Why is the cat's tail curved and called unicorn tail?

The unicorn's tail should have a joint on the cat's tail, so that the tail can be folded at right angles, just like Pikachu's lightning tail in the pet elf. I remember a cat friend in the cat nest once verified that her cat was a unicorn tail, and unicorn cats were liked by many people. There's nothing unlucky. That's nonsense.

Unicorn tail was caused by gene mutation in the process of cat inheritance, and then gradually stabilized and became a recognized genetic phenomenon without any harm. Give an example that the landlord can understand: everyone has a thumb. Some people can bend their thumbs to nearly 90 degrees, while others can't bend them at all. This is a recognized genetic phenomenon, without any harm. In either case, it has no effect on people, and it is all in the innate genes. This is the case with the unicorn tail. A cat with a unicorn tail in China legend is lucky.

In southern Fujian, many people like cats with unicorn tails, because in ancient times, it was said that this kind of cat had special magic power and mice would be afraid of him, so few mice would stay at home, and this kind of cat was good at catching mice, which was the most important thing.
