Are cats “colorblind”? Let’s explore the world through a cat’s eyes!
Are Cats Colorblind?
The cells in our eyes that perceive light and affect vision are called photoreceptors, which are divided into cone cells and rod cells. Cone cells primarily help to distinguish colors, while rod cells are mainly responsible for sensing light and movement.
Humans have three types of cone cells, allowing us to perceive combinations of red, green, and blue colors. Similarly, felines also have three types of cone cells, but due to the underdevelopment of their red cone cells, cats mainly see colors such as blue, green, yellow, and gray.
Color Differences
Cats' visual systems differ from those of humans; they have fewer cone cells in their retinas, which means they are less capable of distinguishing colors. Nevertheless, cats can still perceive some colors and have particular preferences. Blue and green are the most vivid colors for cats, while yellow and purple can also catch their interest, although these colors may not appear as bright and saturated as they do to humans.
How to Choose Pet Supplies Correctly?
When purchasing toys for your cat, remember that their eyes are most sensitive to yellow, green, and blue. For example, compared to a red yarn ball, your cat may be more inclined to scratch a yellow or blue sofa. If your cat shows no interest in a red wand toy, consider trying a toy in yellow or green.
Compensating for Colorblindness with Other Senses
Not only are cats "colorblind," but research indicates that they are also nearsighted. When looking at something from 100 meters away, humans may see it clearly, while cats can only see clearly within about 20 meters.
Although cats do not possess the ability to appreciate the colorful world as we do, they have visual advantages that humans cannot match. Compared to humans' typical 180-degree field of vision, cats have a wider field of about 200 degrees. Additionally, cats possess remarkable night vision capabilities, allowing them to spot even the slyest mouse under low light conditions.
