The largest cat breeds in the world are not just big in size, but big in heart. These massive bundles of fluff are energetic, adventurous, and full of life.
When it comes to domestic cat breeds, we’ve rounded up seven of the largest cats around. It may surprise you that some of these cats are larger than dogs, with some weighing up to 22lbs!
Sharing her tips for taking care of large breed cats, our vet, Dr Rebecca MacMillan, says, "Something that is easily overlooked is litter box size. Litter boxes need to be large enough for cats to position themselves, turn around, and dig in comfortably.
“You will also need to make sure that any cat trees, shelves, or perches are sturdy enough to take the weight of a large cat."
Now let’s check out which cats have topped the list of the largest cat breeds.
Largest cat breeds
1. Maine Coon
One of the most popular large cat breeds, the Maine Coon is a truly magnificent fluff ball. Entirely devoted to and affectionate with their owners, this gentle giant can weigh up to 22 pounds.
They’re known for their super-long tails, are playful, good with others (both young humans and the canine kind), and love exploring the outdoors.
Fun fact: the Guinness World Record holder for the world’s longest cat tail belongs to a Maine Coon – it measures 18.5in!
2. Ragamuffin
Famous for their big, mesmerizing eyes, the ragamuffin sports a super fluffy, almost teddy bear-like coat in a variety of colors. Weighing up to 20 pounds, this breed tends to take a little longer to mature, not reaching adulthood until they are four years old.
One fact about ragamuffins is that they have a calm and easygoing nature. Ragamuffins make for great family pets that often get along with other animals – you might even be able to teach them how to play fetch, master new tricks, or walk on a leash!
3. Ragdoll
Adorable by name, adorable by nature. Ragdolls got their cute name because they droop into their owner’s arms when picked up, exactly how a ragdoll does. They’re incredibly cuddly, affectionate, and docile in nature, which is why they are one of the best cats for dog owners.
They share ancestors with the ragamuffin, but are not the same breed. Ragdoll cats tend to have less color variation as well as oval-shaped eyes that are often blue.
4. Siberian
Weighing in as heavy as 18 pounds, this is a cat breed that loves cuddles. Siberian cats can be the perfect family pet with their playful personalities and sweet demeanor. This intelligent breed has the ability to adapt to its surroundings.
They have a water-resistant and oily coat, which is great for Siberians, as they are one of the cat breeds that like water.
5. Norwegian Forest Cat
There are so many things to love about Norwegian Forest cats. They are known for being intelligent, friendly, and extremely loyal companions. Weighing as much as 22 pounds, the Norwegian Forest cat is already a muscular-looking feline that sports an incredibly thick coat, making them look even bigger!
Their unusual name derives from a legend about a magical cat living in the forest that could disappear and reappear.
Norwegian Forest cats are often mistaken for Maine Coons, but you can read all about the differences between these two breeds in our Maine Coon vs Norewegian Forest cat comparsion.
6. Bengal
Easily mistaken for a wild cat due to its unique, patterned coat, the Bengal can reach heights of 10 inches and weigh in at around 18 pounds.
Just like you’d expect from a feline that looks like it belongs in the jungle, this breed loves to climb and will often spend its days playing and exploring. Incredibly people-oriented, this particular kitty enjoys getting involved in family activities.
7. Persian
Despite looking the part, Persian cats aren’t as large as they seem. These gorgeous kitties can weigh up to 15 pounds, but their incredibly plush, long fur coat makes them look much larger.
Persian cats are an extremely laid-back breed, but they’re also very intelligent, with some owners claiming to have taught their felines tricks. Given their long coat, it will require extra grooming, but as long as this is done daily, it will be very easy to maintain.
