If you've just brought home a new kitten,  you might wonder when they'll reach certain developmental milestones. Today, our Glendale vets share some facts about when newborn kittens open their eyes and other information about their early days.

If you've never had the pleasure of raising kittens from a very young age, it may surprise you to learn how different they look from adult cats! A newborn kitten's eyes will be sealed tightly shut, and their ears are typically folded against their heads.

Since they're not yet able to walk or even stand, kittens are more or less helpless and dependent on receiving love and care from their mother or caretakers, so they can grow into happy, healthy adults. 

When do kittens start to see?

Typing the question, "When do newborn kittens open their eyes?" into your favorite search engine is sure to bring up a lot of information (and some adorable photos of young kittens). That said, just like people, kittens develop at different rates depending on several factors. However, most newborn kittens will start to open their eyes between the ages of 2–16 days. 

During this time, their vision will gradually improve, though the two eyes may not fully open at the same rate. Once they turn about two weeks old, both eyes are usually dilated. By three weeks old, many kittens can focus with both eyes. All newborn kittens have blue eyes; however, their eye color will change as they age, typically settling on the true color at about the eight-week mark. 

Caring For Your Newborn Kitten's Eyes 

You'll want to try to keep young kittens away from bright lights that may potentially hurt or even damage their developing eyes. If kittens aren't being well-cared for by their mother, or don't have a mother around, you'll need to ensure that the newborn kittens are clean and healthy. Use a damp, clean washcloth to wipe their faces clean. Most of all, never try to force a kitten's eyes to pen before the lids open naturally by themselves. Patience is essential. 

Eye Issues to Watch For & How to Treat Them 

Newborn kittens can develop a crust on their eyes that keeps their peepers from opening. This is a common issue that can be caused by bacterial or viral infection, which is just another reason to make sure that any bedding or areas your kitten shares with other kittens, cats or pets is clean and hygienic. This can prevent infections from recurring or spreading to littermates.

If a kitten develops this matted crust in their eyes, try cleaning their eyes gently with a cotton ball dampened with clean, warm water. Avoid soap entirely. If a kitten's eyes don't show improvement or worsen, call your vet right away to ensure they receive proper care. 

Your Kitten's Development

Similar to human babies, newborn kittens spend most of their time sleeping (around 22 hours every day), occasionally waking to be red and cared for. Kittens can sense warmth and rely on their sense of smell to move toward their mother's belly. A young kitten is dependent on its mother's milk and warmth to develop as they should. 

When do baby kittens open their eyes and start walking?

After your newborn kitten opens their eyes, they will gradually become more mobile and start to move around at about the same time their teeth emerge. They typically crawl by the time they around two weeks old and walk, jump, and play more steadily once they reach four weeks.

This is also when their propensity for mischief increases, since they are curious and adventurous. Beware they will often be eager to practice climbing, so be sure they have safe places to do so. As they mature into adult cats, kittens need less sleep. 

Keeping Your Kitten Warm

Because newborn kittens are unable to regulate their body heat, they usually gather in a pile near or on their mother. If your newborn kitten doesn't have littermates or a mother to keep their body temperature up, you'll need to help them stay warm by placing an item such as a heating disk or heating pad in their crate on low heat, underneath a blanket. 

Our vets also recommend building a nest out of blankets for your kitten to lay in and get comfortable. Check that the heating pad isn't too hot by touching it with your hands, and allow enough room in your kitten's crate or cage so that they can get away from the heating pad if they grow too warm. 

Continue to provide your kitten with a heating source until they are about six weeks old, because kittens will catch hypothermia if they get too cold. This is why their area should be kept at 85ºF or 29ºC. 

Providing Proper Nutrition

Of course, when caring for a newborn kitten without a mother you will need to feed them and provide them with proper nutrition. You will have to bottle feed your kitten a special kitten formula every 2-4 hours.

Every kitten is different. Your veterinarian will be able to inform you of the best formula to use, how much to feed them and how frequently you should be feeding your kitten.

For kittens to grow healthily, they will need to gain approximately ½ ounce (14 grams) per day or 4 ounces (113 grams) a week. Never give your cat cow milk and always make sure you are feeding them the same formula. And, for your kitty to digest food properly it will have to be kept warm.

Preventive Care for Your Kitten

No matter how old your kitten is, it's important to take them for their first veterinary appointment when appropriate. Your veterinarian will evaluate the health of your kitten as well as inform you of their dietary needs. This also provides you with the opportunity to ask any questions you may have regarding the care of your new family member.

Ensuring your kitten gets routine preventive care is vital, including wellness exams, routine vaccinations, and parasite prevention.

Regular wellness exams allow your vet to assess the overall health and well-being of your kitten including their dietary requirements. Your vet will also be able to detect any diseases early before they become severe when they are easier and more affordable to treat.

You also need to make sure your kitten gets all of their vaccinations and parasite prevention care on schedule. Your kitten should come in for their first round of shots when they are 6 to 8 weeks old, and you should have them spayed or neutered when they are 5 to 6 months old. This prevents any serious diseases or conditions from arising in the first place.
