Kitten Age: How to Tell How Old a Kitten Is

Kitten Age: How to Tell How Old a Kitten Is

Determining your kitten's approximate age is one of the first things you'll need to do so you can appropriately care for and nurture your new pet. Our Powder Springs vets offer some tips on estimating your young feline friend's age in this post. 

How to Tell How Old a Kitten Is

When you come across a kitten but have little to no background information on your cuddly new feline friend, what are you to do? How can you determine their age so you can take care of them as best as possible?

Your kitty's age is an important factor that your Powder Springs vet can use to guide you on caring for and socializing your pet. In this post, we'll explore how to assess physical characteristics to determine a kitten's approximate age. 

Week 1-2: Eyes Open

While kittens are born with their eyes closed and ears folded, their eyes will open once they are about 10 days old. At this point the eyes will be blue in color, and your kitty will be wobbly on their feet

Week 3: Teeth Emerge

Many new kitty owners wonder how to tell how old a kitten is by looking at its teeth. Baby teeth begin to emerge at around 3 weeks of age, with the canines emerging. Premolars erupt at about 5 weeks. Permanent teeth will erupt once they are three to four months old. 

At about 14 weeks, the middle incisors will come in, followed by the second and third incisors at about 15 and 16 weeks, respectively. 

Because kitten teeth are tiny, it can be challenging to tell whether the incisors are baby or permanent, but this gets easier when there are some of both to allow you to compare. 

While baby teeth are smaller with pointed tips, permanent teeth will be somewhat wider with flat edges. 

Your kitty's ears will also unfold at this age and they'll discover the litterbox and start to walk more confidently. 

Week 4: Kitten Gains Weight & Starts to Walk Well

Another good rule of thumb is that a kitten's weight in months roughly corresponds to her age in months. She will gain weight at a relatively predictable pace until she's about five months. 

As long as your kitten is healthy and developing normally, you can safely estimate that a 1-pound kitten is about 4 weeks old and a three-pound kitten is about 12 weeks old. 

Most kittens will start to walk at around three weeks old. This is an adorable phase to behold as coordination will take a little longer to master. You can guess that a kitten who has begun to walk well and play consistently is at least four weeks of age. 

Week 5: Time for Wet Kitten Food

During this phase, you'll be able to slowly wean your young cat onto wet kitten food. 

Week 6: Eating Confidently

By this point, all of a kitten's milk (deciduous) teeth will have emerged and they should be eating confidently. 

Week 7: Playtime

At this age, your kitten will start to show their personality as they become more playful and coordinated. They'll also begin to transition to their adult eye color. 

Week 8: Time to Meet Their Family 

At the eight-week mark, your kitten should weigh about two pounds. They can be neutered and spayed at this age, and meet their forever family.
