Cats See Things We Can’t–But Often Can’t See What We Can

Cats are color-blind, and most people think they can’t see any colors except black, white, and gray. They’re wrong.

Cats can see a few colors, like green and blue, but a proven study shows that cats (and dogs!) could not identify the difference between red and green.

The reason for this is that in daylight, living things need certain kinds of cells, called cones, to see different colors. Humans have three kinds of cones to see red, blue, and green. Cats, however, have only two kinds of cones, which enable them to see blue and green, but not red.

Yet they aren’t missing out on everything. They are nocturnal. However, contrary to the myth that they can see in perfect darkness, in truth they can’t. Actually, they require only at least 1/6 of the light humans need to see, making their night vision a lot better than ours.
