Will a cat protect its owner when it sees a ghost, and can a cat really see a ghost

No.

Because there are no ghosts in the world itself, cats will not see ghosts, nor will they protect their owners.

Cats, belonging to the feline family.

Fungi can be transmitted to the human body** and are the most widespread pets in households worldwide. The ancestors of domestic cats are presumed to be ancient Egypt.

The desert cat, the Persian cat of Persia.

It has been domesticated by humans for 3,500 years. Cats have fatty pads on the soles of their toes so that they don't make noise when they walk, and they don't startle mice when hunting. The claws are in a constricted state when marching, preventing them from being blunted, and they will stick out when catching rats and climbing.

This is more subtle, but meeting a black cat at night is more terrifying than meeting a dog!!

Pretty much, due to the different physiological structures, animals or insects see the world and hear different sounds than us, for example, we can't hear sounds higher than 200hz frequency, but some creatures can, so ghosts, other dimensional subspace substances, should be seen with special imaging capabilities, I dare not say that cats can definitely see it, but maybe.

I don't know if cats can see it, but I heard from the old man that children can see it, my brother is two years old, and he is often suspicious, and I am more afraid.

Will anyone know the answer to this?

Ghosts don't dare to come in if they have cats at home, because cats' eyes can see some things that people can't see, and cats are particularly alert, so ghosts feel that it's not safe to come in, too nervous, and if you have cats, it's particularly safe at home.

Cats can see ghosts, this is a folk saying, or let's take a look at the scientific explanation:

The lens and cornea of cat's eyes are relatively large, and the photoreceptor cell layer is 6 to 8 times that of human eyes, which means that cats can see many things that humans can't see, especially at night, and cats' ability to see things is much stronger than that of humans.

Moreover, cats are extremely sensitive to moving objects, and the limit is seconds. That is to say, humans are dazzled when they look at a thing, and cats are small insects that can lock and move in such complex things.

The pupils of cats are very large, and the ability of the pupils to contract the sphincter is also super strong. The size of this pupil is adjusted according to different rays of light. In the morning, the pupil is jujube kernel-shaped, and at noon, the sun's rays are strong, and the pupil is a thread.

At night, when it is dark, the pupil can be as large as a full moon.

The lens and cornea of the cat's eye are relatively large, and the photosensitive layer is 6 to 8 times that of the human eye, which means that cats can see a lot of things they can't see, especially at night, and their ability to see things is much stronger than that of humans.

And cats are extremely sensitive to moving objects, the limit is seconds. In other words, humans are dazzled by anything, but cats can lock on to moving bugs in such a complex thing.

In the morning, the pupils are jujube-shaped. At noon, the sun is strong and the pupil is a thread. When the night is dark, the pupils can be as large as a full moon.

<> cats are also spiritual animals, and as long as the owner treats it well, the cat will have feelings for the owner. When a cat sees a ghost, it will warn the owner through some abnormal behavior, which is a way for the cat to protect its owner. But in fact, cats don't see ghosts.
