Large cats complicate both halves of this keyword. ‘Machine washable’ needs the usual honesty — no hard kennel goes in a washing machine, so the real answers are whole-unit washable (SturdiBag), removable pads and bedding (Amazon Basics, Sleepypod), and washable liners and covers (Sherpa, Jespet, EliteField). And ‘airline’ for a large cat needs honesty too: most in-cabin limits cap around 18-20 pounds, so a genuinely large cat often flies cargo or travels by car — and the picks below cover both realities.
Every product here is labeled with exactly what washes and how, plus its real capacity. A 20-pound Maine Coon needs an 18-to-20-inch carrier minimum; anything smaller is a kitten product regardless of what the title says.
The excluded list matters: hard shells (wipe-down only) and spot-clean-only soft carriers don’t appear, no matter how popular. What remains is the genuinely washable shortlist for big cats that travel.

1. SturdiBag Large Pet Carrier — Best Machine Washable
Whole-unit machine washable per care instructions, flex-height for under-seat fit, rated to ~30 pounds — the complete answer for this keyword. The SturdiBag Large (18 x 12 x 12 inches, 2.9 pounds, tested to about 30 pounds) is the flexible-height carrier: support rods create a dome that compresses under an airline seat, then pops back up — the closest thing to an ‘adjustable’ carrier in the classic sense. Care instructions say machine washable, the fleece comfort pad washes too, and seatbelt straps plus safety clips handle the car leg.
It’s genuinely one of the only carriers on this page the whole unit can go in the washing machine — the copy says so because the manufacturer does. Downsides: the dome needs the rods installed to hold shape, and it’s a soft carrier, so no crash-test claims. For large cats and small-medium dogs, it’s the washable, flexible, flyable all-rounder.
Specs: 18 x 12 x 12 in · ~2.9 lbs · tested to ~30 lbs · flex-height dome · care: machine washable · seatbelt straps · privacy flaps.
Pros: Machine washable per care instructions; flex-height for under-seat fit; very light; roomy.
Cons: Rods needed for structure; not crash-tested; soft-sided only.
Verdict: The washable, flexible-height all-rounder for cats and small dogs. Check the price on Amazon
2. Sleepypod Air In-Cabin Pet Carrier — Best Premium Washable
Machine-washable bedding, crash-tested engineering, expands in flight — the premium large-cat carrier that earns its price. The Sleepypod Air (22 x 10.5 x 10.5 inches, 4.5 pounds, pets to 18 pounds) is the engineering answer to in-cabin travel: a patented folding design that compresses to fit under an airline seat for takeoff and landing, then expands between your feet in flight so the animal gets maximum room. Straps on both sides secure it in a car, and the plush bedding is machine washable. Sleepypod is one of the only brands that crash-tests its carriers, and the Air is sold as a crash-tested model.
The honest limits: 18 pounds max rules out medium dogs entirely, and the premium price is several times a basic carrier. But for a cat or small dog, this is the rare product that is simultaneously airline-smart, car-smart (straps), crash-tested, and machine-washable where it counts — the bedding.
Specs: 22 x 10.5 x 10.5 in · 4.5 lbs · pets to 18 lbs · expands in flight / compresses under seat · car straps · machine-washable bedding · crash-tested.
Pros: Crash-tested; expandable in-cabin design; machine-washable bedding; car straps included.
Cons: 18-lb limit; premium price; overkill for ground-only travel.
Verdict: The premium small-pet carrier — crash-tested and genuinely airline-smart. Check the price on Amazon
3. Amazon Basics Soft-Sided Mesh Carrier — Best Budget Washable
The budget carrier with a removable machine-washable fleece pad and 22-pound capacity — the value way to keep a big cat’s den clean. The Amazon Basics soft-sided mesh carrier (20 x 12 x 12 inches, 2.9 pounds, pets to 22 pounds) is the value in-cabin soft carrier: front and top zippered openings, mesh ventilation panels, connecting top handles, adjustable shoulder strap, leash clip — and the cleaning story that matters here, a removable fleece pad that is machine washable (wash separately in cool water, line dry).
Only the pad goes in the machine — the shell is spot-clean — and the copy says exactly that. No crash-test data either. But for a 22-pound-capacity, under-seat-conforming soft carrier with a washable pad at a budget price, this is the value pick that makes the expensive options justify themselves.
Specs: 20 x 12 x 12 in · pets to 22 lbs · ~2.9 lbs · front + top zips · removable machine-washable fleece pad · under-seat conforming.
Pros: Machine-washable pad; 22-lb capacity; very light; budget price.
Cons: Shell spot-clean only; not crash-tested; basic zippers.
Verdict: The value soft carrier — washable pad and 22-lb capacity for less. Check the price on Amazon
4. Sherpa Original Deluxe Pet Carrier, Medium — Best Washable Liner
The premium classic: removable machine-washable liner, top-and-side entry for easy loading, boarding guarantee. The Sherpa Original Deluxe Medium (17 x 11 x 10.5 inches, 3.5 pounds, pets to 16 pounds) scales the Sherpa formula to cats and small dogs: spring-wire frame that compresses for under-seat fit, mesh panels with privacy flaps, locking zippers, top and side entry, a large side pocket, and the removable machine-washable faux-lambskin liner. It’s included in the Guaranteed On Board program.
Top-and-side entry is the senior-cat-friendly detail — no high front lip to climb over — though 16 pounds is the ceiling and the shell itself is spot-clean only. For a senior small dog or cat flying in-cabin, the low-stress loading and washable liner are the right combination.
Specs: 17 x 11 x 10.5 in · pets to 16 lbs · top + side entry · spring-wire frame · removable machine-washable liner · Guaranteed On Board.
Pros: Low-stress top/side entry; washable liner; boarding guarantee; light.
Cons: 16-lb limit; shell spot-clean only; premium price for the size.
Verdict: The senior-friendly premium carrier — easy entry and a washable liner. Check the price on Amazon
5. Jespet 36-Inch Soft Dog Crate — Best Crate Format
For car travel: a 36-inch folding soft crate with washable fabric — a traveling territory, not just a carrier. The Jespet 36 (36 x 24 x 27 inches, dogs to 70 pounds) is a folding soft crate with a steel-tube frame, three mesh doors (top, front, side), 600D cationic oxford fabric the brand describes as washable, and a fleece mat in the box. At about 10.5 pounds it’s a fraction of a hard kennel’s weight, and it folds flat for storage — the combination that makes soft crates the travel choice for calm, crate-trained dogs.
Soft crates are not for chewers, diggers, or escape artists — the brand is clear about that, and so are we. There’s also no crash-test data; a soft crate is containment, not a crash cell. For the right dog, though, the washable fabric and featherweight foldability are exactly what road-trip life needs.
Specs: 36 x 24 x 27 in · dogs to 70 lbs · steel tube frame · 3 mesh doors · washable 600D fabric · fleece mat · ~10.5 lbs.
Pros: Featherweight vs hard kennels; washable fabric; 3 doors; folds flat.
Cons: Not for chewers/escape artists; not crash-tested; less secure than hard shell.
Verdict: The lightweight folding crate for calm, crate-trained travelers. Check the price on Amazon
6. EliteField 3-Door Folding Soft Dog Crate, 36-Inch — Best Premium Crate
Crate cover and bed cover both remove and wash, 2-year warranty — the nicest soft-crate cleaning story for big cats that drive. EliteField’s 36-inch soft crate (36 x 24 x 28 inches) is the premium end of the soft-crate class: steel-tube frame, 600D fabric with hex mesh, three zippered doors with locks, two accessory pockets, a free carrying bag, a fleece bed — and, critically for cleaning, a crate cover and bed cover that are both removable and washable. A 2-year warranty backs it.
The honest framing stands: soft, so not for destructive dogs, and not crash-tested — no soft crate on this page is. But if you want the nicest-feeling folding travel crate with genuinely easy cleaning, the removable washable covers make EliteField the pick over cheaper soft crates.
Specs: 36 x 24 x 28 in · steel frame · 3 locking mesh doors · removable washable cover + bed cover · carrying bag · 2-year warranty.
Pros: Removable washable covers; premium materials; warranty; complete accessory set.
Cons: Not for chewers; not crash-tested; pricier than basic soft crates.
Verdict: The premium soft crate — washable covers and a warranty to match. Check the price on Amazon
How to Choose a Machine-Washable Airline Kennel for a Large Cat
Check the airline’s weight limit before the carrier’s. Most in-cabin programs cap at 18-20 pounds including the carrier. A large cat over that flies cargo (hard kennel rules) or drives — buy for the actual trip, not the keyword.
Whole-unit washable is the gold standard. The SturdiBag’s care label covers the carrier itself. Everything else washes a component — pad, bedding, liner, cover — which is still the practical answer, since that’s what the cat soils.
For car travel, think crate, not carrier. A 36-inch folding soft crate gives a large cat room, a litter corner on long drives, and folds flat at the hotel. Carriers are for flights; crates are for road trips.
Top entry saves the struggle. Loading a 18-pound cat through a front door is a wrestling match. Top-and-side entry (Sherpa Medium) or wide top zips (Amazon Basics mesh) change the experience completely.
Wash the bedding, wipe the shell. Machine wash removable fabric cool and line dry; spot-clean shells with soapy water; enzyme-treat urine odor rather than perfuming it. That’s the whole cleaning playbook.
Keep a spare pad. One accident mid-trip shouldn’t end hygiene. A second washable pad or liner is the cheapest travel upgrade there is.
Frequently Asked Questions
Can a large cat fly in the cabin?
Usually only if cat plus carrier stay under the airline’s limit (typically 18-20 lbs total) and the carrier fits under the seat. Larger cats generally fly as cargo or travel by car — check your airline’s published rules.
Is the SturdiBag really fully machine washable?
Per the manufacturer’s care instructions, yes — the carrier and the fleece pad. It’s the standout washable claim in this category.
What’s the best carrier size for a Maine Coon?
18-20 inches minimum for a carrier, or a 36-inch soft crate for car travel. Measure the cat: body length plus room to turn around comfortably.
How do I get cat urine smell out of a carrier?
Machine wash what removes (pads, liners, covers); enzyme cleaner on what doesn’t. Soap and fragrance just mask it — enzymes break it down.
Are hard carriers better for large cats?
They’re sturdier and hose down easily, but they’re not machine washable and they’re heavy. For flights, soft is standard; for cargo, hard is required.
The Bottom Line
The complete answer is the SturdiBag Large — machine washable as a whole unit, flex-height for under-seat fit, and rated for big cats. The Sleepypod Air is the premium crash-tested alternative, the Amazon Basics Mesh is the budget washable-pad pick, and the EliteField 36 is the road-trip crate with truly removable washable covers.
