For all ages, people have debated the differences on whether cats are better than dogs. Now scientists have proof that cats really are better than dogs — from an evolutionary perspective.

A groundbreaking study of 2,000 ancient fossils reveals that felids – the cat family – have historically been much better at surviving than the “canid” dog clan, and often at the latter’s expense. In other words, cats are better survivors than dogs and have no qualms killing off dogs to insure their own survival.

If the idea that cats would selfishly sacrifice others for their own benefit sounds shocking, then you probably haven’t spent much time living with a cat. To learn more about this scientific study proving that cats are better than dogs at surviving, click here.
