We've always been taught that cats and dogs only see the world in black and white, but that's not entirely true
How do cats and dogs see the world?
You sure wish you could know what's going on in the heads of cats and dogs, especially if they're your pets. This will give you a much better view of the world, or at least make you a better animal owner. Here we want to reveal some of the secrets of animals and give you some advice about raising them.
How do dogs and cats see humans?
Take a quick photo of your dog or cat, and you'll see their eyes light up in a way that's both adorable and terrifying at the same time. This strange light comes from a layer in the eyes of these animals called the tapetum, which reflects light, helping these animals see small amounts of light much more efficiently than our human eyes. In fact, our pets sense the world in a very different way than we do.
As children, we learned that dogs and cats suffer from “color blindness” or see the world only in “black and white,” but this is not entirely true. “These animals cannot see all the colors that we see,” says Kathryn Haupt, a professor at Cornell College of Veterinary Medicine. Apparently, she sees the world in shades of blue and yellow.

From a physiological point of view, distinctive vision is due to the presence of types of photoreceptors in the eye itself. “Because dogs and cats are predators, they don't have to differentiate between similar shades,” Haupt explains. As protozoans, we have to know if that persimmon is ripe or not. “We are better at distinguishing colors because we need to choose the right food.” In other words, for cats and dogs, a gray rabbit is just as delicious as a brown rabbit.
Do dogs and cats see the same
When it comes to clarity of vision, humans have an advantage over dogs and cats. If the dog is able to distinguish an object at a distance of approximately 6 meters; A person can distinguish it at a distance of 18 meters. This difference increases in the case of cats, as what a cat can see at a distance of 6 meters, humans can see at a distance of 30 or 60 meters. Our pets have not evolved to process accurate images of the world around them.
However, these animals have an advantage when it comes to motion perception, a skill that has evolved to help them catch their fast-moving prey. While most dogs and cats struggle to locate stationary objects close to them, they can track movements from about half a kilometer away, even if the movement is relatively subtle.
How do cats and dogs see each other
Dogs and cats can also see many things at the same time more efficiently than humans. While our field of vision is about 180 degrees, the eyes of cats and dogs can protrude slightly outward, expanding their field of peripheral vision to exceed 200 degrees. Even if they cannot identify what the moving object is, they will know that something is moving nonetheless.
The field of view may vary from one type of dog to another. For example, the bulldog has a relatively small snout compared to other species, which helps it when observing nearby objects and gives it a wider field of vision.
How cats and dogs see the world
One common and correct idea is that dogs and cats see very well in the dark, in part because the mat layer reflects light onto its receptors in their eyes. This is because have a larger number of rods than ours - 6 to 8 times that of cats. , which means that they are able to form useful images using smaller amounts of light.
That's not all. When you take into consideration all the advantages and disadvantages related to the vision of dogs and cats, you should not ignore the way this sense interacts with the other senses as well.

Cats can sense the ultrasonic frequencies that their prey normally emits, allowing them to continue their pursuit for a longer period of time, even if the prey is out of their field of vision. They can also use their sense of smell as a primary way to identify people. If you are gone for a while, the cat may not recognize you until it smells you well. If you change your shampoo during your absence, you will get into trouble.”
Dogs also have a keen sense of smell. Like cats and other types of animals, they possess an organ called the vomeronasal organ as part of their olfactory systems that specialize in their olfactory needs. This organ helps animals communicate through smells and strengthens their sense of smell. Depending on the species, dogs' sense of smell can be 1,000-10,000 times greater than that of humans.
Cats see 9 dimensions
With these preferences, dogs and cats don't need to rely on their vision to navigate the world. However, their visual disadvantages may pose some problems for humans who want to train their animals to new tricks. This becomes a problem when training guide dogs for the blind. That is why she must be taught that a dark yellow light means she must stop.” In an ideal world, traffic signals should have some sort of scent to help dogs determine when it's time to walk.
