What Do Cats See in the Dark?

Although humans domesticated cats nearly 12,000 years ago, your feline friend is still somewhat of a mystery. The idea that cats have night vision contributes to their elusive aura. But can cats see in the dark? And if they can, how well do cats see in the dark?

Researchers at the University of California, Berkeley found that animals that have vertically slit pupils, including cats, are more likely to be ambush predators. They concluded that vertical pupils help shorter animals estimate how far away their prey is an advantage that much larger cats, like tigers and lions, don’t need.

Can cats see in total darkness?

The truth is that cats cannot see in absolute darkness any more than we can. However, they are much better adapted than humans for seeing in low levels of light. … Third, cats have an extra “mirror” layer at the back of the eye behind the retina, which means that the incoming light has two chances to hit the rods.

Can cats see TV?

Unlike dogs, who seem less interested in TVs overall, cats have a super keen sight. They can take in imagery much faster that even humans can. This means that they can see modern TV screens, which show images much faster than old TV screens.

What do cats see when they look at humans?

When cats look at humans, they see another large cat lacking balance and agility. With limited cones and many rods, cats are colorblind (may not see you well in bright lights), near-sighted (see a blurry figure when you’re 20+ feet away), and struggle to identify their human’s faces 50% of the time.

Can cats see 100% in the dark?

Though they can’t see in 100% darkness, cats can pick up on the smallest bits of low light to color in a space and move through what, to humans, seems dark. Outside that low lighting is often moonlight. Indoors or in a city there are more than enough devices and reflective surfaces to illuminate a cat’s vision.

If you are a cat owner you may have had the wonderful experience of waking up in the middle of the night to hear your kitty destroying the throw rugs or hissing loudly at some mystical being outside the window (or at your homes friendly ghost). These adorable, albeit sometimes annoying, nighttime antics would suggest your cat can see incredibly well in the dark and might be nocturnal.

One thing I think about when considering feline (night) vision is their tapetum lucidumor a thin, reflective layer along the back of their eye that ‘bounces’ and magnifies light in dark places. This is the reason why dogs and cats‘ eyes tend to ‘shine’ in the dark, says Alicen Tracey, DVM, veterinarian at Den Herder Veterinary Hospital in Waterloo, Iowa.

With their amazing eyesight, cats are especially good at detecting small movements and noticing fast details, even on moonless nights. Even though your cat appears subdued in the sun all day doesnt mean he isnt an expert huntsman once he finally decides to move.

Cats are notorious night owls, so we’ve long thought that they have excellent night vision, but is this actually true? Find out everything you need to know about your cat’s night vision with our guide.

Cats have more rods which are responsible for night, peripheral vision and motion sensing, whereas humans possess more cones which make them better at seeing colours and daylight. You may have often wondered why your cats eyes are mostly a straight vertical line during the day, then expand at night or when theyre feeling playful.

This is because when their pupils are vertical slits it allows them to focus, as varying amounts of light can enter the eye through different areas. According to a study by the University of California in 2015 , when a cats pupils dilate to their adorable saucer like state, more light is allowed to enter the eye.

You may have noticed your cat sleeping on a couch in a nice patch of the sun during the day but in the evening, your same cat is extremely active running around the living room. Contrary to popular belief, cats arent nocturnaltheyre actually crepuscular, meaning theyre most active at dawn and dusk, which is just one of these 21 fascinating cat facts. But how are cats able to see so well at night? Can cats see in the dark?

In a study by the City University London, the slit-shaped pupil was most often found in animals that hunt by day and by night, and especially among predators that ambush their preyincluding cats, snakes, and crocodiles. Youre unable at that time to shrink your pupils down to focus. Here are 9 true stories that prove animals feel the same emotions that we do .

Can Cats See in the Dark?

Do cats have night vision? Not exactly. They can see very well in low light, however — a skill that gave domestic cats‘ ancestors an advantage over their prey. As American Veterinarian explains, cats‘ large corneas and pupils, which are about 50% larger than humans’, allow more light into their eyes. This extra light helps them to see in the dark.People’s homes are rarely in complete darkness — there’s always a little light coming in from somewhere — which is why humans think their cats have night vision goggles. They don’t, but it can seem that way when your cat wakes you up for a midnight meal. Cats actually aren’t nocturnal; they are crepuscular creatures that hunt at dusk and dawn, the time of day when many other animals (i.e., prey) become more active. Talk about perfect timing.

Evolution of Cat Night Vision

Researchers at the University of California, Berkeley found that animals that have vertically slit pupils, including cats, are more likely to be ambush predators. In contrast to animals whom the researchers refer to as “active foragers,” ambush predators are active during both day and night.Your cat’s ancestors were solitary hunters. Not much has changed, except that house cats don’t have to work as hard to get a meal. The scientists at UC Berkeley also found that animals with slit pupils tend to be lower to the ground than animals with round pupils. They concluded that vertical pupils help shorter animals estimate how far away their prey is — an advantage that much larger cats, like tigers and lions, don’t need.

Cats vs. Humans

How well do cats see in the dark? Much better than their pet parents. A human’s round pupils are no match for vertically slit pupils. Observe your kitty: Their pupils will constrict in the bright sunlight and then dilate in the dark. A cat’s vision is very powerful because of the strategic shape and movement of their eyes. They also see the world mostly in shades of gray, which is perfect for low light.”A cat has the capacity to alter the intensity of light falling on its retina 135-fold, compared to tenfold in a human, with a circular pupil,” Dr. Richard E. Goldstein, chief medical officer at the Animal Medical Center in New York City, tells the New York Times. In other words, slit pupils give cats a big advantage over their humans when it comes to seeing in the dark because they’re much more effective at responding to how light enters their eyes.But you still have one visual advantage over your furry friend: Humans have better visual acuity, or clearness of vision, than cats, reports Business Insider. You can see more clearly than your feline friend, but cats win when it comes to night vision. With your combined visual abilities, you and your cat make the perfect team.

How Do Cats See the World?

Cats cannot see the array of pretty colors we humans can, but they can seeEver wondered why your cat seems confused by your new haircut or that mustache your wife begged you not to grow (was it worth it?)? This could be due their inability to see things clearly up close. Interestingly, cats also see things that are far away more blurry than a human would, but they beat us humans when it comes to a wider field of vision.Wanna see what a cat sees?

Can cats see in the dark?

The short answer is not exactly. Where it’s been widely thought that cat’s have their own built-in set of night vision goggles, they actually require at least some level of light to see. However, they only need one-sixth of the amount of light that humans do and can see in very low light.Cats won’t be able to see in the dark, in the rare event that absolutely all light is blocked out, but their sight is much more advanced than that of humans for all of their night time adventures.

Their eyes are intelligently designed

According to Catster, the reason cats’ night vision is so excellent is because of the intelligent design of their eyes. They possess a curved cornea and large lens, and in low light their pupils can dilate to full circles to allow in maximum light.Additionally, the photoreceptors in cats’ eyes are completely different to humans. Cats have more rods – which are responsible for night, peripheral vision and motion sensing, whereas humans possess more cones which make them better at seeing colours and daylight.The high number of rods in cats’ eyes also mean that they can see better in dimmer light, but they don’t see as well as humans in bright light.As well as that, cats have a tapetum, which is a reflective layer of tissue that reflects light back to the retina. This layer of reflective tissue bounces light back to the sensory cells, allowing the retina to receive more than 50% of the light available. The tapetum is also why your cats’ eyes seem to glow when you take a photo of them with flash or see their eyes reflected by headlights.

Their pupils expand for maximum light

You may have often wondered why your cat’s eyes are mostly a straight vertical line during the day, then expand at night or when they’re feeling playful. This is because when their pupils are vertical slits it allows them to focus, as varying amounts of light can enter the eye through different areas.According to a study by the University of California in 2015, when a cat’s pupils dilate to their adorable saucer like state, more light is allowed to enter the eye. This means they can see in low light situations, but it makes their vision blurrier. Additionally, cats can experience a 135 to 300-fold-change, whereas humans only experience a 15-fold change in the area. This means cats can adapt their eyes to see in a wider range of light levels than humans.

Cats are near-sighted

Where cat’s night vision is definitely much better than ours, they’re also near-sighted and can’t focus well on distant objects. Humans can be up to 5x further away to see something in the same amount of detail as a cat would see up close. Although cats’ vision is much blurrier, they have a wider field of vision of 200 degrees (humans have a field of vision of 180 degrees) for better peripheral vision. They are also better at picking up subtle movements and changes in light – such as a little shadow of a scurrying mouse.

Can cats see in the dark?

It might surprise you to know that though it may not seem like it, cats actually do need light, even a small amount, to see at night. “Cats only need about one-sixth (⅙) of the amount of light that humans do to see in low light situations, but like dogs, they are unable to see in complete darkness,” Dr. Katy Nelson, senior veterinarian at Chewy, tells

A cat’s vision

However, even though cats are able to see with less light than people doesn’t mean that what they’re seeing is clearer. “The other unique factor about cats’ eyes is their curved cornea, vertical pupil, and large lens. Their vertical pupils can expand up to 135-300 times (as compared to only 15 times in humans) in low light, or when they’re stimulated or feeling playful,” says Dr. Nelson. “This allows them to see better in a darker atmosphere, but things do appear blurrier with the pupil expansion.” These are the 13 silent signs your “healthy” cat is actually sick.

Can cats be near-sighted?

Like humans, cats can also have vision problems, like being near-sighted, meaning they can’t see objects that are far away clearly. For context, according to Purina, “Humans can be up to five times further away to see something in the same amount of detail as a cat would see up close.” However, even though cats are near-sighted, their peripheral vision of 200 degrees is wider than that of a person, which is 180 degrees. Here are 17 things your cat would love to tell you.

Why do cats have slit-shaped eyes?

The signature cat-eye shape is well-known in fashion and in nature but it has more uses than just aesthetics. “The slit-shaped pupil, with its incredible light control, is how a cat can hunt in near-darkness, and also in bright daylight,” says Dr. Nelson. “In a study by the City University London, the slit-shaped pupil was most often found in animals that hunt by day and by night, and especially among predators that ambush their prey—including cats, snakes, and crocodiles. Those that chase down their prey, like cheetahs and wolves, tended to have circular pupils.”
