See The World Through The Eyes Of A Cat
Vision in Cats and Humans
The last common ancestor of humans and cats was a mammal that lived over 90 million years ago. One set of descendants of this mammal branched into rodents and primates, eventually giving rise to us. The other branch led to cats, as well as whales, pigs, horses, and bats. For one thing, this means we humans are more closely related to mice than we are to cats.
