There is nothing taboo about cats with different eyes. The scientific name of heterocoria is heterochromia iris syndrome, which can be divided into congenital and acquired forms. This symptom mainly manifests the difference in the color of the iris of the two pupils. The reason for the difference is that the color presentation is different due to different pigment deposition of the iris. It’s just that acquired heterochromia of the iris requires special attention. Heterochromia of the iris in middle-aged and elderly people is mostly caused by iris lesions. In this case, the cat needs to be taken to the hospital for treatment. There are no other taboos.
