 And it搜狐财经’;s not the first time。 Sometimes it’;s small birds, other times rodents, maybe even some leftover chicken bones from last night’;s dinner。 Why do cats have to be such sadistic little devils?

Well, they’;re not actually evil at all。 They just think you’;re part of the family and that, frankly, you’;re a lousy hunter。

It’;s thought cats were first domesticated some 10,000 years ago, around the time humans started properly setting down, helped by agriculture and animal husbandry。 Having felines around proved helpful at warding off pests and, in time, they became affectionate household companions。 Just look at how a wild sand cat behaves when prey is near。 That’;s not to say, however, that cats are completely domesticated。

Unlike dogs, house cats still retained their predatory instincts and have a well-adapted carnivorous lifestyle。 To quote William Burroughs, ‘;The cat does not offer services。 The cat offers itself。’;

The fact that cats are so independent and self-reliant, often acting very smug, can be attributed to the fact that they’;re not really domesticated。 Scientists seem to agree nowadays that cats are merely tamed or semi-domesticated, and there’;s genetic evidence of back this up。 One study led by Wesley Warren, a geneticist at Washington University in St。 Louis, looked at the DNA sampled from several wild cats and breeds of house cats。 The analysis revealed that cats have diverged far less from their wildcat ancestors than dogs have from wolves。 The cat genome also shows little sign of artificial selection。
