How to tell a Maine Coon from a Norwegian Forest Cat
The fastest tell is the nose line, because the two breed standards ask for opposite shapes.
The profile test: curved vs straight nose
View your cat from the side, from forehead to nose tip. The CFA’s Maine Coon standard calls for a gently concave curve and rejects a straight line. The CFA’s Norwegian Forest Cat standard calls for exactly that straight line, with no break.
Head shape, legs and tail
- Muzzle: it should be visibly square in a Maine Coon. A square muzzle disqualifies a Norwegian Forest Cat at CFA shows.
- Head: a Maine Coon’s head is rectangular. A Norwegian Forest Cat’s forms an equilateral triangle.
- Hind legs: a Norwegian Forest Cat’s back legs are longer than its front legs, so its rump sits higher than its shoulders.
Can you tell from looks alone?
Not with certainty. Many random-bred longhaired cats share these traits, so only pedigree papers confirm a breed. Compare adults where you can, because a kitten’s head and coat are still developing.
A popular theory says the Norwegian Forest Cat is a Maine Coon ancestor, but it is unproven.
Which is bigger, a Maine Coon or a Norwegian Forest Cat?
The Maine Coon is usually bigger, and the CFA calls it the largest of all pedigreed cats.
Weight ranges from the registries
📊 Sourced: The CFA says it isn’t unusual for a mature Maine Coon male to reach or exceed 20 pounds, and females are usually smaller. It lists Norwegian Forest Cat males at 12 to 16 pounds and females at 9 to 12.
These are ranges, not targets.
Both take years to finish growing
🐾 Life-Stage Note: Don’t judge either breed at one year old. The CFA says Maine Coons can take up to three years to reach full growth, and Norwegian Forest Cats up to five.

Personality: which breed fits your home better?
Both breeds are gentle and family-friendly, but the registries describe different temperaments.
What the registries say
The CFA calls Maine Coons sociable, loyal and intelligent. It says they move from lap to lap rather than choosing a favorite.
It calls Norwegian Forest Cats independent and not clingy. They can be lap cats, but on their own terms. Both breeds chirp, and the CFA notes that Maine Coons aren’t a talkative breed.
Where popular sources disagree
⚠️ Watch Out: Popular breed sites contradict each other here. Some call the Maine Coon the better lap cat, and others call it the more aloof one. Meet the adult cats before you decide.
We grade the common claims in our Maine Coon personality fact check.
Kids, other cats and dogs
The CFA says both breeds get along with children and other pets. A Maine Coon’s size can startle them at first.
Coat, shedding and setting up for a big cat
Both breeds have long coats, but the coats are built differently.
Two different coats
A Maine Coon’s coat is shaggy and silky. It is shorter at the shoulders and longer on the belly and back legs, and the CFA suggests combing two or three times a week.
A Norwegian Forest Cat has a dense undercoat under glossy, water-resistant guard hairs. The CFA says it needs less upkeep than you might expect.
Our Maine Coon grooming routine covers the hands-on steps.
Seasonal shedding
🐾 Life-Stage Note: The CFA says a Norwegian Forest Cat’s coat is fullest in winter and needs extra combing in spring. Indoor cats tend to grow a less woolly undercoat, according to the American Cat Fanciers Association.
Space, climbing and litter boxes for a big cat
Norwegian Forest Cats love high places, so the CFA advises tall scratching posts or cat trees. For either breed, size the litter box to the cat. Our guide explains how many litter boxes you need and how big.
Health risks and DNA tests: how the breeds differ
Both breeds can develop heart disease, but their known inherited risks and DNA tests differ.
Heart disease (HCM) in each breed
Hypertrophic cardiomyopathy (HCM) thickens the heart muscle. Cornell’s overview of feline cardiomyopathy says it affects up to 15% of cats. It names an echocardiogram (heart ultrasound) as the gold-standard test.
Cornell lists the Maine Coon among breeds where HCM is more common. The CFA says HCM has also occurred in Norwegian Forest Cats.
Breed-specific DNA tests
| Breed | DNA test | Key detail |
|---|---|---|
| Maine Coon | HCM (A31P variant) | A clear result doesn’t rule out HCM |
| Maine Coon | Spinal muscular atrophy (SMA) | Signs appear around 3–4 months |
| Norwegian Forest Cat | Glycogen storage disease type IV (GSD IV) | Two copies cause a fatal disease |

UC Davis’s Maine Coon HCM test notes say HCM also occurs in Maine Coons that don’t carry the variant. UC Davis also offers a GSD IV test for Norwegian Forest Cats that identifies carriers. Our explainer covers what HCM DNA tests and heart scans can tell you.
🚨 Go to a Vet Now If: a cat of either breed is breathing fast or with effort at rest, collapses, or suddenly can’t use its back legs. Call an emergency veterinary clinic on the way.
Hips and lifespan
The CFA says Maine Coon breeders screen hips by X-ray. Ask a Norwegian Forest Cat breeder which hip checks they use. Lifespan estimates for both breeds vary by source, and we found no study comparing them directly.
Which breed should you choose? A quick fit check
Neither breed is better overall, so match the cat to your home.
Choose a Maine Coon if…
- You want the largest pedigreed breed and have room for oversized gear.
- You’d like a sociable cat that moves between family laps.
- You can comb two or three times a week.
Choose a Norwegian Forest Cat if…
- You prefer an independent, not-clingy companion.
- You can offer height, such as tall cat trees and shelves.
- You’re ready for a heavy spring shed and up to five years of growing.
Either way, the CFA says kittens of both breeds are generally not hard to find. Wanting a specific color or sex may mean a wait.

We found no direct comparison. Norwegian Forest Cats shed heavily in spring, and Maine Coons need combing two or three times weekly.
6. Is a Maine Coon or a Norwegian Forest Cat healthier?
Neither is proven healthier. Each breed has its own inherited risks and DNA tests, so ask breeders for both parents’ results and talk to your vet.

Yes. The CFA says HCM has occurred in Norwegian Forest Cats. Ask breeders about heart screening, and see a vet immediately for breathing trouble or collapse.
8. How long do Maine Coons and Norwegian Forest Cats live?
Estimates vary by source, and we found no study comparing Maine Coon and Norwegian Forest Cat lifespans directly, so treat any figure as rough.
