Hello, this is my close up selfie, so that you can see that my eye colors are heterochromia. My right eye is blue and the left eye is amber. My twin also shares this quality.
Japanese bobtail, Turkish van, and Turkish angora are the 3 different cat breeds that are most likely to have different color eyes.
Although, quite similar, to the Turkish vans, we are both natural breeds that originated from Turkey. One difference is that Turkish van's like to play and swim in water.
I can attest that my human friend realized I am definitely a Turkish angora when I accidentally fell into the bath tub.
