Cat can see all colors

How do cats see at night?

The sensory cells in the retina, the so-called rods, are responsible for the perception of brightness. Light entering through the pupil excites these rods. The more aroused, the stronger the perception of brightness in the brain.

But why do cats see so much better in the dark than we humans do? For one thing, cats' eyes have significantly more rods than those of their owners. So you specialize in the light-dark view.

On the other hand, cat eyes have another structure that supports night vision. We are talking about the tapetum lucidum (Latin for shining carpet). This is a mostly crescent-shaped structure that is located in the choroid of the eye. Not only cats but also dogs and cattle have it.

The tapetum lucidum consists of many small, crystal-like shapes that reflect the incident light like a mirror. This in turn increases the excitement of the chopsticks. Cats can therefore see something even when there is hardly any light.

Pay attention to the following on the next night walk: If the moonlight or the light of a lamp falls right into the eyes of a cat, you can perceive this structure as a yellowish or blue-green glowing layer.

When it is completely dark, however, even cat eyes are overwhelmed and in this case fur noses have to orientate themselves differently. But they also have other, well-developed senses.
