“Enchanting Kitty: A Feline with Remarkably Heterochromatic Eyes”

Let me introduce you to Niu Nai, a delightful ebony cat with an extraordinary genetic feature – two distinctively coloured eyes! The cat’s parent has shared cute videos of Niu Nai’s captivating stare on social media, drawing attention to the unique condition known as heterochromia iridis. This unusual phenomenon is typically observed in white cats owing to low melanin levels, and it is hereditary. Interestingly, Niu Nai’s moniker means “milk” in Mandarin, which only adds to her already adorable persona!

The owner of the cat, which is named Niu Nai, meaning milk in mandarin, shared videos of the moggy to social media showing its colourful eyes

A person who goes by the name of Niu Nai on social media has been sharing videos of their cat with the same name, known for its strikingly colorful eyes. The color of our skin and eyes are determined by melanin pigment. When kittens are born, they typically have blue eyes, but as they grow older, melanin moves to their irises, causing a shift in eye color. By 12 weeks old, their eyes will have settled into a permanent color, which can range from blue to green, brown, or yellow depending on the amount of melanin present. The video showcases Niu Nai’s eyes, their size, shape, and how they change under different lighting conditions.

Known as heterochromia iridis, or odd-eyed, the condition is passed down through genes and usually affects white cats as it's connected to low melanin levels

Heterochromia iridis, which is also known as odd-eyed, is a genetic condition that is commonly found in white cats due to their low levels of melanin. This means that one eye will have a different color than the other. As the pupils dilate, the amount of visible color reduces. Several breeds, including Japanese Bobtails, Khao Manees, Oriental Shorthairs, Persians, Sphynxes, Turkish Angoras, and Turkish Vans, exhibit this characteristic. A delightful video shows a cat with heterochromia iridis enjoying a warm bath. Additionally, some cat owners’ Instagram posts may feature a blue eye that appears red due to the layer of melanin over it that removes certain colors of light, creating a red-eye phenomenon in pictures.

As its pupils dilate the amount of colour that can be seen lessens. And in one adorable clip the cat is seen enjoying a warm bath

As the cat’s pupils expand, its vibrant world begins to blur and fade away. A delightful video showcases the adorable feline luxuriating in a warm and soothing bath.
