Found yourself dreaming about life with a large cat? You’re not the only one! Large cat breeds have developed a devoted following thanks to their striking stature, gentle temperament and affectionate nature.
Whether you're in the market for a new furry flatmate or you’re simply cat-curious, here's your guide to the largest cat breeds in Australia.
First, what counts as a large cat breed?
The average domestic cat weighs somewhere between 4 and 5kg. Large breeds tip the scales at 7 to 10kg, with some Maine Coons reaching a whopping 12kg or more!
Large cat breeds also tend to have longer bodies, broader chests and bigger bone structures than your typical tabby.
Large cat breeds in Australia
Maine Coon
The Maine Coon is the undisputed heavyweight of the domestic cat world. Curious, playful and sociable, their energy is more canine than cat-like. Don’t be surprised to find them waiting at the door or following you from room to room like a fluffy shadow.
Their bushy tails and gloriously shaggy coats make them extremely cuddly, and they’re surprisingly vocal – narrating their day with a repertoire of chirps and trills.
If you want a big cat with even bigger energy, this is your breed.
Norwegian Forest Cat
With a thick, water-resistant double coat (they’re built to survive Scandinavian winters, after all), slanting eyes and lynx-like ears, these regal cats look like they’ve wandered straight out of a fairytale forest.
They’re also natural explorers. Heights and hiding spots are non-negotiable for this breed. Give them a good cat tree and they'll be happy; deny them one and they'll find something else to climb.
Though they bond deeply with their families, they're affectionate on their own terms and happy in their own company. Less ‘desperate for attention’, more ‘comfortable in their own fur’.
Before bringing home a large-breed kitten, check that your everyday cat essentials are big-cat friendly. Standard litter trays, carriers and scratching posts can quickly become too small once breeds like Maine Coons or Ragdolls reach their full size.
Ragdoll
Ragdolls are the ultimate teddy bears. Complete with plush, silky fur and soulful blue eyes, they get their name for their endearing habit of going limp when they’re picked up. And honestly, that tells you everything you need to know.
Weighing up to 9kg, these are calm, gentle giants – perfectly happy to be carried around like a baby or lie draped across your lap for hours at a time.
Adventure and mischief? Not their style. Adoring their human is their full-time job. Ideal for anyone who wants a laid-back cuddle companion rather than a live wire.
Siberian
Don't let the Siberian's luxurious coat fool you. Underneath all that fur is an athletic, agile cat with a playful streak. One of the more interactive large breeds, Siberians love games, puzzle feeders and anything that gives them a mental challenge.
Warm and affectionate without being needy, they can take the chaos of a busy household in their stride, making them a great fit for owners with kids or other pets.
They also produce lower levels of the sneeze-inducing Fel d1 protein that causes most cat allergies, which is potentially great news for anyone who’s spent years loving cats from a safe distance.
British Shorthair
The British Shorthair is as steadfast and dignified as its namesake. Placid and undemanding, they’re not lap cats in the traditional sense, but they’re loyal and steady companions who keep a watchful eye over their loved ones – even if it’s from a distance.
Their independence makes them well suited to quieter households or owners who want company without the clinginess.
Weighing in at 4-8kg, they’re smaller than some of the breeds on this list, but their stocky build, dense coats and distinctive round faces give them a characterful charm that’s hard to resist.
Bengal
Descended from the Asian leopard cat, the Bengal cat is in a league of its own. High-energy, highly intelligent and easily bored, they need plenty of stimulation. But for owners who can match their energy, they're endlessly rewarding pets.
Their sleek, spotted coat stops people in their tracks, but it’s their personality that really sets them apart.
Exceptional jumpers, no shelf or door top is off limits.
Unlike most cats, they’re fascinated by water (so may try to join you in the shower if you’ll let them). And if they want something? You’ll hear about it. Bengals are far more vocal than your average domestic breed.
But despite their wild energy, they form strong bonds with their owners. Life with a Bengal is never dull.
Things to consider before going for the biggest cat breed
Big cats bring big personality. But they also bring bigger everything else: bigger bed, bigger food bill, bigger presence in your home.
Below are a few practical considerations worth thinking through before you commit.
- Space: Large cats need room to move, climb and explore. This is especially true for active breeds like Bengals and Norwegian Forest Cats, who need vertical space as much as floor space.
Need a big bed for a big cat? Shop cat beds.
- Feeding costs: A bigger cat means a bigger appetite. Large breeds generally need more food than your average domestic cat, so factor that into your budget. The right diet will vary depending on breed, age and activity level, so it's worth doing your research.
Find the right food for your cat, no matter the size. Shop cat food.
- Grooming: Several breeds on this list – Maine Coons, Norwegian Forest Cats and Siberians in particular – have long, thick coats that need regular brushing to prevent their coats from getting matted. You’ll need to put aside time for this at least once a week, or else factor in the cost of professional grooming.
- Vet costs: From anaesthetic doses to medication, larger cats can be more expensive to treat simply by virtue of their size. It's worth looking into pet insurance early before any health issues arise.
- Slow growth: Most large breeds don't reach their full size until three to five years old. That's a long kittenhood, which can mean an extended period of mischief and high energy – particularly for some breeds. Be prepared for the long game.
How to find large kitten breeds
If you've settled on a large breed, the next step is finding one – and you may need to be patient.
Popular breeds like Maine Coons and Ragdolls are in high demand across Australia, and reputable breeders often have waitlists of several months. Look for breeders registered with your state's cat council, and don't be afraid to ask questions about health testing, living conditions and how kittens are socialised.
If you'd rather not wait, adoption is always worth considering. Large breeds (or large breed mixes) do occasionally come through rescue organisations and shelters, and the staff will usually be able to give you a good read on their personality and needs.
