Does Your Cat See the World in Black and White? The Surprising Truth About Feline Vision


Color blindness, or the inability to perceive certain colors, is common in cats. Cats have a limited color range compared to humans – their world consists mainly of blues, grays, and yellows. Unlike complete color blindness, where an animal can only see in black and white, cat color vision is just less vibrant than human sight.

In this article, we’ll cover the anatomy behind feline color vision, signs your cat may be colorblind, how to test for it, and how to enrich the life of a cat with limited color perception. While cat color blindness is normal, there are still things owners can do to compensate.

Anatomy of Feline Eyes

Cats have a number of specialized structures and adaptations that allow them to see well. Their eyes contain a retina which houses photoreceptor cells called rods and cones that detect light and transmit signals to the brain. Cats have a high density of rods which excel at night vision (Source).

Another unique structure is the tapetum lucidum, a reflective layer behind the retina that reflects light back through the photoreceptors, improving vision in low light. Cats also have a third eyelid called a nictitating membrane that can move across the eye to protect it and provide additional lubrication (Source).

The feline eye has a lens that can change shape to focus light and a muscular iris that opens and closes to control light levels entering the eye. The cornea provides additional focusing and protection. Accessory eye structures like the conjunctiva and lacrimal glands produce mucus and tears to lubricate the eye.

Together, these specialized structures allow cats to see well in low light, detect rapid movement, and focus on near and far objects – adaptations suited for hunting prey.

Do Cats See Color?

Cats have a more limited color vision compared to humans. According to research by the Veterinary Centers of America, cats likely only see shades of blue and green (Daw 1970). This is because cats, like many other mammals, only have two types of color receptors (cones) in their eyes, while humans have three. The two cone types sense blue and green light (VCA).

This means cats do not perceive the full spectrum of colors that humans can see. Reds, oranges, and purples appear more muted and gray to cats. However, cats may still be able to differentiate between some shades in the blue-green range that humans cannot distinguish (Daw 1970). Their vision is similar to red-green color blindness in humans.

While cats cannot see the richness of color that humans do, their vision is adept at detecting movement and detail in low light conditions. Their eyes have a high density of rods, which are the light receptors responsible for night vision (VCA). So cats rely more on movement and brightness than color to hunt and navigate their environments.

Cat Color Blindness Tests

There are a few methods that have been used to test for color blindness in cats, but they are more difficult to perform compared to similar tests for humans.

One technique is the neutral point testing method. This involves training cats to discriminate between two colored lights, then adjusting the wavelengths to find the point where the cat can no longer tell the difference. The wavelength of this neutral point gives clues about the peak sensitivities of the cat’s color vision.

Researchers have also tested whether cats have a preference for bluish-purple light versus greenish-yellow light. Most cats prefer blue/purple, while cats with strong color blindness show no preference. This helps identify cats that may have issues with their color vision.

There are no standardized color blindness tests designed specifically for cats. But scientists have been able to adapt human test principles to discern whether cats can discriminate certain colors. Behavioral observation is also used to identify potential color vision problems.

Signs Your Cat May Be Colorblind

There are some behavioral signs that may indicate your cat is colorblind. Since cats can’t tell us if they are seeing colors properly, we have to look for clues in their actions and reactions to their environment.

One sign is if your cat has trouble finding toys or treats that blend into the background. For example, a green toy on green grass may be hard for a colorblind cat to spot. Or they may struggle to see treats you’ve tossed that match the color of the floor or furnishings.

You may also notice your cat startle at objects or movements that would be obvious to cats with normal color vision. A colorblind cat can fail to see things approaching in their peripheral vision if the color blends into the surroundings.

Some other signs include: bumping into objects, hesitation and caution navigating new environments, lack of reaction to laser pointers, inability to track moving objects smoothly, and clumsiness pouncing on prey or toys.

Overall, colorblind cats tend to be more timid, jumpy, and unsure in unfamiliar environments. Subtle visual cues humans and normal sighted cats take for granted simply aren’t visible to colorblind kitties.

Impacts of Color Blindness

Color blindness can have significant impacts on a cat’s everyday life and abilities. According to, color blindness affects how cats perceive visual information and recognize objects around them. It makes it more difficult for cats to differentiate between similar colors, especially shades of green, orange, browns, grays, and blues.

This means colorblind cats may struggle to find certain toys or objects in environments with low color contrast. For example, a green toy on a brown rug may be hard for them to distinguish. Colorblind cats are also slower to recognize familiar objects compared to cats with normal color vision.

Additionally, colorblindness may impact social interactions between cats. Visual cues like eye contact and body language rely partly on subtle color changes that colorblind cats cannot pick up on as easily. This could lead to misunderstandings and difficulties reading other cats’ signals.

Overall, while colorblindness in cats does not severely disable them, it can reduce visual acuity and information that helps cats efficiently navigate environments and social settings. Understanding these impacts allows owners to better accommodate colorblind cats’ needs.

Living with a Colorblind Cat

Caring for a colorblind cat is very similar to caring for a cat with normal vision. However, there are some tips that can help enrich the lives of colorblind cats.

According to PetAssure, use mats, carpets, and rugs with different textures in areas around your home. The different textures will help the cat navigate and identify important areas like the litter box, food bowls, and scratching posts. You can also place scents around the house to help identify areas.

It’s also important to keep furniture and layouts consistent so the cat can memorize the environment, according to Cat Behavior Associates. Avoid rearranging and make sure to keep pathways clear. Provide ramps or steps to access furniture if needed.

Engage your cat’s other senses by offering toys with bells, crinkle material, catnip, etc. Food puzzle toys can also provide enrichment. Grooming, petting, and gentle brushing are soothing. And make sure your cat has access to sunny spots or outdoor enclosures to experience new smells and sounds.

While colorblindness doesn’t require specific treatment, understanding your cat’s needs helps provide a safe, engaging environment.

Enrichment for Colorblind Cats

Even though colorblind cats can’t see colors the same way humans do, they can still lead happy, enriched lives. The key is providing them with stimulating toys and activities that engage their other senses like smell, touch, taste and hearing.

Certain types of toys are well-suited for colorblind cats:

  • Scented toys – Toys infused with catnip or other strong scents appeal to a cat’s powerful sense of smell. Catnip mice, balls filled with dried catnip or silvervine powder, and kicker toys with catnip are excellent choices (
  • Textured toys – Look for toys with different textures like fur, feathers, crinkle paper, or soft plush that provide sensory stimulation for pawing and chewing.
  • Treat puzzles – Food puzzles encourage cats to use their nose, paws and problem-solving skills to get treats out. They provide mental stimulation and slow down feeding time.
  • Crinkle balls – Lightweight balls that make noise when batted around are ideal for blind cats to chase and locate by sound.

In addition to interactive play, creating scent trails around the home with toys dragged in essential oils or dried spices allows blind cats to exercise their sniffing skills. Placing platforms, perches and scratching posts around the home also enables more climbing and exploration.

While colorblindness presents some challenges for cats, thoughtful toy and activity choices tailored to their remaining senses let them live an active, engaged lifestyle.

Should You Get a Colorblind Cat Tested?

While it may seem concerning to think your cat may be colorblind, there are pros and cons to getting a formal diagnosis. Some reasons you may want to get your cat tested include:

Peace of mind knowing for certain if your cat struggles to see colors. According to[1], some signs your cat may be colorblind include not responding to colored toys or having difficulty following a laser pointer. A color vision test can confirm if this is due to color blindness.

Ability to make accommodations. If you confirm your cat is colorblind, you can tailor their environment, toys, food bowls, etc. to suit their vision needs. For example, choose toys in high contrast colors.

On the other hand, there are also reasons you may choose not to test:

Cats adapt well. According to Spot Pet Insurance[2], colorblind cats can live normal, enriching lives. Their other senses compensate, so colorblindness may not impact their quality of life.

No “cure” exists. There is no treatment to restore color vision, so a diagnosis does not change medical options. You can enrich their life just as well without an official diagnosis.

The decision is personal and depends on your cat’s unique needs. Consult your vet to determine if testing makes sense for your feline companion.


In summary, while cats do see some color, their vision is more muted compared to human color perception. Cats have a limited range of color vision due to having only two types of cones in their eyes. As a result, cats can get confused by certain colors, like red and green, and have difficulty seeing contrast and details. There are ways to test for cat color blindness, but the condition doesn’t significantly impact most cats’ lives. To enrich a colorblind cat’s environment, use colors with high contrast, utilize smells and textures, and ensure their space is safe. While color blindness in cats can’t be cured, you can help them live full, enriched lives by making a few adjustments to their home and playtime activities.

The key takeaways for living with a colorblind cat are:

  • Use high contrast colors like black and white for toys or litter boxes.
  • Add textures and scents to toys to increase sensory stimulation.
  • Ensure their environment is safe by avoiding clutter, sharp objects, or anything hazardous.
  • Switch out toys frequently to prevent boredom.
  • Consider food puzzles or treat balls to engage their senses.
  • Play games that utilize smell and hearing like hiding treats.
  • Don’t rely solely on laser pointers for play, provide tangible toys too.
  • Give them access to elevated perches for enriched viewing.
  • Overall, focus on providing a stimulating home through all senses, not just vision.

While a colorblind cat may face some challenges in navigation and play, there are many ways to enrich their life. With some simple adjustments, you can help your colorblind cat live happily and healthily.
