How the world looks from the perspective of a cat – Cats.com

The eyes of cats are structurally different from ours, built to facilitate the hunting of small dams with dim light. These predators can detect a small insect of the house and detect a laser pointer through the corner of the eye. So why do you miss a delight when you are right next to your legs? What do our cats really see while looking at the world around them?

Key control
Cat Vision is different from human view, including differences in its night vision, peripheral vision and long distance view.
Cats do not see the same colors as us, probably seeing less variation and tones much more turned off.
Cats use other senses along with the vision to “see” the world, including hearing, aroma and tactile mustaches.
How are cat’s eyes different?
Do cats see the same colors, brightness and contrast as humans? Probably not. Anatomical variations between human eyes and cats mean that they see the world a bit differently. The size and shape of cats are designed for their habits and surroundings. Cats have elliptical pupils that can narrow themselves to vertical clefts. This is used for depth perception and distance control, which is essential for hunting.
Cats have a third eyelid (or nication membrane) that rests on the front of the eye. It can sweep through the surface of the cornea, washing dirt and debris. Another difference is in the retina on the back of the eye, which contains the light receptors that turn the light into vision. These cells are called “rods” and “cones”. Cats and humans have them, but in very different proportions.
Much of the anatomy and physiology of a cat are designed for its evolution as natural hunters. They are mandatory carnivores with sports limbs, an excellent sense of smell and the ability to drag in silence through the landscape.
Newborn kitten vision
Did you know that cats of cats are always blue during the first weeks of their life? The first vision of the world of a cat is when his eyes open around 8-12 days. It is likely that your kitten will see a blurred version of your surroundings at this early stage, since your vision is not yet fully developed.
His students are also learning to expand and contract in response to the light, so keep them away from bright light. As the kittens become more active and alert, beginning to explore their new and exciting world, their vision also improves.
Low light conditions
The vision of a cat adapts to see well in low light conditions, which makes them excellent hunters of dusk and dawn. Shuttersock.com
Cats are more active at dawn and dusk, the perfect moment to find small dams. Therefore, his eyes are well adapted to the dim light, with a high number of rod receptors that improve their night vision beyond ours.
They also have a “tapetum lucidum”, a reflective layer just in the back of the eye that gives small amounts of light a second opportunity to hit those important photoreceptors, which turn the light into a vision.
Short distances
The behavior of feline hunting generally implies the stealthy stalking of the dam, which leads to a final jump made at a short distance. Cats have little need for long distance vision, and they can probably only see about 20 feet in front of them.
Nor can they see very well at very short distances, since the muscles that control cat pupils cannot focus close vision. Cat Vision is more acute in around that 20 -foot brand, with closer objects and further from that probability that blurred and unfocused is seen.
Peripheral vision
Human eyes have a visual field around 180 degrees. Cats have a wider field of vision at around 200 degrees due to a greater number of bar cells. The feline eyes are oriented forward, but this broader peripheral vision helps them see a higher range of the surrounding landscape, useful for detecting small dams.
Do cats see in color?
Now we know that cats see well with dim light and distances of about 20 feet, but with a quite wide periphery of the view. But is this slightly blurred vision of the world that is seen in color by cats?
The vision of color between animals varies greatly and depends on the type and number of cone cells present in the retina.
Humans have three types of cones, which allows us to see red, green and blue. Some species of fish and birds have four types, which allows them to see the light in the ultraviolet spectrum. Other animals, generally nocturnal such as mapaches, have a poor color vision because they only have a photopigment. Other mammals, such as dogs and horses, have two types of cones, and can see violet blue light but cannot differentiate yellow-green or red light, similar to people who are red-green daltones.
Cats fall somewhere in the middle of this spectrum. Like humans, they have three types of cones, but they have much less than us. The exact consequence of this is very debated, but it is likely that cats do not see the same richness of the tones we make. They also probably have a reduced color spectrum. Recent research He has raised the hypothesis that cats look more like people who are red.
See the world through the senses
Cats trust much more than in their sight to navigate the world: they also have sensitive, listeners and sense of smell.
When we talk about how we see things, it is easy to assume that we are talking only about vision. For us humans, vision is a main sense. It is of great importance for our daily lives.
As we have already seen, the vision is also important for cats, and their view is particularly well adapted to their lifestyle. However, cats also use their other senses to navigate the world that surrounds them.
Whiskers
Cats use their mustaches as a tactile vision system, helping them to ‘see’ their immediate environment. Bigotes are useful for both balance, spatial consciousness and navigation, essential to negotiate difficult situations, such as narrow spaces.
Scent
Cats have an excellent sense of smell. With more than 200 million aroma receptors in those beautiful noses, more than forty times more than humans! – It is not surprising. It is possible that your cat cannot see far in the distance, but they can certainly capture much more subtle aroma clues than us. This helps them understand the world that surrounds them.
Audience
Another very perfect sense in our feline companions is your audition. Cats can listen to sounds four to five times further than humans. You can also listen to a higher range of sounds. They are particularly in tune with acute sounds (imagine a mouse squeak) and can distinguish the sounds that are made only a few inches from each other.
Cats see the world well
So how do cats see the world? Exactly how they are supposed to. With its vision adapted to short -ran -ranking prey in faint light and other senses prepared to navigate their immediate surroundings, cats are the best hunters. The most active at dawn and dusk, our beautiful cats can sleep during the day, when vibrant colors and bright lights do not work for their advantage.

Frequent questions
How do you see the vision of cats?
The view of cats is well adapted for low light conditions with a wide peripheral field of vision, but also with the inability to see long distances. They also see a reduced color spectrum that is different from ours.
Can cats see how humans do?
The vision of a cat varies from that of a human in several ways. Cats can see better in low light than us and have a broader peripheral vision of vision. However, they are not good to see long distances and can see much less vibrant colors than humans.
Why do cats look at you?
Cats can look at you when they want something, when they are curious about what you are doing, when they are scared or stressed, or on the contrary, when they feel relaxed and sleepy. If they give you a slow blink while looking at, this is a sign of affection and trust.
