Internet Can't Get Over 'The Most Beautiful Cat' and Her Striking Eyes

A video of a cat with incredibly striking eyes has gone viral on TikTok.

The clip was posted two days ago from the TikTok account Fiona The Cat (@fionathechonk) and had 6.6 million views at the time of writing.

The footage shows various close-up shots of a cat with piercing emerald green eyes staring at the camera.

A caption shared with the post reads: "She's genuinely the most photogenic cat in the world."

Cat eye color varies depending on the breed, ranging from blue, green and yellow to orange and brown, according to an August 2015 PetMD article.

Dr. Gaylord Brown, the veterinarian at D.E.L.T.A. Rescue, an animal sanctuary based in California, said in the article: "All kittens are born with blue eyes and at about 6 weeks of age they begin to develop their adult color" and "feral cats typically have hazel colored eyes."

Some cats may even have one blue eye, while their other eye is another color, which is a benign condition known as heterochromia, the article said.

So what gives cat eyes that unique glow at night?

Dr. DJ Haeussler, a board-certified veterinary ophthalmologist at The Animal Eye Institute in Ohio, explained in the PetMD article that feline eyes glow "when light is shined at them due to a reflective structure that is part of their retina known as the tapetum lucidum."

Most animals that are active at night have this special, additional layer (the tapetum) underneath the retina, an article by VCA, one of North America's largest animal hospital chains, notes. "This reflective structure acts like a mirror, and reflects light back through your pet's retina to enhance night vision," the article explained.

The eyes of cats glow differently depending on the breed. Most feline eyes glow bright green, while a Siamese cat's eyes glow more yellow. "This variation comes from the amount of zinc or riboflavin present in the pigment cells present within the tapetum lucidum," according to the PetMD article.

Several TikTok users swooned over the cat in the viral post and her colorful eyes.
