When we were young, we must have seen the cartoon “Cat and Mouse”. We all know that cat and mouse are always deadly enemies and cats have the skills to catch mice. But what I want to talk about today is not why cats like to catch mice, but why cats like to eat fish so much. To know, fish are aquatic animals, as a land animal cat why only like to eat fish?

Cats are known to have a pair of awkward big eyes, many people love it because of these eyes, and this pair of eyes is also an important reason why cats like to eat fish. Through the study found that cat is a nocturnal animal, it needs a bezoar acid substances to improve their night vision ability, the cat itself cannot give yourself bezoar acid, and on mice and fish is rich in such a material, so the cat will catch and eat rats and fish to supplement the body needs of bezoar acid. When cats are chronically deprived of the substance, their own night vision deteriorates until they become blind at night, which limits their ability to move at night.

So cats eat fish not only because they like it, but also because they need to supplement their bezoar acid by eating fish. There is also a legend story, said that before people out to sea fishing will bring a few cats catch mice on the ship, when the feed the cat food is not enough, people will feed the catch of fish to eat cats, fish for cat is a kind of both delicious and nutritious food, they are particularly fond of, slowly, the habit of the cats like to eat fish, it survived, And it has survived to the present day. Of course, this is just speculation, there is no scientific basis.

Cats are not all pure land animals, some cats can swim, generally speaking, the domestic cat can swim not much, but its close relatives ocelot can, and is the cat family in the swimming. So there may be some reason why cats like fish, as long as they keep eating it, they can keep their eyes glowing at night.
