‘Two-Faced’ Cat: The Most Rare and Beautiful Feline You’ve Ever Laid Eyes On!

This rare feline, known as a Chimera, has an exotic and unique characteristic — each half of her face is a completely different color, including her eyes.

Quimera the cat is like a character out of a comic: one part Catwoman, two parts Two-Face.

This exotic kitty with two different colored eyes and a furry face similarly split between two different colors belongs to a rare, V.I.P. group of pussycats who may (or may not…) be chimeras.

According to geneticists, a true chimera is quite the anomaly. As Columbia University professor of Genetics and Development Virginia Papaioannou explained, “A chimera … is a composite individual that was made up of cells from at least two different original embryos. If they fuse together early enough, they will become a single organism whose genetic input is from two completely different individuals. In a mosaic, there’s only one individual and it just happens to have different genetic components active in its cells. A chimera would be a much more unusual and unlikely event.”

Papaioannou believes that cats like Quimera, and her similarly stunning predecessor, are merely striking examples of calico cats.

“It’s a fairly straightforward example of X-inactivation mosaicism, with the addition of a white spotting gene. All female mammals have two X-chromosomes,” explained the professor. “In a cat, one gene for fur color is located on the X chromosome. And in any female, expression of all the genes that are on the X chromosome will be ‘mosaic’ — that is, half of them will express one version of the gene (e.g., black fur) and half will express the other version of the gene (e.g., orange fur). The inactivation is random. Here we are talking about the orange/black mosaicism, which is highly visible, but the same pattern will hold true for other genes on the X that have two different versions — or alleles.”

Okay, smarty. Then what’s the explanation behind her different colored eyes?

“It must be the white spotting gene that’s affecting her eyes, because the blue eye has a lack of melanin. This cat has white spots on the chest … the white spotting gene, the piebald gene, is probably affecting the two eyes differently. One has a sort of normal color and one is blue, which is basically a lack of pigment.”

Wow, that’s a lot of science to explain such an adorable creature like Quimera, who, for the record, probably has no idea how unusual she is. But her fans are fully aware: This gorgeous cat’s fan base is growing.

Still, you won’t catch Quimera with a chip on her furry shoulder: In all other ways, she’s a normal feline who loves to snuggle up with her human, hide under bed sheets, and paw around the computer.
