In the past, it was understood that cats, like dogs, could only see in black and white. That may not be the case, though. Humans have three types of color receptors in the eyes, whereas cats only have two. Therefore, it is much more likely that they can see color, but in the way that color-blind people can see. Most of the difficulty in distinguishing colors in cats is between reds and greens. They can see yellows and blues very well, and they can see in the dark better than humans, too. Because of the position of the cat’s eyes, they do have a slightly wider field of vision than we do, but not as much as dogs.
However, as they are not as far round as dogs, cats have a better judgment of distances than dogs, which gives them the ability to be great predators. Along with that forward-facing view, they are very apt at hunting as their vision allows them to see even the slightest movements and hidden shapes. All in all, cat vision is blurry, slightly colorblind to reds and greens, but extremely acute to movements and shapes.
