Why do cats naturally like to eat fish?

What cat doesn't like the smell of fish is a comment on the eating habits of cats. In other words, cats love mice and fish. It's interesting to say that if the cat can't be fooled by the fish flattered by its owner for a long time, it can go to the river at night to "do it by itself" and fish live fish from the water to satisfy its appetite!

So, why do cats especially like to eat fish and mice?

Scientists have studied and analyzed this problem. It turns out that cats need taurine, a substance that can improve night vision, to move at night. If cats do not supplement this substance for a long time, their night vision ability will be reduced and they will not be able to perform their duties. But fish and mice contain a lot of taurine, so cats must take taurine from them to supplement their nutrition. So cats love fish and mice.
