A cat with two different eye colors from China has become the internet’s latest favorite feline.
Niu Nai, whose name means “milk” in Mandarin, was born with heterochromia iridis, a genetic condition in which a pair of iris develops in different colors.
Heterochromia usually occurs among white cats, as the gene responsible for the color of their fur is the same as the gene which determines the color of their eyes, according to CatHealth.com.
The condition, which also occurs in humans, typically requires no treatment, unless it comes with an underlying health problem.
The fact that heterochromia is rare — and that Niu Nai is black — makes her a very special cat.
She lives with her human mom, Clare Zheng, who received her from a friend.
Niu Nai debuted to social media stardom on Weibo, where she has more than 16,000 fans.
The adorable feline can be seen staring right into the camera in most of her photos and videos.
In some photos, her blue, left eye registers as red, which apparently results from the movement of melanin and its interaction with light.
In March, Niu Nai branched out to Instagram, where she now has more than 38,000 followers.
With her beautiful eyes, round head and elegant coat of night, Niu Nai is definitely capturing the hearts of her many human admirers.
Fans are constantly sending much love her way:
