How cats see

How cats see

How cats see, is something you ask yourself when you see them snap suddenly for no clear reason. Without clear reason for us, but they probably see it very well. That's why I often ask myself, I don't know about you, “How do they see the cats?”.

The first difference, which catches the eye, concerns thebreadth of views that these felines have compared to us. They have a field of view of 200 degrees, we only have 180 degrees. This means that compared to us these animals see 10 degrees more on each side: in a nutshell, in degrees, we 20 degrees on each side, they 30. This already makes us understand better How cats see and what they see more compared to us.

How cats see in the dark

It is not an urban legend that cats see in the dark. It's not about super powers, but these animate at least see it six times better in dim light than humans, sometimes even 8 times better. This feature is linked to the shape of their pupil which, for those who have the eye of cats in mind, is clearly elliptical.

The size of the cornea also influences How cats see. If we then look at the retina, ours and that of cats, we discover that they have more rods than cones, therefore a more developed ability to see in dim light and during the night than we have more cones. We, on the other hand, rich in cones especially in the fovea area, can see the bright colors and the outlines much better even at high resolution.

How ghosts see cats

If we believe in ghosts, we can also ask ourselves How cats see these beings, in reality, however, these animals have a different vision of colors than us, without having however the visions of psychics. Until recently it looked like they had one dichromatic vision like dogs, or like those of us humans who have protanopia, a form of color blindness that means that only red and green are caught.

Today, however, studies are being carried out on how cats see and it is not excluded that they also take other colors, those tending to green.

Although generally considered a disability, in some situations the Color blindness can prove beneficial; a color blind hunter, for example, may be able to better distinguish prey camouflaged on a chaotic background. And this is precisely why the visual apparatus of our feline hunter friends is designed. This allows them to record very fast movements, very useful when to escape from their clutches are small animals that change direction very quickly.

How cats and people see

We have already seen some differences between how cats and people see, first of all regarding the night vision. There is also the different reaction that we and them have in capturing the movements. Once again, they win, seeing objects moving at 10 times faster than us.

How small cats see

When you have a kitten at home, you take care of it and follow it in the phase in which it is discovering every cm that it has around it, you also begin to think about how small cats see compared to adult ones. Help comes from the world of photography, with a project by Nickolay Lamm which compares how a cat and a man see looking in the same direction.

Not a fanciful operation, this artist enlisted the help of a team of expert animal vision scientists All Animal Eye Clinic, ofAnimal Eye Institute and the Penn Veterinary Center.
