We know that cats prey on mice is its nature. This is the common sense we taught us in books or in class. When there is a rat problem at home, we can also let the cat catch mice. Then we have I have never thought about why cats love to eat mice? Explain why cats eat mice from a scientific point of view!

 To prey on mice, cats must start with the cat's eyes. We usually observe cats and we will find them Its eyes are particularly divine, like a gem, and its eyes can also change the shape of the pupils with the replacement of day and night. In the dark night, its sparkling eyes add to the silent night. A touch of mystery. But in fact, the cat's vision during the day is much worse than that of humans. Due to the extraordinary ability of the cat's eyes to collect light, coupled with its high-performance hearing and amazing concentration, cats can also see things in the dark, even light. The darker it is, the clearer the cat can see. Cats have good vision in the dark because they have a well-developed cornea, and its curved lens is much larger than that of a human, so the cornea of the lens is positioned relatively close to the retina, in order to focus the light precisely , the curvature of the two has increased, and of course more light can be collected.

 In recent years, scientists have found that there is a kind of taurine in the cat's body. Taurine is a white or colorless oblique crystal, which is mainly distributed in the nerves, muscles and glands of animals. In the body, taurine is the chemical that improves the cat's night vision. Experiments have shown that the electroretinogram of cats lacking taurine shows extensive degeneration of rod and cone cells. Because cats themselves cannot synthesize taurine, they can only keep enough taurine in their bodies by preying on mice in large quantities, so as to maintain sharp vision at night and survive the fierce competition in nature, so it has always been Has the nature of preying on mice.

So, on the other hand, why do cats become good mouse catchers, just because they have good eyesight? Scientists have found that cats have a parasite in their bodies that can make mice behave abnormally. This parasite lives in the cat's intestines and is excreted through feces. The infected mice changed their behavior toward the cat, which then ate the mice, ending the parasite's life cycle. Scientists also say that the parasite is a very strange thing, and if they can increase their chances of completing their life cycle, they will undoubtedly do so. The parasites have a two-stage life cycle, which means they have at least two hosts, and mice are just one of their intermediary parasites. Cats are also one of their parasites, and this parasite can change the behavior of mice, causing them to be eaten by their main parasite, the cat.

This parasite in mice and cats It is harmful. Studies have shown that they will invade the nerves or the brain, and even they will have an impact on the human brain. Although cats can catch mice, it is very scary to eat mice raw. There are a lot of bacteria and viruses in mice. , a little carelessness can lead to infection. Therefore, usually, for our pet cats, it is better to keep them away from mice.
