Are Cats Color Blind?

Like most cat owners, you probably have a basket full of colorful cat toys. But do you ever wonder if your feline fella can even see colors? Are cats color blind like dogs? Do cats only see in black and white? How do they see the world around them?

Do Cats See in Black and White?

It is widely believed that both cats and dogs see in black and white. But that’s not the case. While it is true that cats cannot perceive the rainbow’s colors just like humans, it does not appear entirely black and white to them. Actually, both cats and dogs can see colors­ but quite differently from humans. Where exactly does the difference lie? How is cat vision different from human vision?

Cat Vision Vs. Human Vision

Humans are trichromatic. We have three different cone cells in our eyes, letting us identify red, green, and blue combinations. Like humans, cats are also trichromatic. But despite being trichromatic, cats’ vision is quite different from humans. This is because of the variation in the numbers of light rods and cones present in human and cat’s eyes. According to VCA hospital, cats have 10 times fewer cones than humans. The cats’ inability to differentiate between colors is due to the lower number of cones in their retina.

The higher number of rods compensates for the lower number of cones in cats. Where cones have a duty of identifying colors, rods detect light and motion. The higher number of rods gives cats an edge over humans when it comes to night vision or seeing in dim light.

In addition to the difference in the number of cones and rods, cats are also short-sighted. They can only see objects clearly within a range of 20 feet. In contrast, humans can clearly see as far as 100 to 200 feet.

Another difference between cat vision and human vision is in their peripheral vision. The human eye is designed to offer only a 180-degree wide view, cat eyes are programmed to enjoy a 200-degree wide view.

Are Cats Color Blind?

No Cats are not color blind—meaning they do not see the world in black and white.

Cats’ vision is similar to color-blind humans. They do not perceive the full range of colors. Even the colors that cats tend to perceive are not “truly” appreciated by them—they appear to be washed out. This is because of the lower concentration of cones in cat eyes.

As discussed earlier, cats have very few cones as compared to humans. This is the reason that many people tend to wrongly believe that cats are color blind.  But cats are not color blind—they see colors but are not as vibrant as humans do.

Which Colors Can Cats See?

Years of research have established that cats are not color blind. But it doesn’t mean that they see in black and white; they do see colors. But there is still no clear answer to “what colors can cats see?”

While some scientists and vets believe that cats can only see shades of blue and grey, others argue that cats can also perceive yellow and green. However, it is confirmed that they cannot perceive pink or red hues.

Do Cats Have Night Vision?

Watching your cats roam around and be active at dawn and dusk, you may wonder can cats see in the dark. If yes, how well can cats see in the dark? Are cats nocturnal?  

Are Cats Nocturnal?

No! Cats are not nocturnal. Are they diurnal? No, they are not diurnal either. Actually, cats are crepuscular beings. This means that their circadian rhythms dictate them to sleep throughout the night and day and be active at dawn and dusk. They usually hunt at dawn or dusk.

Can Cats See in the Dark?

Yes, cats can see in the dark. But can cats see in complete darkness?

No, cats cannot see in complete darkness; they need some level of light—dim light—to be able to see. They see well in dim lights, during twilight—at dawn and dusk. They only need one-sixth of the amount of light as compared to humans to be able to see. This means that cats can see well with the moon out or a really dim-lit lamp in the room.

How Do Cats See in the Dark?

Noticing your cats easily swerving through a cluttered room without hitting anything, you may wonder how can cats see in the dark when they cannot even differentiate between colors and the whole world appears blurry to them.

Let’s discuss how can cats see in the dark—dim light?

As discussed above cats have a higher number of light rods in their eyes, which plays a role in enabling them to see in the dark. These light rods are responsible for detecting light. They also make cats detect motion in dim lights. Cats’ ability to see in the dark is furthered by the presence of a unique material, tapetum lucidum, in their eyes.

According to Dr. Cynthia Powell, tapetum lucidum acts as a mirror and reflects the light passing through the retina, brightening the view for them. Tapetum lucidum is also responsible for making cat eyes glow in the dark when light falls upon them.

Moreover, cats also have elliptical pupils that allow them to capture the maximum light, bettering their night vision. It is due to all these qualities that cats’ night vision is twice as efficient as dogs.

Combined with the night vision, higher motion-detecting capabilities in low light make dawn and dusk perfect hunting times for cats.

Can Cats See in Ultraviolet?

While the human eye is designed to block ultraviolet (UV) light, many animals’ eyes are designed to see in UV light. UV light passes through the UV-transparent lenses of these animals and hits the retina, where it is converted into nerve signals and sent to the visual system in the brain. As per research, in addition to cats, many other animals such as dogs, ferrets, and hedgehogs can see in UV light.

Are Blue-Eyed Cats Blind?

Have you heard this rumor? How about this one: “white cats are prone to blindness.” Well, the good news is, none of these is ‘entirely’ true. But the sad news is that having a white coat increases the chances of deafness in cats, especially when they have blue eyes. According to research, 17 to 22 percent of white cats with non-blue colored eyes are born deaf. The incidence of deafness jumps to 40 percent when white cats have one blue eye. And the probability of deafness shoots up to 65 to 85 percent when white cats have both blue-colored eyes.

What Does This Mean for You and Your Cat?

Knowing your cat cannot perceive the vibrant colors of the rainbow, you might be feeling sorry for your cat. But don’t. Their superior eye vision compensates for their impairment. However, it would help if you considered which colors a cat can see while shopping for cat toys and other products for your cat.

You should only buy those products with colors that a cat can easily see, such as blue, grey, and yellow. Similarly, you can avoid buying products featuring red or pink colors.

A simple answer to “are cats color blind” is, a cat vision is like that of a color-blind human, and even the colors they do see appear washed out to them.

Now that you have learned are cats color blind or not, maybe you want to take a look at can dogs see color.
