Cat eyes: Basic anatomy and functions

Apart from being beautiful, feline’s eyes are a unique and special creation of mother nature and have multiple functions than some other animals.They are always large compared to the head because it is necessary to be large as part of an agile predator.Humans have specialized areas in the retina to see specific specialized things while cats do not have limitation for specific things so they can see all.The images and light entered through the lens and appear on retina upside down but the nerves make our world ok again to see.Can a kitty see in total darkness? No, they cannot see in absolute darkness but only one/six quantity of faint light can make them see very well in darkness.The retina of nocturnal animals can make special glow in dark effect because of the reflective layer called Tapetum Lucidum which is behind the retina.In dark, cat’s pupil is fully wide enough to let the very faint light enter through the lens so light bounce back as glow in dark reflection by Tapetum Lucidum helps the animals to see in the dark for searching prey.Feline has a nictating membrane called the third eyelid which restores the moisture and protects from outer harm.This third eyelid partially closed condition in sick fur baby signs for taking an emergency to the vet.Unlike dogs, kitties are not color blind and they see the all the colors which we do.But fewer cones which are less concentrated than human eyes do not let them see all the color in good quality as they cannot distinguish green and red, even though they can see them.

Types of cat eyes and colors

Typically there are three types shapes by breed.They are Almond-shape which is normally found in Persian and Exotic short hair, Round- shape which is in Bengal and Scottish fold etc and oval- shape which is in Maine Coons and Ragdoll etc but oval and round shape can be seen in some other breeds too.3 main eye colors are documented in cats which effect on individual body function of feline.Blue eyes- Normally all kittens are blue eyes by birth but when they grow up, the color changes along with better vision.In 3 months of age, original color appears instead of blue. Siamese Tabby family and cross breeds which carry Siamese gene remain blue eyes until adulthood as a personal signature of that trait. Blue-eyed furry babies are deaf by gene but other breed kittens may be deaf for few months until the color changes blue to the original one. Rainbow color is the result of the pigment cells ( Melanocytes) quantity in eyes.The less amount of pigment cells create green color while gold and orange were formed by the vast amount of Melanocytes. In uncommon albinism, there will be no color to reflect without Melanocytes instead pink for capillaries inside.Beautiful white furry fellas with one green and one blue eye are kind of divine in look but it is called odd eye case.Some solid white cats have Heterochromia which is unmatched in eye colors.One side will be blue but another side may be Green or Orange. Heterochromia cats are one-sided deaf because of blue side.

Common eye diseases and symptoms

Not only humans, felines have important eye problems that should not be ignored.The most common diseases and their sings are shown in this article.If you ever notice any of those symptoms, immediately take your furry fella to the vet’s clinic for professional medical care.Those disorders are generally found in critical parts such as the cornea, pupil, Iris, Lens, retina and optic nerve.

Infection (Conjunctivitis)

This is also called pink eyes because of the red, swollen and discharge symptom due to the inflammation of outer and inner clear membrane layers of the eyelid.This can be caused by chemical irritations, allergies, fungus, bacteria, and virus.Instead of home treating, taking to vet is safer and will not go to the severe stage.

Corneal ulcers ( Ulcerative Keratitis )

This is open sore damages on the clear surface of the eye called cornea where light enters into the lens.The affected cornea shows redness, pain, cloudy, squinting and discharge signs.The corneal ulcer is typically found in outdoor kitties.Urgent treatment is necessary as soon as the disorder was found out or the severe case will lead the feline into permanent blindness if not treated in time.

Retinal Damage

Mostly found in cats with diabetes or kidney disease and older ones.The retina is the most innermost layer that accepts light and images so.The damages to the retina may cause permanent blindness.Very high blood pressure for hyperthyroidism, diabetes and kidney problems.So older and sweet tooth furry friends should take regular medical checkup for this.

There are some more diseases like Uveitis, Glaucoma, Cataracts, Exophthalmos, Enophthalmos etc.The main point is the earlier they are treated, the less chance of losing sight forever.Feline discharge normally every day too, so it is the duty of owners to clean discharge with soft cotton cloth or ball wet with warm water, check and notice any abnormal symptoms in eyes like redness, over tearing, rubbing with paws constantly, swollen parts etc.Better is to consult with the vet and take proper medical treatment as eyes are very important body parts to take care of.



  1. Thank you! I am writing a book about cats, in Spanish, to help an animal shelter where I live, in Ecuador, titled “How to Live with a Cat.” I am gathering information all over the Internet, about different topics related to the life of cats and adding them to my experiences with them.
    This has been of great help and I will translate into Spanish part of it, to use it in the book. The profit from the book will be 100% for the shelter.
    We rescue animals from the streets and make them in good conditions to be adopted. There is a veterinarian who takes care of the animal, neuter or spays them. The animals are bathed with anti fleas, desparasited, have the necessary vaccines and they are well fed. The kittens are trained for the litter box so when they are adopted they already have good manners.
    Every time a kitten is adopted we give the person a lot of advice but you would be surprised how many times the kitten dies in the first weeks at its new home because of accidents or something that the owners do wrong. Kittens are more fragile than people think.
    So, I decided to write this book which is like a manual that instructs the person what to do and what not to do, with the kitten. What the kitten can´t eat and what are the risks.
    Keep the good work on your blog.
    Kind regards
