Kittens are born with their eyes closed and usually open them between 7 and 14 days of age. On average, the process starts at around one week old and takes a few days. The timing can depend on the kitten’s development, its breed and even how long the pregnancy lasted.
Many breeders notice that shorthaired kittens tend to open their eyes a little earlier than longhaired ones, but every litter is different.
At first, the eyes are just cloudy slits with pupils that don’t react much. A little later, they become tiny blue beads.
Why Kittens Are Born with Their Eyes Closed
Kittens are born blind, deaf and completely helpless, and there’s a good evolutionary reason for that. A cat’s pregnancy is relatively short, about 63–65 days. Cats are predators that need to hunt, and a long pregnancy would make it hard for a mother to catch food. So her kittens are born before they’re fully developed, and their eyes and ears keep developing after birth behind closed eyelids and ear canals.
The closed lids also protect the delicate developing eyes from light and dirt. Kittens open their eyes only when they’re ready to meet the light. The process is gradual and different for every kitten, and you shouldn’t try to speed it up: never try to pry a kitten’s eyes open.
At first, the eyes open just a little, like narrow slits. The eyes look cloudy and pale, and the pupils barely move. That’s because the kitten’s visual system can’t yet process what it sees properly.
Within a few days (it varies from kitten to kitten), the kittens’ eyes start to follow movement, and they learn to tell light from shadow. Their irises are still a cloudy blue. It’s best to keep the kittens in soft, dim light at this stage; bright sunlight can be uncomfortable for their sensitive eyes.
By about 2 weeks of age, all the kittens’ eyes should be fully open. Once kittens open their eyes, they start reacting to movement, become much more active and get interested in objects around them. Their ear canals open at around 5–8 days, and their hearing gets much sharper by the end of the second week, so they begin exploring the world with real curiosity.
The eyes keep developing for several more weeks until the kitten’s vision becomes truly sharp, which usually happens by about 8–10 weeks. At the same time, kittens’ eye color starts to change: from about 6–7 weeks, the blue fades to the adult color, which is usually set by about 3 months.
Does Breed Affect When Kittens Open Their Eyes?
The timing depends on how quickly a kitten develops, and some breeders report that their breeds tend to be early or late openers. For example, breeders of Sphynx, Cornish Rex and Siamese kittens often say their kittens open their eyes early, sometimes within the first week, while Persian, Scottish Fold, Maine Coon and Ragdoll kittens may open theirs closer to 10–14 days or even a little later. These are general observations rather than strict rules.
If a kitten’s eyes are still closed after about 2 weeks, or if you see swelling, bulging or discharge under the closed lids, contact your vet.
How to Care for a Kitten’s Eyes
Until a kitten’s vision is fully developed, protect it from bright, direct light. Keep the kittens in a quiet, dimly lit spot, without sudden flashes of light.
The mother cat keeps the nest clean, cleans up after her kittens and licks them. Usually that’s all the eye care kittens need. But young kittens’ eyes are vulnerable to infection, and sometimes a mother can’t keep them clean, so it’s important to check them every day.
Healthy eyes don’t need cleaning. If you see a little crust or discharge, gently wipe it away from the inner corner outward with a cotton pad or soft cloth dampened with warm water or sterile saline solution, using a fresh pad for each eye. Don’t use tea, herbal infusions, boric acid, antiseptics or any human eye drops without your vet’s advice, and never try to force the eyelids open.
If an infection develops, with pus building up in the eyes, crusts sealing the lids shut, watery eyes or swelling (sometimes visible as a bulge under eyelids that haven’t opened yet), take your kitten to the vet right away. Eye infections in newborn kittens can quickly damage the eyes. The vet will examine the kitten and may prescribe treatment, usually gentle cleaning plus antibiotic eye drops or ointment. Infections from viruses such as feline herpesvirus are common in young kittens, so early treatment really matters.
Don’t experiment with your kitten’s health or try to treat it yourself. Follow the treatment plan your vet prescribes.
