Maine Coon Care Guide (Australia)

Last updated: 2026-07-20

The Maine Coon is a popular large-breed cat in Australia — among the biggest domestic cats, with a long, fluffy coat and tufted ears, an imposing look paired with a gentle, affectionate temperament often described as "dog-like". Adult females are typically about 4–7 kg and males about 6–10 kg, and many live 12.5+ years. They mature slowly and usually aren't fully grown until 3–4 years old. Heart disease and joint problems are the key health risks to watch in this large breed, and HCM screening is the critical question to ask a breeder.

Who is a Maine Coon right for?

Maine Coons suit families that want a big, friendly cat and are happy to provide space, grooming and sturdy furniture. They usually get along well with children and other pets. Not a good fit: small homes with no room for climbing or owners who don't want to brush regularly.

What does a Maine Coon kitten need?

The priorities in kittenhood are feeding for their longer growth period, starting grooming early and providing sturdy space to move.

Things to note

• Kittens usually go home from 12 weeks old — book a first vet check-up early to confirm the vaccination and worming schedule.
• The standard Australian kitten vaccination is F3 (feline panleukopenia, feline herpesvirus, feline calicivirus), with the first shot from around 6–8 weeks and boosters every few weeks as your vet schedules until around 16 weeks.
• Microchipping and council registration are legal requirements. Most councils have a curfew or indoor-containment rule for cats — check your local council's website.

Food & feeding

• Choose a kitten-specific formula. Maine Coons have a large frame and a long growth period — don't judge their body condition by the maturity timeline of an ordinary cat; be patient and let them grow into their size.
• Transition to new food over 7–10 days to avoid stomach upsets.

Behaviour & interaction

• Gentle and affectionate, not especially high-energy, but still needs a cat tree and scratching posts to burn off energy — their larger size also means they need more space to move.
• Start grooming training early with long-coated kittens, especially under the arms, belly and inner thighs — the earlier they get used to it, the easier it stays.
• Many Maine Coons love water and carrying toys around; combined with their curiosity and size, make sure furniture and benchtop items are secure so nothing gets knocked off and broken.

Common health risks

• Hypertrophic cardiomyopathy (HCM) is the most important inherited heart condition in Maine Coons — ask breeders whether kittens have had a cardiac ultrasound or genetic testing (including MYBPC3-related tests) before buying.
• Hip dysplasia and spinal muscular atrophy (SMA) are also documented in this breed — ask breeders about testing for these too.

How do you care for an adult Maine Coon?

• Mainly an indoor life; their larger size needs more room to move and climb — make sure cat trees are tall and sturdy enough to match their weight.
• Feed adult food to body condition score — despite their size, they can still gain weight, especially after desexing, so watch portions.
• Long coats need brushing several times a week to prevent matting and hairballs; in summer, talk to a groomer about a light trim.
• Common health risks: HCM needs regular cardiac checks (ask your vet how often to re-check), hip and spinal issues, and joint strain from excess weight.
• If allowed limited outdoor access, paralysis ticks in coastal and bushland areas can be fatal to cats too — follow your vet's advice for year-round prevention.

What changes for a senior Maine Coon?

• Switch to a senior formula and reduce calories to body condition. Weight, water intake and activity-level changes are the earliest warning signs — see a vet promptly if you notice a clear change.
• Senior Maine Coons need monitoring for HCM progression, arthritis and chronic kidney disease — more frequent check-ups are recommended; ask your vet for the right interval.
• Their large size means more strain on joints — provide low, easy-access beds and steps to reduce the impact of jumping.

Is a Maine Coon easy to train?

Trainability: Maine Coons are intelligent, affectionate and eager to interact, and can learn skills such as fetch.

Time to expect: a simple clicker-trained skill usually takes 1–2 sessions of 5–10 minutes to learn. Advanced skills like fetch are better spread over 2–3 weeks, building from "picks up the toy" to "brings it back to your hand".

The catch: Maine Coons are large and slow to mature (not fully grown until 3–4 years old); kittens are high-energy with short attention spans, so several short sessions under 5 minutes work better than one long one.

Simple steps (fetch):

1. Pick a small toy the cat already likes carrying (a pom-pom, a mini plush); click + reward whenever they pick it up.
2. Toss it a little further away; click + reward when they chase and pick it up, gradually extending distance.
3. When they carry the toy toward you, say "come" and reward once they reach you — reinforcing bringing it back rather than carrying it off.
4. Add the cue "fetch" before the toss, and repeat to lock in the full chain.

What's Australia-specific about owning a Maine Coon?

The Maine Coon is a popular large-breed cat in Australia, and HCM screening is the single most important question to ask a breeder — insist on seeing cardiac ultrasound or genetic-testing records, not just a pedigree certificate. Registration, microchipping and indoor-containment requirements for cats vary by state — if you're in a smaller apartment, weigh up whether there's enough space for a large-breed cat, and check your local council's website for the current rules. Being big doesn't mean more heat-tolerant — Australian summers still call for cooling and hydration, so avoid leaving them for long periods on an unshaded balcony or in a car.
