Cat's eyes are jade eyes. What happened?

The word "jade eye" is actually a relatively broad concept. It describes that the color of an animal's eyes is similar to that of jade or stone, which usually means that the eyes are rich in yellow-green pigments and particularly bright.

Cat's eyes are described as "jade eyes" mainly because there is a ring composed of yellow pigment and green pigment around its pupil. In a certain light, this ring will show a unique green tone, leaving a very deep and beautiful impression. Although not all cats have such eyes, this special appearance has brought a lot of appreciation and love to many people.
