One of my kitties (Manna) became part of my family at only 3 and half weeks old after being orphaned. It is amazing to watch kitten development! Kittens are born after a whirlwind 65 day gestation period. What happens in utero is remarkably similar to human development in utero. At birth kittens are 7 inches (17.78 cm) long and 3.5 ounces (99.2 g) on average. The next few weeks bring a stunning and beautiful transformation.
Kitten Development Birth – Week 2

At birth kittens are virtually helpless. Their eyes are shut, their ear canals are closed (ears folded over), and their motor skills are very limited. Two very important bodily functions are not yet under the kitten’s control:
- Body Temperature Regulation
Only able to produce a body temperature of about 95ºF (35ºC) and without the shivering reflex, the newborn kittens must cuddle closely with one another and their mother to stay warm. - Eliminating Urine and Feces
The mother cat will use her tongue to stimulate the kitten’s bodies to eliminate.
Kitten development progresses quickly. By week 2 the kittens’ senses, motor skills, and social abilities are already making gains. The kittens will open their big (most likely blue) eyes and see with blurry vision. The ears will begin to unfold and reactions to their Mother and other noises can be observed. Already, the kittens are gaining .36 ounces (10 g) in weight per day. It may be possible to determine the sex of the kitten at this time.
Week 2 marks the beginning of a very critical stage in kitten development. Between weeks 2 and 7 a cat will learn all it will ever know about socializing. It is crucial that cats are well socialized during this time so that they will be comfortable living with humans, other cats, and animals of other species.
Weeks 3-4

Much of the helplessness seen in the first 2 weeks of kitten development begins to disappear in weeks 3 and 4. The kittens can now regulate their own body temperature, eliminate waste on their own, are getting their baby teeth in, and are beginning to walk on their own. This is a great period of time to begin to introduce a small litter box to the kittens.
The big blue eyes are beginning to change to their permanent color. The kittens’ sight and hearing are almost as good as they will be when the kittens are adults. Depth perception is even beginning to develop.
Now that the kittens have use of their senses, socializing become more prominent. The kittens will begin to dabble in social play with one another and humans. This is where a kitten learns social rules and boundaries. For example, if little Manna bites little Cinco too hard, little Cinco will likely let out a little yelp and stop playing with little Manna. From this little Manna learns that she can’t bite others that hard if she wants positive attention from them.
Weeks 5-6

Weeks 5 and 6 are the true beginnings of kitten mischief. During these weeks of kitten development, the cats are fine tuning their motor skills and engaging in more complicated social interactions. At this point kittens have learned to run! They are capable of all of the same gaits that adults are capable of using. When playing with others, they begin displaying behaviors such as pouncing, rolling over and exposing their bellies, and side stepping. They will get into everything and anything.
This is the stage of kitten development where kitten food should be introduced. The kittens may not be completely weaned from their mother’s milk until week 9, but they will be open to trying the new food. Baby teeth may still be coming in, so softer foods may be preferable.
Another great introduction at this stage would be a scratching post. Those little claws are finally long enough that the kitten will begin stretching and sharpening them. It might not be possible to trim the kittens nails quite yet (that usually happens around week 10). Training a kitten to use a scratching post will be much easier at this stage than it will once the cat is an adult. It’s a good idea to begin teaching the kitten not to use their claws on humans (even in play) at this point too.
Other Important Notes about Kitten Development
- Kittens watch Mommy very closely.
One of the ways kittens learn about humans is by the way their mother interacts with humans. If the mother is afraid or anxious around humans, the kittens will likely feel the same way. Try to always have pleasant interactions with the mother cat. - Human touch is good for kittens.
Kittens that are regularly handled between kitten development weeks 2 and 7 developed more quickly and are more friendly to humans. - Orphaned kittens are at a huge disadvantage.
Orphaned cats often lack social skills, parenting skills, and are poor learners. If you have an orphaned kitty, the best thing you can do is try to get another cat mom to foster the kitten. However, this can be a difficult, if not impossible, task. You can raise a kitten as a human, but be careful to foster independence rather than reliance on you. Having another cat in the home can be very helpful too. - Socialization should include everyone.
It is helpful to introduce kittens that are in kitten development weeks 2-7 to as many different people and animals as possible; adults, children, men with beards, people in hats, tall people, short people, dogs, other cats, etc. The kitten will be uncomfortable at first, but will learn to enjoy the interaction. As a result, the kitten will grow to be more comfortable around different types of people and animals that they may encounter.
Do you have any tips for someone who might have a newborn/young kitten at home?

Great information. Thanks for sharing, pinned it!
Thank you so much! I really appreciate the pin 🙂 You are pawsome !
wow! This was super interesting! Thanks!
ღ husky hugz ღ frum our pack at Love is being owned by a husky!
You’re welcome! I’m glad you got something out of it. It really is amazing how they go from helpless to pawsome cats in no time flat.
Very good info for the humans. Thanks for enlightening them.
You are very welcome. I think that sometimes humans need to be reminded about how the awesome the world around them really is. We loose sight of that far too easily.
grate post guys….we troo lee due knot think dai$y wuz socialized prop er lee…two thiz day…N her iz all most 12 yeerz…. her haz onlee seen, haz been seen bye N will allow onlee three…. peepulz in two her…space…

I understand what you are saying. My poor Cinco wasn’t well socialized either. He hides whenever anyone but my husband and I are in our apartment. I guess I went wrong somewhere. At least he loves us though.
That really was good information…been a while since I was a kitten!
Thank you very much! It has been a while since my cats were kittens too. It is amazing to watch those little kitties grow though.
Very good post ! A friend of Mum had to raise orphan kittens ; the three babies were only 3 weeks old. With the help of her two cats, and the visits of many different humans, they turned into very well behaved and well-socialized cats (better than us we must admit) ! They all got adopted at 3 months old. Purrs
That’s a great story! I’m glad that your Mum’s friend was able to take such good care of those little kittens. It isn’t an easy task! It takes a very dedicated human to take on such a project.
Wow, kittens are a handful! I had NO idea how much work I was when I was that age. My human hasn’t had any kitten less than two months old since she’s been an adult, and never under 5 or 6 weeks old, so she’s never had the chance to experience most of this.
Little kittens are a lot of work! It is like raising a human baby only kittens grow up faster. In a way I miss having such a little kitten in my life! I’m really glad that I have healthy adult cats though.
This is great information. The head peep had to bottle feed kittens once, they were probably five weeks old. Not as small as some of the neonates in the photos above. This is a great resource for determining a kitten’s age.
Thank you very much! These milestones are a great way to think about how old a kitten might be. It is amazing how quickly they obtain all of these skills! I’m glad your head peep was patient enough to take on those little kittens.
This is GREAT info. I got Max when he was almost 4 month old. I got Bella from an empty apartment, so I don’t really know when she was born. Only advise I could give someone who is going to have kittens, is to keep them warm and let the mom do her job.
You are right, Joe! The best possible thing you can do is keep very young kittens with their mother. In cases where that is not possible, things get complicated. It takes a lot of patience to raise a little baby.
