Cats eat mice, and cats are one of the natural enemies of mice, which is something we all know, but why do cats like to eat mice, simply because they are tied to the biological chain, or is mouse meat particularly in line with the cat's appetite?
In 2007, after a study by a German biology professor, he found that if cats do not prey on mice, their night vision ability will rapidly decline and become blind. We all know that the cat's eyes change, and his pupils can change shape several times in a day, sometimes large and round, sometimes squinting into a thin line, sometimes becoming a date-core shape.
Cats are active at night and often rest during the day. In order to adapt to this change in life habits, his eyes can change with the brightness of the light. Especially at night, the cat's large, round pupils still sparkle. If you shine a flashlight on it, the pupil immediately becomes a thin line. This special ability to regulate light and change rapidly is the same as many nocturnal animals.
But this bright eye of the cat, and half the function of the mouse. Originally, there was a substance called "taurine" that could improve mammals' nighttime vision ability, but cats could not synthesize it in their own bodies, and if they lacked it for a long time, they would become "blind" at night and eventually lose their ability to move at night. However, there is a substance in the mouse body that can synthesize "taurine" on its own, so the cat can only make up for the taurine in the body by constantly preying on mice, which is not enough to maintain and improve its night vision ability and survive normally.
Scientific research believes that cats in the city are currently in a vicious circle, because they rarely or almost do not eat mice, and the cat's ability to catch mice at night is greatly reduced, and this reduction is that they eat less rat meat. In this way, the mouse-catching ability of modern cats is naturally inferior to that of a generation. (In the future, I can only rely on the mouse trap [dog head])
