So, you want a cat that looks like it could double as a footstool or maybe a small mountain lion? I get it. There is something inherently cool about sharing your couch with a feline that actually takes up half of it. But if you’ve spent any time Googling the biggest cat in the world breed, you’ve probably noticed a lot of conflicting info. Some people swear it’s the Savannah. Others point to the Maine Coon.
Here is the truth: it depends on how you measure "big."
If we are talking about pure height, the Savannah cat usually takes the crown. If you are looking at length and sheer "room-filling" presence, the Maine Coon is king. Honestly, the world of giant cats is a bit of a rabbit hole filled with hybrids, genetic quirks, and some very lucky Italians.

The Maine Coon: The Heavyweight Champion of Your Heart
Most people consider the Maine Coon the definitive biggest cat in the world breed because it is 100% domestic. You don't need a special permit to own one, and they won't try to parkour off your ceiling at 3:00 AM like some of the wilder hybrids.
These guys are absolute units. A typical male can easily hit 18 to 22 pounds. Some rare cases even push 25 or 30 pounds without being overweight.
They are long. Really long.
Take Barivel, for example. He’s a Maine Coon living in Italy who currently holds the Guinness World Record for the longest living domestic cat. He measures a staggering 47 inches. That is nearly four feet of cat. Imagine that stretched out on your bed. You're sleeping on the edge; that’s just the rule.
Why are they so massive?
It mostly comes down to their history. They didn't start as pampered house pets. They were rugged working cats in Maine, built to survive brutal New England winters. They needed those massive "snowshoe" paws to walk on drifts and that thick, water-repellent coat to stay dry.
Everything about them is oversized:
- The Tail: It’s often as long as their body, used like a warm scarf when they curl up.
- The Ears: Big, tufted, and very "lynx-like."
- The Personality: They’re called "Gentle Giants" for a reason. They don't really meow; they trill and chirp. It’s kinda hilarious to hear a 20-pound beast make a tiny "brrrpt" sound because you walked into the kitchen.
The Savannah Cat: The Tall, Lean Alternative
If the Maine Coon is a sturdy SUV, the Savannah is a Ferrari.
This breed is a hybrid—a cross between a domestic cat and an African Serval. Because they have recent wild ancestry, they are leggy, lean, and incredibly tall. The tallest cat ever recorded was a Savannah named Arcturus, who stood over 19 inches tall at the shoulder.
But there’s a catch.

Savannah size varies wildly based on their "F" generation. An F1 Savannah (50% wild) is going to be a giant. An F5 Savannah (several generations removed) might be the size of a regular house cat.
Owning an F1 or F2 is basically like living with a small leopard. They can jump 8 feet into the air. They like water. They are intense. If you're looking for a lazy lap cat, this isn't it. You’ve been warned.
The "Other" Giants You Probably Overlooked
While everyone argues about Maine Coons and Savannahs, a few other breeds are quietly taking up too much space on the rug.
- The Norwegian Forest Cat: Often confused with the Maine Coon, these "Wegies" are built for the mountains. They have a double-layered coat that makes them look even bigger than they are. They’re heavy-boned and can weigh up to 20 pounds.
- The Ragdoll: These are the heavyweights of the "indoor-only" world. They don't have the wild look of a Savannah or the ruggedness of a Maine Coon. They are just big, floppy, blue-eyed clouds of fur. A male Ragdoll can easily hit 20 pounds.
- The Chausie: Another hybrid (Jungle Cat cross). They are long, muscular, and look like they belong in a temple in ancient Egypt. They can reach 25 pounds, but like the Savannah, they require a lot of "activity" to keep them from redesigning your curtains.
The Reality of Living With a "Goliath" Feline
Buying or adopting the biggest cat in the world breed sounds like a dream until you realize your house isn't built for them.
Standard cat trees? Forget it. They’ll snap the poles or the whole thing will tip over the first time the cat tries to climb it. You need furniture built from solid wood or PVC.
Litter boxes are another issue. Most "large" boxes at the pet store are still too small for a 4-foot-long Maine Coon. Many owners end up using those giant plastic storage bins with a hole cut in the side. It's not glamorous, but it works.
And the food. Oh, the food.
A 22-pound cat eats significantly more than a 7-pound tabby. You aren't just buying bigger bags; you’re buying them twice as often. Plus, big breeds are prone to specific health issues like hip dysplasia and heart problems (specifically HCM). Keeping them at a healthy weight is vital because an "extra" 3 pounds on a big cat puts massive strain on their joints.
Is a Giant Breed Right For You?
Before you run out and find a breeder, think about your lifestyle. These cats aren't just bigger; they are more. More fur, more food, more personality, and—let's be honest—more poop.
If you want a dog in a cat’s body, the Maine Coon is your best bet. If you want a high-energy athlete that requires 2 hours of play a day, look at the Savannah.

Actionable Next Steps
- Check Local Laws: If you're looking at Savannahs or Chausies, check your state and city ordinances. Some places ban early-generation hybrids.
- Measure Your Space: Ensure you have room for a "jumbo" litter box and a sturdy, wide-based cat tree.
- Find a Specialized Vet: Not all vets are used to the specific health screenings needed for giant breeds. Ask about their experience with HCM (Hypertrophic Cardiomyopathy) testing.
- Budget for the Long Haul: Factor in the higher cost of high-protein food and larger doses of flea/tick preventatives, which are often priced by weight.
The biggest cat in the world breed isn't just a trophy; it’s a massive commitment that will likely follow you from room to room, chirping for snacks and taking up every square inch of your personal space. And honestly? Most owners wouldn't have it any other way.
