At what age is a cat fully grown?

post #1 of 19
Thread Starter 
As some of you know, I have a kitten - Stella.

In either December or January, she will be 1 year old.

She is still pretty little - about 14 inches in length not including her tail.

Is this normal at her age? What age is a female cat fully grown?

A cat usually is fully grown/development at about 2 yrs old. Some smaller breeds like Rexes would be full grown by 14 months; Maine Coons would take 4 yrs.

Usually by about 12-16 months they are pretty much as big as they will get and only fill out a little more, or if longhair, develop a heavier coat.

Keep in mind that females are smaller then males.

Polly is really small, too. She's just built that way. Some kitties are just smaller than others. She stopped growing at about 12 months.
Unless Stella is showing signs of being unhealthy I wouldn't worry too much.

Thanks for the responses - Stella is a healthy cat, just really little It is so cute. I had a friend who had a cat that was fully grown and it was kitten sized - it was the cutest thing!

I am wondering if Stella was the runt of the litter...I will never know because she was found in the middle of the road.

It probably doesn't help having two boys as your other cats. My Fluffy is only 4kg fully grown

No - especially with Peedoodle who causes people to go "whoa! he's huge" when they see him!

Stella is such a cutie. Molly takes after her dad, in coloring and the more solid build. Polly's just like her mom- healthy but very petite.

Taz isn't a Maine Coon but he is very similar in a lot of ways. He wieghs 19 pounds (big, not fat) and he grew until he was around 3 years of age.

Years ago we had a little tori-tabby, Mitzi, whom we lost in 2005 at 14.

She was always under 10 pounds and seemed to stop growing at about 1 year.

I guess they vary.

My Mittens is an example of a small full grown kitty. She still looks like she did when I got her - and she was an older kitten at that time. My boyfriend's mom refers to her as "solid", small and packed with muscle. We wonder if she was the runt of the litter. She is significantly smaller than Monster, but healthy.

Monster is my big boy who makes people say "WOW, he is SOO huge! I've never seen such a big cat!" He weighs about 16 lbs, people think he is fat, but what looks like fat is just a whole heck of a lot of fur. When he gets a bath you can clearly see he isn't fat. He is a big bone kitty, HUGE paws and was just meant to be well, HUGE. He's extremely healthy according to the vet, and while 16 lbs sound too heavy, its the purrrfect weight for a cat of his frame. (Even though he is definitely a moggie, I think that somewhere along the line there was a Maine Coon in his family)

IDK if Rosalie's just BIG or Zoey's just tiny (although I see it as Zoey being tiny) but when I picked up Zoey at 10 weeks she was the same size (maybe smaller) as Rosalie when I got her (which was 6 weeks old). Currently Rosalie (at 4 months) is bigger/the same size than my friends 6-7 month old male kitten.

A lot of people think Molly is the mom and Polly is her baby.

(In reality they are littermates- the same age.)

LMAO! Omgoodness I've gotten that too, a lot of people think Rosalie is Zoey's mama but they're 6.5 weeks apart (July 26 and Sept 10)

It depends on their breed, mixes, and if they are male or female...
Ragdolls are fully grown only by 4 years old!! That means I will end up with a HUGE kitty here! Bugsy, my male Raggie, is very looooong and also a bit chubby - currently about 18lbs, and 2 1/2 yr old. Lucky, my female raggie, is smaller but still a big kitty IMO - she is about 13lbs, quite long and tall, lean, and will be 2 in March. Hope is 9lbs and looks tiny compared to the other two... so cute! She is going to be 3 soon - since she is just a DLH, I am pretty sure she is fully grown.

I have a mixed Bengal and she is about 16 months. She is very long but very petite. She hasn't grown in a few munths but while the father was a large Bengal,her mother was a small domestic longhair.She still seems like a kitten but I don;t think she'll get too much larger. I hope not,she is like having a kitten all the time. Shes actually a juvenile delinquent! She was a birthday gift and I couldn't have gotten a more treasured one!

Welcome to TCS wavey.gif We'd love to hear more about your kitty. You probably didn't notice that this thread is 3 years old. I'm sure more people will see your post if you introduce yourself in the New Cats on the Block forum.

Hey everyone.    My hubby and I adopted a tabby kitten a few months ago.   Her name is Ella, and now she's 6 months old.    I was wondering what age a female cat is fully grown for a tabby.

It depends on what you really mean. Literally I would say about 12 months, perhaps even somewhat more. Longhaired often later still. 

But if you mean when they can come in heat / get kittens, so she is already in the high risk zone. Anywhere now.

So careful with boys!!!  And double careful with adult experienced toms, who knows what to do and how, and can do it quickly, perhaps before you blink! 

 

If you arent a breeder, best and simplest for all is to spay.

 

Welcome to our Forums!

 

Good luck!

Stefanz is right about the risk of pregnancy.  If you haven't already had her spayed, do so ASAP.

She has been spayed.    The shelter spayed her a couple of days before hubby and I adopted her.
