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 layer.it 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.

  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
    Marisa
