Cats are known for their mesmerizing eyes, which often seem mysterious and otherworldly. But beyond their captivating beauty, cat eyes are packed with fascinating features and abilities that many people don’t know about. Here are 10 surprising facts about your feline friend’s eyes.
Cats Have a Wider Field of Vision Than Humans
While humans have a field of vision of about 180 degrees, cats can see roughly 200 degrees. This wider range allows them to detect movement from the sides more effectively, making them excellent hunters. Their peripheral vision is a key advantage when stalking prey or playing with toys.
Their Night Vision Is Remarkable
Cats are crepuscular, meaning they are most active during dawn and dusk. To aid their twilight adventures, their eyes are equipped with a layer of tissue called the tapetum lucidum, which reflects light back through the retina. This gives them superior night vision and creates the glowing effect you see when light hits their eyes in the dark.
Cats Have Vertical-Slit Pupils for Precision
Unlike humans, who have round pupils, cats have vertical-slit pupils. This shape allows them to adjust their pupil size quickly and efficiently, providing greater control over the amount of light entering the eye. This feature helps them accurately judge distances when pouncing on prey.
They See in Limited Colors
While cats can see color, their spectrum is much more limited than that of humans. They primarily perceive shades of blue, gray, and green, but reds and oranges appear muted or grayish. Their vision is more adapted for detecting movement and contrast rather than distinguishing between a variety of colors.
Cats Can Develop Heterochromia
Some cats have two different-colored eyes—a condition called heterochromia. This trait is most common in certain breeds, such as the Turkish Van, Khao Manee, and odd-eyed white cats. It occurs due to a genetic variation that affects melanin distribution in the iris.
Their Eyes Can Reflect Their Mood
Cats use their eyes to communicate emotions. Slow blinking is a sign of trust and affection, while dilated pupils can indicate excitement, fear, or aggression. Narrowed pupils, on the other hand, may signal contentment or calmness. Observing their eyes is a great way to interpret their feelings.
Kittens Are Born with Blue Eyes
All kittens are born with blue eyes due to a lack of melanin in their irises. As they grow, the melanin develops, and their true eye color begins to emerge. By the time they are around 6 to 8 weeks old, their permanent eye color is usually set.
Cats Are Prone to Eye Conditions
Felines can suffer from a variety of eye-related issues, including conjunctivitis, cataracts, and glaucoma. Certain breeds, like Persians and Himalayans, are more prone to eye problems due to their facial structure. Regular vet check-ups can help catch and treat these conditions early.
Their Eyes Glow for a Reason
The eerie glow in a cat’s eyes at night is caused by the tapetum lucidum, which enhances their night vision by reflecting light. This also explains why their eyes sometimes appear bright green, gold, or red in flash photography.
Cats Have a Third Eyelid
Cats have an additional eyelid, known as the nictitating membrane, which moves diagonally across the eye. This translucent layer helps protect their eyes from dust and debris while keeping them moist. You may occasionally see it when your cat is drowsy or unwell.
