Although rats love to steal food, chew all kinds of furniture, and spread diseases such as plague, which is extremely hateful, from the perspective of the food chain, not only do rats have no mistakes, but they must be credited with their credit card no matter what. A note-they are free lunches for carnivores. Because there is almost no carnivore that does not eat mice. Mammals such as lynx, foxes, jackals, etc., birds such as owls, snakes such as pythons, golden snakes, etc., amphibians such as bullfrogs, etc., even the dogs guarding the house have been called "dogs that take care of mice and meddle in their own business" because of this. Then why do cats like to catch mice so much?
That's because for cats, mice are the most nutritious meal! Mice are not only rich in protein, but are also rich in a substance called taurine, which cats cannot synthesize by themselves, but are particularly important to cats. Because once there is a lack of taurine, the cat's vision will decline at night, and long-term lack will cause night blindness, making it impossible to move at night! Therefore, in order to have good vision at night, cats must catch mice often and eat them. Pet cats kept at home, because they cannot eat mice, should be appropriately supplemented with foods rich in taurine, such as sea fish, mammalian hearts and livers, etc.
Of course, the reason why cats developed the nature of eating mice was because there was so much food that they couldn't finish it. You see, there are so many natural enemies eating mice, and mice can still live forever. It is a miracle of nature!
