Cats see in color like humans but they are color blind like some color blind people. The most common form of color blindness in people is known as red/green color blindness. It is similar for domestic cats.
Cats eyes are designed to pick up movement in low light conditions because they mainly hunt at dusk and dawn, resulting in light sensitive eyes. However, their eyes focus less well resulting in a less sharp image and the cat registers colour less well.
Cats see “blue and yellow colors, but not red, orange or brown” (source: Popular Science). In a previous post on this subject I stated that cats were “red color blind or perhaps red-greed color blind”, which is more or less the same thing. However people are not sure how good a cat’s color vision is. In the past experts have stated that cats were colorblind.
We don’t know for sure how cats see things. We don’t know how their brain translates or reads this ‘color blind’ image. It may compensate for all we know.
To summarise, in plain language:
| PROPERTY | CAT | HUMAN |
| Colour | Weaker colour than humans, can’t see red, orange or brown or red or are red/green color blind | Good colour – better than cat |
| Peripheral | Very good 200º | Less good than cat at 120-180º |
| Sharpness | Average – worse than human | Good – better than cat |
| Night vision | Excellent – much better than human | Much worse than cat |
