Adult Maine Coons: Big Cats, Big Personalities!

Jennifer in Los Angeles asks: "Hello, I have a question about adopting an adult Maine Coon. I’ve always assumed that if I brought a Maine Coon into my home, it would be as a kitten.

However, I now have an opportunity to adopt a retired breeding female from a reputable cattery. She is four years old, healthy, and well-socialized, according to the breeder.

I would love to hear your thoughts on what I should consider before making this decision.

How might adopting an adult Maine Coon differ from raising a kitten? Are there any special challenges or benefits I should be aware of?

I want to be sure I’m making the right choice for both myself and the cat.

Thank you!"

Hi Jennifer!
Thank you for your thoughtful question! Adopting an adult Maine Coon - especially a retired breeding cat - can be a wonderful experience, but it does come with some differences compared to raising a kitten.

Since she is four years old, she already has a fully developed personality, which means you’ll have a good sense of her temperament right from the start.

Unlike a kitten, she probably won’t go through unpredictable phases of high-energy zoomies or mischief, but she’ll still be playful and affectionate in her own way.

Regarding diet, adult Maine Coons require high-quality, protein-rich food to maintain their muscle mass and coat health.

Since she’s no longer growing, portion control becomes more important to prevent excess weight gain, which is common in the breed.

If she has been eating a diet formulated for breeding cats, you may need to transition her gradually to an adult maintenance diet.

Grooming is another key consideration. Unlike kittens, whose coats are still developing, an adult Maine Coon has a full, thick coat that requires regular upkeep.

Expect to brush her at least a few times a week, especially around her ruff, belly, and tail, where tangles can form. If she’s used to being groomed, this should be an easy routine to maintain.

As for the transition from a cattery to a home, she should adjust fairly smoothly! Retired Coonies are usually confident and well-adjusted.

If you’re prepared for the adjustment period and ongoing grooming, I think you’ll find that adopting an adult Maine Coon is an incredibly rewarding experience.

Let me know if you have any other questions - I’d be happy to help!

Best Wishes,
Carrie

The Maine Coon in Adulthood

This breed is known for its impressive size, luxurious coat, and affectionate personality - but what happens when this breed reaches adulthood?

While kittens are full of playful energy and curiosity, adult Maine Coons settle into their full personalities, often becoming even more loyal and loving companions.

One of the most noticeable differences between a kitten and an adult Maine Coon is size. This breed grows slowly, taking up to four or five years to fully mature!

Their long, muscular bodies and bushy tails become more pronounced, giving them the regal look they’re known for. Their coats develop fully in adulthood, featuring a dense undercoat and long, water-resistant guard hairs.

Temperament-wise, adult Coonies tend to be laid-back but still playful. They often retain their kitten-like curiosity, but they are generally less hyperactive than their younger counterparts.

While kittens are busy exploring, climbing, and getting into mischief, an adult is more likely to lounge nearby, keeping a watchful eye on the household.

Their grooming needs also increase with age, as their thick coats require more regular brushing to prevent tangles.

Owning an adult Maine Coon means enjoying the best of both worlds - a gentle giant with an affectionate nature and a stunning, fully developed appearance.

Size and Appearance of an Adult Maine Coon

A fully grown Maine Coon is one of the largest domestic cat breeds, with males typically being larger than females.

On average, an adult male weighs between 13 to 18 pounds, though some can exceed 20 pounds.

Females tend to be slightly smaller, usually ranging from 8 to 12 pounds. In terms of length, including their long, flowing tails, Coonsies can measure up to 40 inches from nose to tail tip.

Their size isn’t the only thing that sets them apart - adult Maine Coons have a strikingly thick and shaggy coat that reaches full maturity around three to four years old.

Their fur is longer around the neck, chest, and tail, forming a lion-like mane and a plume-like tail that they often wrap around themselves for warmth.

Unlike kittens, whose coats may appear soft and fluffy but not fully developed, adults have a dense, water-repellent double coat designed to withstand cold climates.

Coonies have large, tufted ears that add to their wild appearance. These ear tufts, known as lynx tips, often become more pronounced as they mature.

Their paws are another notable feature - large and tufted, they act as natural “snowshoes,” helping them navigate different surfaces with ease.

The way a Maine Coon grows from a playful kitten into a full-grown, stunning adult is pretty amazing.

With their big, fluffy tails, tufted ears, and thick coats, they turn into some of the most striking cats you’ll ever see!

Personality and Behavior of an Adult Maine Coon

Adult Maine Coons are affectionate, playful, and intelligent - but in a more laid-back way than their kitten days.

As youngsters, they’re full of energy, climbing, pouncing, and zooming everywhere. Over time, they mellow out but keep their fun-loving nature.

They’re loyal cats who like to be near their people, following them from room to room. Sometimes lap cats, and always companions, watching everything with those big, curious eyes.

Some owners wonder if they get more independent with age. While they might not demand as much attention as a kitten, they still love companionship. They adapt well to different households and thrive on routine.

Their intelligence remains sharp, so they enjoy puzzle toys, training, and interactive play.

Many keep their kitten-like quirks - chirping at birds, chasing toys, or even playing in water.

Others pick up new, oddball habits, like carrying socks around or fetching random objects. Always entertaining, no matter their age.

Care and Maintenance

Diet and Nutrition

A fully grown Maine Coon needs a balanced diet with plenty of high-quality protein. Wet food is a great choice to keep them hydrated, but a mix of wet and dry food can work well. Look for options with real meat as the first ingredient and avoid fillers like corn or soy.

Follow feeding guidelines based on weight and activity level, and adjust if needed. Treats should be given in moderation.

Grooming Needs

Their thick coat needs regular care to stay soft and tangle-free. Brushing two to three times a week helps reduce shedding and prevents mats.

During spring and fall, when they shed more, daily brushing might be helpful. A stainless steel comb and a soft bristle brush work best.

Bathing is rarely needed, but a gentle wipe with a damp cloth can help with dirt or dander. Regular nail trims and ear checks are also part of keeping them comfortable and healthy.

Exercise and Play

Even though they are more relaxed than kittens, adult Maine Coons still need daily playtime. This helps maintain a healthy weight and prevents boredom.

Wand toys, feather chasers, and climbing structures keep them active. They also love puzzle feeders that challenge their minds.

Some enjoy leash training and short outdoor adventures in a secure area. Others prefer climbing cat trees and watching the world from a high perch.

Health and Lifespan

Maine Coons are generally healthy with a long lifespan! But they can develop conditions like hypertrophic cardiomyopathy (HCM), hip dysplasia, polycystic kidney disease (PKD), and spinal muscular atrophy (SMA).

Regular vet checkups and weight management help reduce risks of these possible health issues.

Kitten vs. Adult Maine Coon: Key Differences

Energy Levels and Behavior Changes

Kittens are tiny bundles of energy. They race around, climb everything, and explore nonstop. Adults still love to play but are more controlled in their movements. They’re happy to chase a toy, then relax for a while.

An adult Maine Coon is less likely to engage in nonstop zoomies at 2 a.m. They still have bursts of activity, but they also appreciate quiet time.

This makes them a great fit for someone who wants a playful yet calm companion.

Training and Socialization - What’s Easier with an Adult?

Kittens require patience and training. They need to learn litter box habits, scratching post use, and household rules.

An older cat usually has these basics down. They understand routines, making them easier to integrate into a new home.

Socialization varies. Kittens are adaptable but require guidance. Adults may take a little longer to adjust to change, but their personalities are already developed. You know what you’re getting in terms of temperament.

Which Is Better for Different Lifestyles?

Kittens need constant supervision. They get into mischief, chew on things, and require plenty of attention.

If you have a busy schedule, an adult cat might be a better choice. They are independent but still affectionate and engaging.

Families with young children may enjoy the playful nature of a kitten. However, an older cat can be a great match for someone wanting a relaxed but still interactive pet.

Either way, Maine Coons make wonderful companions at any age!

Adopting an Adult Maine Coon

Bringing home an adult Maine Coon? That’s an exciting (and usually pretty smooth) experience.

These cats already have their personalities figured out, so you’ll know right away if they’re a good match for your home.

A lot of people actually prefer adopting an adult over a kitten. No kitten zoomies at 3 AM, no litter box training, and no "I just climbed your curtains because I could" moments.

Adults tend to be more relaxed, and their habits are already in place. If you’re looking for a chill, predictable companion, an adult Maine Coon might be perfect.

---

There’s just something special about an adult Maine Coon. They’re affectionate, smart, and packed with personality.

Whether you’re bringing one home for the first time or already have one ruling your house, understanding their needs keeps them happy.

And really, at any age, they’re impossible not to love.
