What Do Cats See? What Do Dogs See? Science Shows What the World Looks Like to Cats and Dogs

Have you ever considered what your pet perceives and how it differs from what we perceive? Learn how and why your pet sees the world.

What do cats see?” most pet owners wonder. “What do dogs pay attention to?” Is what I’m seeing the same as what you’re seeing? Humans perceive the world very differently than cats and dogs. To cats and dogs, the world appears slightly fuzzy, in shades of blue and yellow, with motion standing out more than anything else.


These significant differences in vision are caused by very tiny variations in anatomy. The retina, a layer in the back of the eye, collects light to be converted into images of the world by the brain. The retina is made up of rods and cones, with rods detecting predominantly dim light and motion and cones detecting mostly bright light and color. These cells have a significant influence on how each species views the world.

Shadows and light

Crepuscular cats and dogs hunted in the dim light of dawn and twilight, when their prey was also most active. As a result, both creatures obtained the capacity to see in low-light conditions. Cats’ eyes have six to eight times the number of rods as humans’, therefore they only need a sixth to an eighth of the quantity of light to see clearly. At night, dogs can see about half as well as cats, but four times better than humans.

Both dogs and cats have the tapetum, a layer of reflecting cells behind the retina. Light reflects off the tapetum and rebounds through the retina after passing through the retina, allowing the rods and cones to receive even more gentle. When cats’ eyes are touched by a powerful light source, this reflection causes them to glow in the dark.


Cats and dogs can see in the sunshine because they have exceptional night vision. Cats’ slit-shaped pupils allow them to adapt to almost any lighting scenario. The iris of a cat’s eye, which stretches and contracts to shrink or enlarge the pupil, is shaped like a figure eight and may close almost completely in bright light or open to almost 90% of the eye’s diameter in darkness. Humans, on the other hand, continue to have an advantage in daylight; cats have one-tenth the number of cones that humans do, implying that we see 10 to 12 times better in daylight.

Is it in full color?

It is not true that cats and dogs can only see in black and white. Some colors can be seen by your pet, while others cannot.

Cones distinguish three types of light sources: blue, red, and green. They see the same world as we see, but with different color ranges and motion depths. Dogs and cats, like people with red-green colorblindness, are unable to discriminate between the colors red, orange, yellow, and green.

This may appear strange because color is such a crucial part of how we perceive, but dogs and cats rely significantly more on their senses of smell and hearing than humans do, and they are far more interested in forms, brightness, and, most importantly, movement.”


The World Is Moving

Even the most laid-back dog or cat may be traced back to an old hunter, and your pet’s vision is still calibrated to detect scurrying prey – or a fast-moving toy. Motion is detected by the same rods that detect low light, and cats and dogs have considerably more rods than cones. When it comes to how both animals view the world, movement may be the single most essential component.

Dogs can sense even the smallest movement, such as a hand wave, from up to a half mile distant. Canines, on the other hand, frequently struggle to recognize stationary objects a few inches in front of their noses, which is why your dog may appear bewildered when you drop a treat right in front of him. Wiggle the treat a little and his attention will be drawn to it.

This happens because cats and dogs are naturally drawn to movement. Unless your pet is well-trained, movements in their peripheral vision may trigger a pursuit response, and both dogs and cats have excellent peripheral vision.

They also have a wider field of vision than humans. While we can see about 180 degrees in front of us, most cats can see nearly 200 degrees because their eyes protrude slightly outward, whereas ours are positioned further back in our sockets. Depending on the breed, dogs with eyes closer to the sides of their heads have a 240-degree field of vision.

Cats and performers not only have a wider field of vision than humans, but they also see things more quickly. Cats, dogs, and humans all perceive the world as a series of quick, static images. In a fraction of a second, the retina receives light and turns it into an image for the brain. For humans, this happens around 60 times each second. In dogs, it happens between 70 and 80 times every second (this measure of snapshots-per-second is called the flicker fusion frequency). As a result, when you throw a ball, your dog takes fractionally less time than you to see where it’s going, which explains why dogs rarely miss a catch.

Most dogs are uninterested in television because of their incredible sense of movement, even when a dog food commercial is on. TV shows, videos, and movies are made up of a sequence of still pictures that flash across the screen at a slightly quicker rate than our flicker fusion rate, providing the illusion of fluid motion. Dogs notice the gaps because they have a faster flicker fusion rate, so TV seems to be a fast slideshow of static photos.

A Minor Mistake

Cats and dogs are excellent at detecting motion, but they are less skilled at identifying minute details. Dog eyesight is substantially less accurate and clear than human vision, and it has been compared to that of a middle-aged bifocal wearer without glasses. This isn’t an issue for dogs because they primarily utilize smell to learn about their surroundings.

Cats, in particular, are prone to being little nearsighted. Human eyesight can be quite good up to 100 or 200 feet away, whereas cat vision is best between 6 and 18 feet and becomes blurry after around 20 feet. Because their eyes lack the muscles that modify the curvature of the lenses, which varies the distance at which the eye focuses, cats have difficulties seeing anything closer than 6 inches away or more than 20 feet away.

Various viewpoints on the same planet

So, what do cats take heed of? What do dogs take note of? Because cats and dogs have less red cones than humans, they experience the world in blue, gray, and yellow tones. Consider your pet’s point of view the next time you look at him.
