Maine Coon Kittens Double in Size in Just Days-and Everyone's Amazed
Normal kittens stay pretty tiny for a while. They're kittens! They're supposed to be small, and for the most part, they are... Except Maine Coons. Those kittens definitely didn't get the memo when it came to staying little.
Just look at these Maine Coon kittens. They're only three days old in the latter half of the video, and yet they're about the size of a regular kitten several weeks after they're born. It's honestly a little wild:
@mossycottagemainecoons It's incredible how quickly they start to grow and transform! #mainecoonkitten#growthupdate#mossycottagemainecoons#mainecooncat#kittenfever

Mossy Cottage Maine Coons has the coolest kittens. These have such a rich, deep grey/black color! The second kitten almost completely changes color in her 72-hour update: you can see the white on her snout disappearing. She's only going to get more vivid!
They're only 72 hours old in this video, though they're a little older now, which means they've probably at least doubled in size again. That's standard for a Maine Coon kitten: they grow almost uncontrollably for the first few months after they're born.

These two kittens in particular are turning into Mossy Cottage's new stars: they're the only two kittens in a litter named after mushrooms. The black kitten is Nameko, and the Tabby is Enoki. There's a better close-up video introducing them:

They're going to make the best playmates while they still can. Eventually, they'll go off to their forever homes, but hopefully, they'll always remember each other!
How Big Do Maine Coons Get?
If three days is any indication, Enoki and Nameko are going to grow up to be absolutely massive. All of the cats at Mossy Cottage, who are European Maine Coons, are on the larger side.
Maine Coons are one of the biggest cat species you can get. These cats can get truly massive, measuring:
- Up to 40 inches long, nose to tail.
- Up to 16 inches tall.
- Up to 25 pounds, though some of the largest exceed 30 pounds.
Male Maine Coons typically end up bigger than females, and they grow pretty rapidly. At about 18 months, they reach their full physical size, though growth, coat changes, and maturity continue for years after. These cats aren't technically full-grown until 4-5 years old!
These kittens have a way to go. I'll be happily watching as much as I can for as long as I can!
