I think it depends on the breed too. Some being up to 3 years or so. Even though he's a mix, my Sho still looked like a kitten (albeit a big one) till he was around 3 years old.

Generally speaking, 1 year is the accepted age that they stop growing and are considered "adults".

However, there are breeds that continue to grow until they are 2+ years. The larger breeds, like Maine Coon and Ragdoll, are examples of this. I also believe that Siamese generally develop slower than other breeds (which is why a good breeder absolutely will not let a Meezer go before 12-16 weeks old), and they shouldn't be bred until later than is generally accepted for other breeds.

So, if there are other breeds in a moggy, they could continue to grow past one year, but that is the accepted age of adulthood for moggies and most breeds.

I was thinking a year, based on the amount you feed a cat. A lot of the packages I have looked at, suggest that generally the amount of food a cat should eat is either based on weight or years. And I have found that an adult cat is generally a yr.

In the case of Zoey I thought she was done sixth months ago at about 2.5 yrs but she is back growing/.... Somedays I think something really big got in her genes

There's no place like home
My friend's cat appears to have finally stopped growing. He'll be 3 years old in a few days. As of last week's vet appointment, he weighs in at 21 pounds. His vet is not concerned about his weight - it's normal to his frame size. We know he is an Angora mix, and by his size he has to have some Maine Coon in him.

The bigger the cat, the longer it takes for them to reach full size.

All my boys (aged 2 1/2- 3 1/2) have stopped growing, other than Cappy, who is almost 9 months old. He's got awhile to go yet.

Nacho and Orion seemed to stop growing at just over a year. Where as Poptart and Gordito just kept getting bigger and bigger till they outgrew the older boys. They were close to 2 when they stopped.

I'm glad this question was asked. I was just looking at my kittens the other day and wondering how much bigger they'll get. They're nearly 7 months so I guess we've got a bit of growing left to do!

Stumpy's a little over 1 year old and Lily is about 9 months old, and they've both looked the same size for a few months now. I don't think Lily will get much bigger. She lost her kitten look by about 6 months old

My Smudge is 6 months old, and still "looks" like a kitten, and I think has a lot more growing to do still.

So I think it very much depends on the cat. Even if your boy grows some more, I imagine he wouldn't get much bigger than what he is now.

Everyone has posted good info, but I wanted to add one thing but don't want to worry you. If a cat is sick, they can grow very slowly. An ex-gf and I adopted Taylor with his litter mate. She took the litter mate. We'd take them in at the same to get shots, etc and Taylor was growing normally while the other one was not. After about 6 months, the little guy became real sick and was diagnosed with FIP.
