If you want your cat's eyes to glow at night, you need to shine a strong light on his eyes.

Cat eyes do not shine at night, because the cat lacks taurine caused, usually pay attention to the cat to supplement taurine to promote the absorption of nutrients needed by cats.

In this case, when the cat's eyes do not glow at night, because at night, if he closes his eyes, the pupils of the eyes do not reflect light, so his eyes will not shine at this time. His light is actually reflected light.

The cat's eyes don't glow, it just has a polarized light. If there are other light sources around him, his eyes will reflect them.

The cat's eyes don't shine at night, that's because there is no light shining on him, in fact, it should be reflective, you don't have light, how can it be reflective?

Cats, the reason why the eyes do not shine at night is mainly that there is no light source, if there is a light source elsewhere, after the refraction of the light source, you will find that the eyes of the kitten are very bright at night.

Cats, what is the reason why their eyes do not glow at night? It may be that the cat's eyes are tired at night, and in this case they do not glow, and it is normal to reflect light, so please don't worry.

What is the reason why cats' eyes don't glow at night, cat's eyes seem to glow when they have light.

At night, the cat's eyes are not glowing, but reflective. Domestic cats and wild cats are the same in the structure of the eyeballs, so the eyes of domestic cats will also reflect light, but the angle and environment you are in are different, so it is considered that domestic cat eyes are not reflective.

Cats are known to have large eyes and a wide field of view, 285 degrees (210 degrees for humans), especially at night, when there is little light, cats can also catch mice, cockroaches or other small animals.

There's something in the cat's eye called a bright blanket.

Someone has experimented with putting a cat in a completely dark room where there is not a glimmer of light, and the cat also sees nothing. This test shows that cats' eyes also need light at night, but the light requirements are very low.

After doing research on the structure of the cat's eyes, it was found that the cat has a mirror-like structure in front of the retina. The faint light rays enter the retina and hit this "mirror", where they are reflected back onto the retina. This structure is like an amplifier that allows light to pass through and also increases the intensity of light.

People call this structure the "bright blanket".

The glow you see is the reflection.

When people take pictures of cats, if the angle is right, they can see that the cat's eyes are glowing, which is actually the reflection produced by the bright blanket.

It is said that the eyes of wild cats are glowing because the angle of the camera just captures the reflection in the eyes of wild cats, and when the domestic cat is not there, you don't find the right angle, and you will find it if you look at it more.

Kitten eyes do not shine at night, because the cat lacks taurine caused, usually pay attention to the cat to supplement taurine to promote the absorption of nutrients needed by the cat, the light of the cat's eyes is not the light of the cat's eyes themselves. If the cat's eyes do not shine at night, it may be that the cat lacks taurine, which is very important for the cat's vision. Once the cat is deficient in taurine, the cat's vision will gradually decline, the vision will become blurry, and the retinal membrane will also be damaged.

Although the cat's eyes do not glow and only reflect, it is also necessary to pay attention to the cat's eyes. You can choose a cat-specific posture cavity cat taurine supplement to promote the cat's absorption of taurine.

The structure of the eyeballs of felines and canines is more special. When the light passes through the retina and reaches the iris at the back of the eyeball, it is reflected back to the retina for imaging, which is why cats and dogs can also hunt at night with the help of shimmer light. The light reflected back from the iris still passes through the retina, which is why you can see the eyes of cats and dogs glowing in low light.

The cat's eyes are special, and when the light is a little stronger, its eyes will be in a line; When the light is low, its pupils will dilate; In the dark, the cat's eyes glow, and whenever these eyes shine, it always makes people feel frightened.

In fact, the cat's eyes do not emit light by themselves, but there is a reflector-like substance on the retina behind its eyeball, which can reflect the collected light energy. So when you see a cat at night, your eyes are bright. This pupil of a cat is very elastic and its ability to contract is also very strong.

Therefore, the cat's vision is very keen, and it should be 6 times stronger than the human vision. This keen vision and wide perspective make it see a much larger range than others. This kind of extremely strong vision also constitutes a necessary condition for its survival, which starts from the role of the pupil, which is located before the lens, and controls the intensity of light entering the lens, which changes with the intensity of the light in the outer line.

After the pupils of the cat become larger at night, try to receive more shimmer light, but because of the convergence of the lens and the ciliary body, that is, the convex lens, the light converges in a small range, precisely because the pupil is large and the photoreceptor cells of people in the dark night are columnar cells, and the sensitivity is enhanced, so you can see that it is bright!

There are many special crystal points at the bottom of the wolf's eyes, and these crystal points have a strong ability to reflect light, which can gather the weakly scattered light around them, aggregate them into bundles, and reflect them intensively, as if the wolf's eyes are shining.

It is a common physiological phenomenon in wild animals. There are many special crystals at the bottom of many animals' eyes, these crystals have a strong ability to reflect light, can gather the weakly scattered light around, aggregate into a bundle, and reflect it intensively, animals with such glasses generally have a strong ability to be nocturnal, they can distinguish objects with tiny light, and from the outside world it seems that their eyes are glowing. Most of the people with these glasses are nocturnal animals, including wolves, cats, tigers, etc.
