When do kittens stop growing?

I receieved my Tiger-Wiger the first week of November and she was tiny enough both my small hands covered her. I could easily hold her in one hand. I was told she was near 10 to 12 weeks, making her a July/August/September kitty.

On March 29, the vet said she was no where near 8 or 9 months old, more like 6. Now I'm looking at September/October kitty, half of what age I had been told. Now mid-July, she is still growing and I swear she just grew an inch overnight! Also, her whiskers ate starting to get very long and break off.

When do kittens stop growing and reach adulthood? How old is my Tiger?

Not sure if this helps any, but the last time I could hold my kitten so that both hands covered her, she was around 3-4 weeks old. The last kitten I saw grow to maturity took almost three years to stop growing (noticeably, anyways.) Aside from his gut, that is.  But, a friend of mine has naturally very small cats, Manx ones, that stopped growing around 4-5 months. They were so small! I'd guess it depends on your kittens ancestry.

There is some variation. The big longhaired breeds (Main Coons, Norwegian Forests, and Ragdolls) mature slower than Persians and shorthair cats. I think most cats stop growing close to their first birthday, but can't remember when mine did.

She was so small I unzipped my coat and put her down the hole on my chest and zipped it back up over her. I did that because she was shivering, terrified and cold. She purred herself to sleep. 

She's a long haired gray tabby. 

12-24 months would be the average age cats stop growing

Size isn't a good indication of age, it can depend on genetics and the start kitten has in life. Teeth are a better way to tell age, eye colour also provides clues.

The last baby tooth she lost was in March.  Her eyes have have been brillant green since I had her.

 Anyone who read about Delilah (there are several threads about her) knows a kitten can be much smaller than her age. Of course if a kitten has no medical problems growing up, the reason would be different.

Cookie stopped growing at 12 months. But that could be just her, because she's the size of a bear!! :lol3:

What breed or combination of breeds is Cookie?
