Best Cat Carriers for Large Cats (2026)

Every mainstream cat carrier publishes a pet weight limit, and almost all of them stop below twenty pounds. That is the finding, and it decides the shortlist.

Ferplast Atlas 20 Deluxe Open

Everyone in this category says they tested twenty litter boxes. We have not tested any, and we say so. What we do instead: compile the published specs, read the manuals, and do the arithmetic on what this gear costs to run and how it behaves once there is more than one cat using it. Every spec is linked to the document it came from. Prices are checked daily — last verified October 19, 2026. Here is exactly how we pick.

Buy the Ferplast Atlas 20 Deluxe Open for a large cat: a published 8 kg (about 17.6 lb) limit, roughly 22.4 by 14.6 by 13 inches outside, and a roof that opens across its full width so you can lower a heavy cat in rather than wrestle it through a door. If your cat is over about 18 lb, no mainstream cat carrier publishes a limit that covers it — and the honest alternatives are a soft double carrier used as one big compartment, or a dog crate.

The category has a ceiling, and it is published

The site has large-cat pages for litter boxes, automatic litter boxes, cat trees and scratching posts, and until now not for carriers. Researching it produced a blunter answer than expected.

The arithmetic — Published pet weight limits across the carriers on this site

Petmate Two Door 19 inch: up to 10 lb.

Ferplast Atlas 20 Deluxe Open: up to 8 kg, about 17.6 lb.

Sleepypod Air: 18 lb maximum pet weight.

Petskd double carrier: 80 lb total, per the listing — but that is a two-compartment soft carrier, not a conventional one.

So the mainstream category effectively stops at 17 to 18 lb. A Maine Coon, a large domestic shorthair or any cat around twenty pounds is outside the stated limit of every normal carrier on the market — and the most common carrier shape in the shop, the 19 inch hard kennel, publishes a limit of ten pounds.

That is worth sitting with, because the usual advice for a big cat is “buy a bigger carrier”, and bigger carriers mostly do not exist in the cat aisle. They exist in the dog aisle.

For a large cat, buy the Ferplast Atlas 20 Deluxe Open — published to 8 kg (about 17.6 lb), about 22.4 x 14.6 x 13 inches, with a full-width opening roof so a heavy cat can be lowered in. Be aware the whole category has a ceiling: Petmate publishes 10 lb on its 19 inch kennel, Ferplast 17.6 lb, Sleepypod 18 lb. Above about 18 lb, use a soft double carrier as one compartment (80 lb total published, each half 18 x 17 x 17 in) or a dog crate.

Manufacturers' and retailers' published figures as named in our sources. Ferplast publishes no interior dimension, which for a large cat is the figure you most want and cannot get.

The gap in the Ferplast sheet. It publishes a confident external size and a weight limit, and no interior dimension at all. For a large cat that is the specification that decides everything — whether it can stand, turn around and lie down — and a 22.4 inch exterior in hard plastic with grills does not tell you what is inside it. Our carrier sizing guide works the problem from the cat’s measurements for exactly this reason.

Why top loading matters more as the cat gets bigger

A six-pound cat can be posted through a front door by one person. A seventeen-pound cat cannot: it braces against the opening, you are lifting its full weight at arm’s length, and the usual outcome is a scratched forearm and a cat under the bed for the rest of the day.

Lowering the same cat straight down through an open roof takes seconds and no negotiation, because a cat that is already being held does not have a doorway to brace against. That is why the Atlas 20’s full-width opening roof leads this page over carriers with better crash credentials. Our getting a cat into a carrier guide covers the technique, and top-loading carriers ranks the format on published opening area.

The picks, and who each is for

The Ferplast Atlas 20 Deluxe Open is the pick for most large cats. It publishes the highest weight limit of any conventional hard carrier here at 8 kg, roughly 22.4 by 14.6 by 13 inches externally in recycled hard plastic, with a plastic-coated steel grid roof that opens across the full width plus a front door, side-wall ventilation grills, and a washable cotton cushion and feeder included. For: cats up to about 17 lb, vet trips, and anyone who has ever failed to get a big cat through a front door. Skip it if: your cat is over 17.6 lb — Ferplast has drawn that line itself — or you need a published interior dimension or a crash rating, neither of which exists for this carrier.

The Petskd double carrier is the pick for a cat the rest of the category has excluded, used as one large compartment rather than as two. The listing publishes 80 lb total with each half at 18 by 17 by 17 inches — and the arithmetic is the argument: one half is about 5,202 cubic inches against roughly 1,705 in a standard 19 inch kennel, so about three times the room. It zips apart, includes a litter box and locking zippers, and is soft-sided so it packs down. For: cats over 18 lb, long car journeys, two cats traveling together. Skip it if: safety certification is your criterion — no crash testing is published — or you need something rigid and one-hand carryable to a vet.

The Sleepypod Air is the pick when the cat is near but under 18 lb and crash protection is the reason you are buying. It is the only carrier here with an independent crash rating attached to a published weight — Sleepypod publishes 18 lb — and the only one that publishes an interior at all: 15 to 21 inches long by 9.5 by 9.5, compressing from 22 inches to 16 for an under-seat space. For: a large-ish cat in a car, and flights. Skip it if: the cat is over 18 lb, or broad rather than long — 9.5 inches of width and height is the real constraint on a heavy cat, and it is a front-loader, which is the hard way to load one.

If your cat is over 18 pounds

  • Accept that you are off the cat-carrier map. No mainstream cat carrier publishes a limit above 18 lb. Pretending otherwise is how a carrier fails on the way to the vet.
  • Use the double carrier as a single. Three times the interior volume, and the cat travels in one compartment with room to lie flat.
  • Or buy a dog crate sized to the cat. Less convenient, properly rated, and the option vets themselves tend to suggest for very large cats.
  • Measure rather than guess. Nose to base of tail standing, and floor to shoulder. Interior length should exceed the first figure.
  • Weight that is new is a vet question. A cat that has recently become large is a different conversation from a cat that is built large, and the Cornell Feline Health Center is the place to start it.

Our arithmetic — Opening area against a front door
The whole footprint, not a hatch

The Atlas opens along the full length of the roof, so the opening is close to the carrier's own 22.4 by 14.6 inch footprint. A front door is a hole roughly 10 inches square that a cat has to be posted through lengthways. That is the difference between lowering a cat in and pushing one in.

What the specs favor

  • Full-width opening roof rather than a small top hatch
  • Published weight limit and external dimensions
  • Grid roof means the cat can see out and be seen on the way to the vet
  • Feeder and washable cushion included

What they don't

  • Interior dimensions are not published, only the exterior
  • No published safety or crash testing
  • Plastic clips around the rim wear with heavy use
  • 8 kg is a modest ceiling for a very large cat
Skip this one if

Your cat weighs more than about 17 lb. Ferplast publishes 8 kg, and a carrier used beyond its stated limit is a carrier you cannot rely on.

Our arithmetic — Each half against a standard carrier
5,202 cu in vs 1,705 cu in

18 x 17 x 17 = 5,202 cubic inches per half, about three times the Petmate 19 inch kennel's 1,705 of interior. That room is the point on a long drive with a litter box inside -- and it is far too big for an under-seat space or a quick vet visit.

What the specs favor

  • Each cat has its own compartment
  • Room for a litter box on a long drive
  • Halves can be used separately
  • Locking zippers

What they don't

  • No published crash testing
  • Far too large for an aircraft cabin
  • Soft sides offer little protection in a collision
Skip this one if

The journey is a vet visit. Two separate hard carriers are easier to handle, to clean and to carry one at a time.

Our arithmetic — Interior length lost when compressed
6 inches, or 29 percent

Interior runs 15 to 21 inches. Compressing to fit an under-seat space removes 6 of 21 inches, 29 percent of the cat's floor length. A cat that is comfortable at 21 inches is folded at 15 -- so compress it on the aircraft, not for the whole trip.

What the specs favor

  • Independent crash certification tied to a published weight limit
  • Interior dimensions published, not just exterior
  • Mesh on four sides, which is what international carriage rules tend to ask for
  • Washable bedding included rather than sold separately

What they don't

  • 18 lb published ceiling rules out large breeds
  • 4.5 lb empty is heavy before the cat goes in
  • Compressed length is a real reduction in the cat's space, not a design trick
Skip this one if

Your cat is over 18 lb. That figure is both the manufacturer's limit and the boundary of the crash certification, so exceeding it discards the main reason to buy this carrier.

Common questions

What carrier should I buy for a large cat?
The Ferplast Atlas 20 Deluxe Open for most large cats: it publishes a pet weight limit of 8 kg (about 17.6 lb), measures about 22.4 by 14.6 by 13 inches externally, and its entire roof opens so you can lower a big cat in from above rather than pushing it through a door. For a cat over about 18 lb, the honest answer is a soft double carrier used as a single, or a dog crate.
What is the weight limit on a cat carrier?
Lower than most people expect, and it is published. Petmate states up to 10 lb on its 19 inch two-door kennel, Ferplast states 8 kg (17.6 lb) on the Atlas 20, and Sleepypod states 18 lb on the Air. So the mainstream category effectively stops at 17 to 18 lb -- which means a 20 lb Maine Coon is outside every one of those stated limits.
What carrier works for a 20 pound cat?
Not a standard cat carrier, on published figures. The two honest routes are a soft double carrier used as a single compartment -- the Petskd publishes 80 lb total with each half at 18 by 17 by 17 inches, which is three times the interior volume of a standard carrier -- or a hard dog crate sized to the cat. Both trade portability for room.
Does a large cat need a top-loading carrier?
It helps more than it does for a small cat. Pushing a 17 lb cat through a front door is a two-person job and usually a failed one; lowering it in through an opening roof is one person and a few seconds. The Ferplast Atlas 20's full-width opening roof is the reason it leads this page.
How do I measure my cat for a carrier?
Measure nose to base of tail while standing, and floor to shoulder. The carrier interior needs to let the cat stand, turn around and lie down -- so interior length should exceed the nose-to-tail figure, not match it. Our carrier sizing guide works through that against published interiors, which is the figure most makers withhold.
