Cat's eyes, one of the aspects that most strikes the first encounter with these cats. They are mysterious, insightful, profound and inscrutable. They immediately make us understand that we are dealing with an intelligent animal that has no intention of being fooled, that perhaps wants to cheat us, certainly wants to go about its business, when it likes and if it wants. Thecat's eyes they are also anatomically special, not only from the point of view of the gaze, so much so that they see even in the dark.

Cat's eyes: anatomy

There are three concentric tissue membranes inside the cat's eyes. The external one is fibrous and is composed of the white sclera and the cornea. Then in the middle there is the vascular, thicker, composed of the choroid, ciliary body and iris, finally inside there is the nerve membrane.

To regulate the amount of light received by cats eyes there is the pupil, placed in the center of the iris, while to transmit images to the brain there is the retina which contains millions of receptors. Through this part of the eye, also through the optic nerve, it is possible to encode the light energy into electrical signals and get them to the brain which can convert them into images.

For the sake of completeness, it must be said that looking at the cat's eyes there are also the conjunctiva, containing the blood vessels, above the white part, and the lacrimal gland which can only humidify.

Cat's eyes: characteristics

Once the cat's eyes, we can observe them in their entirety by looking at the most significant characteristics starting from position and size. Of the head, they occupy the central and upper part, they do not depend much on the breed of the cat although there are exceptions. The Burmese, for example, has more protruding eyes than the average and even the Persian if you look closely at him. Other small differences can be seen in the opening of the eyelids.

Cat eyes: colors

Of the color of cat's eyes they have already talked about it together with the fur, but not yet about the colors that the animal sees. And it is by no means a trivial topic, especially if you think that the cat is above all a predator, so all its senses are developed to be able to capture prey, so first take a quick look at it.

It starts from the retina to notice what makes the cat's eyes special, because there are more in it rods which cones, the former are responsible for black and white, i cones of the conversion of light into colors. This explains why these felines are not very inclined to distinguish colors and this is not particularly important for their purposes.

Much better to have one instead good eyesight in times when there is little light: at sunrise and sunset, above all, time for "snack" and "breakfast", that is hunting. In these hours of dim light the cat's eyes they are able to capture an enormous amount of light compared to us thanks to the pupil that dilates up to three times more than the human one. Nothing escapes the cat even in semi-shade.

Veiled cat eyes

If we notice the veiled cat's eyes, it can be conjunctivitis, a rather frequent problem and which, if treated immediately, has no serious consequences. This disease can have an infectious or allergic origin, it manifests itself by making the cat's eyes veiled at times closed or swollen seeds. It can also be accompanied by mucus on the eyelids and itchy sensations. Unfortunately, conjunctivitis is also one of the symptoms in the case of poisoning.

Cat's eyes: night glows

Another mystery related to cat's eyes, in addition to the sight in the dark, is that of their nocturnal glow. Anyone who hosts a feline at home knows what "a look into the dark" means, sometimes staring at you while you want to sleep and you can't.

The fluorescence of the cat's eyes is not voluntary, it is due to the tapetum lucidum placed behind the retina. Like a mirror, it reflects light onto the sensors in the retina and makes your eyes shine they are just hit by even the smallest amount of light. A feeling of searching gaze that we can well experience with this Plush with glitter eyes 24 cm high, bedside table.
