You can see more clearly than your feline friend, but cats win when it comes to night vision. 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.īut you still have one visual advantage over your furry friend: Humans have better visual acuity, or clearness of vision, than cats, reports Business Insider. Goldstein, chief medical officer at the Animal Medical Center in New York City, tells the New York Times. "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. They also see the world mostly in shades of gray, which is perfect for low light. A cat's vision is very powerful because of the strategic shape and movement of their eyes. Observe your kitty: Their pupils will constrict in the bright sunlight and then dilate in the dark. A human's round pupils are no match for vertically slit pupils. How well do cats see in the dark? Much better than their pet parents. 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. The scientists at UC Berkeley also found that animals with slit pupils tend to be lower to the ground than animals with round pupils. Not much has changed, except that house cats don't have to work as hard to get a meal. Your cat's ancestors were solitary hunters. In contrast to animals whom the researchers refer to as "active foragers," ambush predators are active during both day and night. Researchers at the University of California, Berkeley found that animals that have vertically slit pupils, including cats, are more likely to be ambush predators. 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. They don't, but it can seem that way when your cat wakes you up for a midnight meal. 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. This extra light helps them to see in the dark. As American Veterinarian explains, cats' large corneas and pupils, which are about 50% larger than humans', allow more light into their eyes. They can see very well in low light, however - a skill that gave domestic cats' ancestors an advantage over their prey.
But can cats see in the dark? And if they can, how well do cats see in the dark? Can Cats See in the Dark?ĭo cats have night vision? Not exactly. The idea that cats have night vision contributes to their elusive aura. Although humans domesticated cats nearly 12,000 years ago, your feline friend is still somewhat of a mystery.
