What are the largest cat breeds?

We all have our own likes and preferences when it comes to the pets we parent. Even though our pet's own personality is the most important part, looking at a select few breeds can help to narrow down our choices.

So, what if you’re a big fan of big cats? What are they like to own, and what are the largest cats in the world?

Here, we answer "what are the largest breeds of domestic cats", discuss their personalities, and share what being a pet parent to a big, gentle giant is really like.

What makes a cat breed “large”?

So, when answering "what are the largest house cats", what are we actually looking at? We’d categorise a big cat breed as one that has a body weight of around 15 pounds (lb) or more, a long body length and one that possesses a decent amount of muscle mass.

Common traits in big cat breeds are long limbs, thick fur (and higher grooming needs) and, typically, laid-back, easygoing temperaments. For cats, most of the bigger ones are genuine gentle giants.

Top six largest domestic cat breeds

As a note, we haven't listed breeds that are mixed with wild cats here.

Maine Coon

Maine Coon cats are probably the most famous of the feline gentle giants, and they’re a very popular pick for pet parents everywhere.

Friendly, social, affectionate, and great with families, these chilled-out kitties will settle into your lifestyle without much fuss.

They typically weigh between 13lbs and 18lbs, but males can reach 20lbs+. Maine Coon cats are synonymous with big domestic cats, and they could be a perfect match for you.

Norwegian Forest Cat

Friendly, sociable, and affectionate, Norwegian Forest Cats are intelligent, playful cats who can get seriously big. In fact, males can reach up to 20lbs, though most will sit in the 16-18lbs range.

Originating in the cold wilds of Scandinavia, Norwegian Forest Cats have long, dense fur that will need regular grooming, and they’ve adapted to the freezing temperatures with a lot of muscle mass, too.

But don’t let their big exterior put you off: a Norwegian Forest Cat will be an active, loving companion and a joy to pet parent.

Ragdoll

Known for going completely relaxed and limp in their pet parent’s arms, the very affectionate Ragdoll can get very big, with males sitting between 15-20lbs in weight. So, despite their big presence, they still stay relaxed and affectionate.

They’re described as “dog-like” due to the strong bonds they form with their pet parents, and they’re often the top choice for people who want affectionate cats.

If you’re looking for a relaxed lap cat that will love being a part of any family, then a Ragdoll is a strong choice.

Siberian

Siberian cats are a hardy, triple-coated breed from, you guessed it, Russia. They can typically reach sizes of 12-17lbs, and these big cats are known for being a friendly, affectionate breed that forms close bonds with their pet parents.

Despite their thick fur, they their grooming routine is relatively simple, though it’ll need regular brushing. Siberians love being a lap cat, and pet parents to them say they typically have an affectionate energy.

They're perfect if you want a big, fluffy cat that loves a cuddle and exudes positive energy.

British Shorthair

British Shorthairs have been getting more popular in recent years, and these cats have a lot of fans for their adorable looks and stocky, broad-chested frame. They’re actually one of the biggest domestic cat breeds you can own, and males can weigh between 12-17lbs.

They’re calm, affectionate cats who are known for being gentle. While affectionate, they’re reasonably independent too, and have been loyal, loving companions for pet parents for years.

So, if you want a chilled-out but affectionate big cat, a British Shorthair is a good choice.

Ragamuffin

Ragamuffins are a crossbreed between a Ragdoll and other long-haired breeds, like Persian and Himalayan cats. This gives them a striking appearance with Ragdoll-like personalities.

They love getting attention from their pet parents, and much like Ragdolls, they feel at home wrapped up in someone’s arms. Again, like Ragdolls, they’re big, reaching 15-20lbs.

If you want a big, friendly, and fluffy cat that lives and breathes affection, then we recommend the Ragamuffin.

How big is too big? Health considerations

Bigger cats may be more likely to face certain health issues, but this is true of all cat breeds; some are more likely to face certain health conditions that others.

So don’t worry too much. No matter what cat you pick, routine vet checkups are important, balanced diets are important, and creating a routine for exercising, socialising, playing, and looking after them is important.

Just pick the cat that feels right and one that your lifestyle can accommodate.

Should you adopt a large cat breed?

You know best as a pet parent (and you probably already know this) but consider factors like:

• Grooming needs, and if you have time to take care of your big cat’s coat

• Home space, and if there’s enough room for a big cat to play, explore and relax

• Your lifestyle and whether you have time to care for your cat’s emotional needs

Adopting a large cat breed comes down to you, the cat’s personality, and if you're a good match.

We know that you can research endlessly, but in the end, it comes down to which cat creates that spark and fits you, your lifestyle and your personality.
