Serenity is my odd-eyed cat -- aka "oddies" -- 2 different colored eyes. It occurs in mammals, including humans. Technically "heterochromium iridium."
Reminiscent of Japanese maneki-neko -- white cat. Also called Beckoning Cat, Fortune Cat, Lucky Cat, Money Cat, Welcoming Cat.
Thailand has a Royal Cat Park near Bangkok for 'Khao Manee' (White Jewel) cats.
Turkish Angora or Ankara, and Turkish Van cats are prized.
Japanese bobtail white cats may exhibit heterochromia.
