Standard cat carriers are designed around an “average” cat of about 8-10 lb. If yours is a Maine Coon, a Ragdoll, a chunky British Shorthair or simply a big domestic cat, you already know how that ends: the cat has to fold itself in like luggage, the door won’t quite close without a shove, and by the time you reach the vet both of you are frazzled. A too-small carrier isn’t just undignified — a cat that can’t stand, turn round and lie stretched out will panic more, fight loading every time, and associate the box with stress.
That is why owners of big cats search for the best cat carriers for large cats: carriers honestly sized for cats in the 12-22 lb range and beyond. But “large” on a listing can mean anything, so the numbers that matter are the interior dimensions in inches compared with your cat’s length and height — not the headline alone. Measure your cat from the tip of the nose to the base of the tail, and from the floor to the top of the head or ears. The carrier’s interior should be at least that long, ideally with a couple of inches to spare, and tall enough for your cat to stand without ducking.
We compared the leading Amazon options on true internal space, manufacturer weight ratings, door design (top-loading vs front vs walk-in side door), base rigidity and build quality — and narrowed it down to these five, covering hard kennels, a genuinely airline-leaning soft carrier, and one extra-large soft carrier big enough for the very largest cats.

What to Look for in a Carrier for a Large Cat
- Interior dimensions, not the label: Measure your cat nose-to-tail-base and floor-to-ears (in cm, a big cat is often 45-50 cm long). Exterior measurements include handles and trims, so look for listed interior space and give your cat room to stand, turn and lie fully stretched.
- A weight rating with headroom: Choose a carrier rated comfortably above your cat’s actual weight. A 17 lb Maine Coon in a carrier “up to 15 lb” is a latch failure waiting to happen.
- Top-loading or a wide door: Lowering a cat in from above — or letting them walk in through a wide side door — is far less stressful than posting them head-first through a narrow front gate. Top-loaders are also much easier at the vet’s, where the cat can often be examined in the open bottom half.
- A base that doesn’t sag: Heavy cats make soft carrier floors bow and roll, which frightens them. Look for a rigid plastic shell, a framed soft carrier with metal support, or a firm board base.
- Security: Steel doors, locking zips and sturdy latches matter more with a strong, heavy cat. A determined 18 lb cat can burst a weak zip or flex a flimsy door.
- Be honest about flying: Most in-cabin pet spaces fit carriers of roughly 18 x 11 x 11 in and cats well under 20 lb — a truly large cat may simply not qualify for the cabin, whatever a listing implies. Only trust airline claims a listing actually makes, and always confirm with your specific airline before booking.
1. SportPet Designs XL Cat Carrier — Best Overall for Big Cats
SportPet Designs XL Cat Carrier
This is the carrier we would point most large-cat owners to first. SportPet designed it specifically for cats rather than shrinking a dog crate: the patented wide side-opening door lets your cat walk in at floor level instead of being pushed through a front hole, which removes half the loading battle at a stroke. The interior is genuinely roomy — the listing gives dimensions of about 23.1 in long x 18.8 in wide x 17.3 in high — and it is rated for pets up to 35 lb, giving real headroom for big Maine Coons and Ragdolls. It currently sits at number 1 in Amazon’s Cat Hard-Sided Carriers category.
The shell is hard, impact-resistant plastic with rounded ventilation slats for airflow, and the whole carrier folds flat for storage — a rare trick for a hard carrier. The wide door also makes cleaning easy after travel accidents, and a waterproof bed version is offered on the same listing.
Pros: Walk-in side door dramatically reduces loading stress; true XL interior; 35 lb rating; folds flat to store; easy to clean.
Cons: No top door, so vet exams mean coming out of the side; its size means you should check it fits your car seat or footwell.
Best for: Most large cats and their owners — the default recommendation, especially for cats that hate front-loading carriers.
2. Petmate Two-Door Top Load Kennel, 24 in — Best Top-Loader for Vet Visits
Petmate Two-Door Top Load Kennel
If vet trips are your main journey, a top-loading kennel changes everything: you lift the cat up and lower them in — gravity on your side — and at the clinic the vet can lift the lid and examine a nervous cat while it stays in the base. This Petmate has both a steel top door and a steel front door with easy-squeeze latches, measures 24.05 x 16.8 x 14.5 in, and is made in the USA. The shell is sturdy plastic with ventilation on all sides and a “stay-dry” moat that channels any accidents away from your cat.
Petmate states this 24 in size suits pets up to 15 lb, so it fits the larger end of average and moderately big cats rather than giant breeds. The listing also says it meets most airline cargo specifications — check with your airline, as always.
Pros: Top and front steel doors; easiest design for vet handling; solid, easy-clean shell; fold-down handle; made in the USA.
Cons: The 15 lb limit rules out the biggest cats; requires simple wingnut-and-bolt assembly out of the box.
Best for: Cats up to about 15 lb whose owners want the least stressful vet-visit loading and unloading.
3. Sherpa Original Deluxe, Large — Best Soft Carrier for Travel
Sherpa essentially invented the in-cabin pet carrier, and the Large Original Deluxe is the biggest of the line: 19 x 11.75 x 11.5 in, for pets up to 22 lb and up to about 18 in long and 11 in tall. It loads from the top or the side, has locking zippers, mesh panels on all sides, a seatbelt/luggage strap and a machine-washable faux lambskin liner. A patented spring wire frame lets the rear flex down slightly to fit under airline seats.
On flying, be precise: Sherpa’s listing describes the carrier as approved for use on most major airlines, but its “Guaranteed On Board” programme covers only the small and medium sizes — so for the Large, always confirm your airline’s current cabin dimensions and weight limit before you rely on it. For car journeys, though, no such caveats apply, and the padded shoulder strap makes carrying a heavy cat kinder on you.
Pros: Biggest reputable soft carrier; top and side entry; locking zippers; washable liner; seatbelt strap for car travel.
Cons: Soft walls give a determined cat something to push against; designed for a lying-down pet, so tall cats can’t fully stand; airline acceptance is not guaranteed for this size.
Best for: Large cats up to 22 lb for car trips and — airline permitting — cabin travel.
4. Petseek Extra Large Cat Carrier with Wheels — Biggest Soft Option
Petseek Extra Large Cat Carrier
When even “large” carriers come up short, this is the step up: 24 x 16.5 x 16 in of space, rated by Petseek for pets up to 44 lb — enough for the biggest single cat, or two medium cats on the same trip. Crucially for a soft carrier, it has an internal metal support structure, so the roof and floor keep their shape under a heavy cat instead of sagging around them. Detachable wheels take the weight off your shoulder, every zip has a lock, there are seatbelt loops for the car, and mesh windows on five sides keep air moving.
One honest flag from Petseek’s own listing: it states plainly that this carrier is not applicable to airlines — this is a car-and-vet carrier, not a cabin bag. At roughly 14 lb before the cat goes in, it is also a piece of luggage in its own right; the wheels earn their keep.
Pros: Largest soft interior here; framed, non-sagging structure; wheels for heavy cats; locking zips and seatbelt loops; folds for storage.
Cons: Not for air travel; heavy to lift into a car despite the wheels; far too big to be a cosy den for smaller cats.
Best for: Very large cats, bonded pairs travelling by car, house moves and long drives.
5. Petmate Sky Kennel, 28 in — Best Heavy-Duty and Air Cargo Pick
The Sky Kennel is the traditional heavy-duty travel kennel, built for pets of 15-30 lb and sold for decades. The 28 in size measures 28 x 20.5 x 21.5 in outside, with a listed interior of roughly 24.25 x 18.25 x 19.5 in — lofty, stand-up headroom that big cats appreciate. It has a secure squeeze-latch steel door, 360-degree ventilation, and comes with clip-on water bowls plus “Live Animal” and ID stickers, because it is designed with airline cargo requirements in mind; Petmate lists it as airline compliant (confirm your airline’s rules, which change).
For everyday use, its virtues are strength and space: heavy plastic walls, plastic-covered hardware and an interior a large cat can properly stand and turn in. Its limitation is access — it is front-loading only, so a cat that refuses to enter may need the roof unbolted and lifted off, or a towel-and-patience approach.
Pros: Toughest build here; generous stand-up interior; airline-cargo oriented design with bowls and stickers included; made in the USA.
Cons: No top door for loading or vet exams; bulky to store and carry; more kennel than cosy carrier.
Best for: The biggest, strongest cats; cargo air travel; and households wanting one indestructible carrier for everything.
Hard-Sided vs Soft-Sided: Which Suits a Large Cat?
Hard-sided carriers (SportPet, both Petmates) protect the cat from knocks, stack safely in a car boot, hold their shape around a heavy animal and hose clean after accidents. They are the safer default for strong cats and for any cargo travel. Soft-sided carriers (Sherpa, Petseek) are lighter, squeezable into footwells, and usually pleasanter to carry over your shoulder — but only framed models like the Petseek avoid the sag-and-roll problem with a heavy cat, and none matches a hard shell for escape resistance. If your cat has ever burst a zip or chewed mesh, buy hard-sided.
Carrier Training and Travel Safety
- Make the carrier furniture, not an omen: Leave it out at home with the door open and a familiar blanket inside. Feed treats — then meals — inside it for a week or two before any trip. A carrier that only appears on vet day will always mean a fight, whatever size it is.
- Practise in stages: Door closed for a minute, then a lift, then a sit in the car, then a two-minute drive. Keep each step boring. A pheromone spray designed for cat carriers, used as its label directs about 15 minutes before travel, helps many cats.
- Load kindly: Use the top door, the wide side door, or place the carrier on end and lower the cat in backwards, rump first. Never tip and shake a reluctant cat out at the other end — ask the vet to work around the carrier’s base instead.
- In the car: Belt the carrier in or wedge it on the floor behind a seat so it can’t slide. Never leave a cat in a parked car in warm weather — interiors heat dangerously within minutes.
- When to talk to the vet: If your cat panics despite training — panting, drooling, toileting, frantic escape attempts — ask your vet about short-term anti-anxiety options for travel days. And any large cat that suddenly becomes hard to handle, vocal or off its food around trips may be in pain (arthritis is common in big, older cats); that’s a check-up, not a behaviour problem.
Frequently Asked Questions
How do I measure my cat for a carrier?
Measure length from the tip of the nose to the base of the tail, and height from the floor to the top of the head. The carrier interior should exceed the length measurement by at least a couple of inches, with height enough to stand without crouching. Then check your cat’s weight against the carrier’s rating and leave headroom.
My cat weighs 18 lb. Which of these fits?
The Petmate Two-Door tops out at 15 lb, so skip it. The Sherpa Large (up to 22 lb) works if your cat is under about 18 in long; the SportPet XL and Petmate Sky Kennel both fit comfortably, and the Petseek is the roomiest of all.
Can a large cat fly in the cabin?
Sometimes — it depends on the airline’s under-seat dimensions and weight limit, which vary and change. The Sherpa Large is the only pick here designed for cabin use, and even then its listing’s on-board guarantee covers the smaller sizes. Many cats over about 18-20 lb will exceed cabin limits and must travel as cargo in a kennel like the Sky Kennel, or by car.
Can two cats share the Petseek extra-large carrier?
Petseek rates it for up to 44 lb, so two medium cats fit physically. Sharing suits bonded pairs for short car trips, but separate carriers are usually calmer for vet visits — a stressed cat can redirect onto its companion, and the vet needs them one at a time anyway.
Why does my big cat hate the carrier so much?
Often because of history (it predicts the vet) and because old carriers were a squeeze. A correctly sized carrier, left out at home and used for treat-feeding and short practice trips, genuinely retrains most cats. If terror persists, speak to your vet about travel-day anxiety help rather than forcing it.
Our Verdict
For most people owned by a large cat, the SportPet Designs XL is the buy: a genuinely big interior, a 35 lb rating, and a walk-in door that defuses the dreaded loading battle. Choose the Petmate Two-Door if vet visits dominate and your cat is under 15 lb, the Sherpa Large for car travel and possible cabin flights up to 22 lb, the Petseek for the very largest cats or pairs by car, and the Sky Kennel when you need cargo-grade toughness. Whichever you choose, measure your cat first — in carriers, an inch is the difference between a den and a trap.
