Some cats (such as China Linqing Lion Cat and angola cat) have genetic defects, beautiful blue eyes and deaf ears. Therefore, people crossed this cat with a yellow-eyed white cat to breed a Yuanyang-eyed cat, a white long-haired cat with yellow eyes and blue eyes, but one side of the blue eyes may also have deafness defects.
In fact, not only cats, but also the characteristics of Yuanyang eyes appear in dogs.
Pigeons also have "Yuanyang eyes", which is a kind of eye sand. Pigeons with different sand eyes will have lovers' eyes. One side is chicken yellow, the other side is peach blossom; Or a bull's-eye on one side and chicken yellow or peach blossom on the other. Pigeon eyes cannot be inherited, but competition and reproduction are not affected. The eyes of purebred cats are the same color, which is generally considered to be caused by hybrids. Most of these cats (Linqing cats in China or Ankara cats in Turkey) have genetic defects, beautiful blue eyes and deaf ears. Therefore, people crossed this yellow-eyed white cat and bred it into Yuanyang eye, a white long-haired cat with yellow eyes and blue eyes, without the defect of deafness.
The blink of an eye of a Persian cat depends on its coat color. It is generally believed that Persian cats have blue, green, copper, gold and amber eyes, which are strange in color and different in color (that is, Yuanyang eyes). Persian cats with Yuanyang eyes often have white fur. Cats with green, amber and golden eyes generally belong to the silver-gray coat color system. The purer the color of all kinds of eyes, the darker the better, and the color of eyes is even.
