Kitten Age Chart: How to tell how old a kitten Is

Watching a young kitten grow is an amazing thing to see, but you may be wondering about how to track their age and development during this crucial first year of life. Today, our Diamond Bar vets share some information about how to tell how old a kitten is, and advice about how to care for your new feline friend.

Raising a Kitten

Kittens are adorable and lovable household pets, however, they have very specific and ever changing needs that you have to take care of. If something goes wrong or is missed, it can greatly impact the kitten's overall health and longevity. Here we talk about how you can care for your new furry friend during their kitten years.

Under 1 Week Old

This is a crucial stage; kittens are extremely vulnerable in their first week of life. They can not hear or see. They are born with their eyes closed and they stay closed for the first week. A kitten's ears are folded closed so they can’t hear. While the kitten is this age there should still be an umbilical cord attached to the kitten.

Do not attempt to remove it as it will fall off when it’s ready. At this age, kittens need to be kept warm and a heat source should be provided to keep their environment between 85 to 90 degrees. Kittens are recommended to be fed every two hours. Momma cat normally will take care of thi,s but if the mother is not available it falls to the human caretaker.

We recommend speaking to a qualified veterinarian to go over feeding regimes and dietary requirements.

One Week

The kitten's ears will start to unfold and at around ten days their eyes will start to open. Kitten starts with blue eyes but they will most likely change when they grow up. Kittens still need to be kept warm and with feedings at regular intervals of every two to three hours. The kitten will need to be kept warm.

Two Weeks

The kitten's eyes are open their ear has unfurled. This is when the kitten will start taking its first wobbly steps (have your camera ready). The feeding will be on average every three to four hours. The kitten will still need to be kept warm.

Three Weeks 

A good way to tell that your kitten is about three weeks old is if it has teeth. But even if your kitten's teeth are emerging, they still need to be nursed or bottle-fed. The kitten will start to show its curious nature and take greater steps to explore the world around it (baby-proof the area, if it can hurt them they can find it). The kitten still needs to be kept warm.

Four Weeks

The kitten will get its canine teeth. Running, jumping, and playing are things the kitten can do now (the vase on the coffee table is no longer safe). It will still need the bottle and a heat source to keep warm when resting.

Five to Six Weeks

If you're wondering "how can I tell how old a kitten is by their teeth?", a good indication is their teeth. Five to six week old cats will have full mouth of baby teeth, including canines, molars, and premolars.

Seven to Eight Weeks

The kitten will eat wet food and their eyes will change from blue to adult color.

Essential Preventive Care for Kittens

No matter how old your kitten is you should take them for their first veterinary appointment during the first week they are in your care. Your veterinarian will evaluate the health of your kitten as well as inform you of their dietary needs. This also allows you to ask any questions you may have regarding the care of your new family member.

Regular wellness exams will give your kitten their best shot at a long and healthy life. These cat checkups allow your vet to assess your kitten's overall health and well-being, 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 its vaccinations and parasite prevention 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 five to six months old. This prevents any serious diseases or conditions from arising in the first place.

Signs That Your Kitten Should See a Vet

When caring for a kitten there are many things you need to keep an eye out for in every stage of your kitten's life, which could indicate a problem or even a veterinary emergency. If you see your kitten displaying any of the following signs call your vet immediately to schedule an appointment.
