Full Grown Maine Coon Cat: Size, Lifespan, Price & More

The majestic Maine Coon is one of the largest domesticated cat breeds. But what is owning a fully grown Maine Coon really like?

This guide covers everything you need to know about size, appearance, personality, care needs, costs and more for a full grown Maine Coon cat.

Size at Full Grown

Maine Coons are large cats. Male Maine Coons typically reach between 13-18 pounds as a full grown cat while females are slightly smaller at 8-13 pounds fully grown.

Their bodies are long and muscular with substantial bone structure to support their size.

To give a sense of their sizable stature, here are the average measurements of fully grown Maine Coons:

• Height:
  • Males: 14-16 inches tall shoulder height
  • Females: 12-14 inches tall shoulder height
• Length:
  • Males: 26-36 inches long nose to tail tip
  • Females: 24-32 inches long nose to tail tip
• Tail Length: 12-16 inches long, often as long as their body!

So in summary, a mature male Maine Coon is roughly knee-high to an average adult human with a 3 foot long body extending out to a 1-1.5 foot long tail. They are truly magnificent cats of impressive stature.

Weight at Full Grown

The average weight range for a fully grown Maine Coon is:

• Male: 13-18 lbs
• Female: 8-13 lbs

However, some exceptionally large males can weigh up to 25 pounds or more at full maturity. Proper nutrition is important to achieve a healthy weight.

Appearance at Full Grown

At full growth, Maine Coons showcase their luscious double coats and signature lion-like manes.

Their long, shaggy fur can be blue, silver, cream or mixed.

Ears are tufted and paws are large and round.

Tail lengths vary but are usually long and bushy.

Eyes are a bright copper color.

Personality at Full Grown

Fully grown Maine Coons tend to retain their affectionate, playful and gentle natures.

They bond closely with their families but can also be social with visitors. Highly intelligent, they enjoy interaction and mental stimulation.

Despite their large size, they are agile and enjoy climbing and jumping.

Price

Expect to pay between $1000-$2500 for a well-bred Maine Coon cat from a reputable breeder once fully grown depending on sex and pedigree. Adopting an adult Maine Coon from a shelter may cost $200-$500.

Food/Feeding

With their size comes high caloric needs. A fully grown Maine Coon eats 2-3 cups of premium dry or wet cat food divided into 2 meals daily. Fresh, clean water should always be available. Monitor weight and adjust feeding as needed.

Lifespan

Maine Coons have an average lifespan of 12-15 years when properly cared for but can live to be 18+ years old. Excellent genetics and preventative healthcare can help maximize a Maine Coon's longevity.

Health at Full Grown

Overall, Maine Coons are a hardy breed. However, they can be prone to hip dysplasia, obesity, diabetes and urinary issues due to their size. Brush teeth 2-3x week to prevent dental disease. Annual vet exams are recommended to monitor health and catch any potential issues early.

Care and Nutritional Needs at Full Grown

Beyond specialized large breed food, fully grown Maine Coons need:

• Brush coat 1-2x week to remove loose hair and distribute skin oils
• Trim nails as needed - usually every 4-6 weeks
• Brush teeth 2-3x week to remove plaque
• Clean ears weekly to prevent infection
• Provide ample scratching posts and places to climb
• Check and clean ears regularly to avoid ear mites and infections

• Misc. supplies: $200-500 annually for any emergency care, boarding etc.

Possible Behavioral Changes of a Fully Grown Cat

Most Maine Coons maintain their friendly temperaments as adults. However, females may be more aloof around strangers compared to when younger. Intact males may also demonstrate more territorial spraying behaviors than neutered males into adulthood if not properly trained and socialized.
