Best Cat Carriers with a Litter Box of 2026

Twenty inches long and fourteen wide is about the footprint of a weekender bag, which is why this is the carrier that fits a compact's passenger seat or the gap between two child seats. The feature doing the work is a zip-out bay at one end: open it and you gain 16.5 by 12 by 12 inches, enough for the included 15-by-11.5-inch litter box to sit in its own compartment instead of on top of your cat.

That arrangement is what we like most about it. The tray has a lid and a leakproof base, so it travels without shedding litter into the cabin, and the main box stays a cat-shaped space rather than a box-shaped one. pidipiti rates it for one medium cat up to 15 pounds with the tray inside, or a large cat up to 20 pounds with the tray left at home, and that's honest. This is not the carrier to buy for a pair.

Elsewhere the details are the ones we look for on a much bigger budget: locking double zippers on every opening, anti-scratch mesh, an adjustable tether inside, three pockets, and metal hooks where the shoulder strap meets the bag instead of plastic. At 5.7 pounds empty it's the lightest full-featured option here, and it folds flat enough to slide into a drawer.

Its smaller sibling puts the litter box in the expansion; this one does the opposite, and we think that's the better call for a big cat. The 16-by-13-by-12-inch tray sits in the main cabin with sides tall enough to keep litter in, and the zip-out panel supplies the extra space instead, so the cat gains room and the box doesn't steal it.

The figures back that up: one large cat up to 20 to 25 pounds with the box in place, or up to 35 pounds with the box left at home, which is also where two medium-large cats fit. Height is where most soft carriers fall short, and 17 inches lets a tall cat stand without crouching. You get the same locking zippers, anti-scratch mesh, and internal tether as the smaller model, plus a foldable food bowl and a shoulder strap that keeps the base flat when the carrier is loaded.

What we appreciate is that the pieces are sized to fit each other: the tray slides out for emptying without collapsing the carrier, the tether clips where a harness reaches, and the pockets take a scoop, a bag of litter, and a folded pad. For a cat who has outgrown a 14-inch carrier, the extra inches here are the ones that matter.

Zippers on both ends mean this isn't fixed at two cats: buy a second section and a third and they chain into one long cabin, which is the closest thing here to a carrier that grows with the household. A single unit is 38 by 17 by 18 inches, most of a back seat, and it's rated to 80 pounds in total.

What we like is that the extras assume a real trip rather than a vet visit: a lidded litter box, a bowl, a bag for food, a removable hammock, and a seatbelt buckle plus an inner safety strap. The lid is the detail that matters most, because a covered tray keeps litter in the car instead of in the footwell, and that's the difference between the box getting used and the floor getting cleaned around it.

A three-year warranty is longer than most of this group offers, and every panel locks. The section zip needs its two ends square before it will run, so join the pieces in the driveway rather than in a parking lot after you've loaded the cats.

The bones of this carrier are good: a foldable iron frame, Oxford cloth outside, nylon mesh that resists tearing, locking zippers on every opening, and a collapsible litter tray plus two bowls in the box. It's the same 24-by-16.5-by-16-inch format as our top pick, which is the right size for a large cat or a pair of medium ones.

Where it differs is the assembly. The top is held up by tension rods that have to be pulled fully into position; leave one partway and the roof sags into the space the cat needs, which is the kind of thing you notice on the second setup rather than the first. Once everything is seated, the frame keeps its shape even with a cat standing on top of it.

The kit is genuinely complete, tray, two bowls, and a fold-flat storage shape included, and there's enough length inside for a cat to stretch out full. It costs a little more than our top pick for the same footprint, so what you're buying is the frame and the matching set rather than extra room.

Our judgement is that it suits a calm traveler and tests a nervous one. The frame will outlast the material around it, so the stitching is what decides how many trips you get out of it, and a cat who treats mesh as a challenge will find the limits of a soft-sided crate faster here than in the top pick. For a cat who sleeps through a drive, that trade is easy to accept.

What arrives is a pop-up room, not a carrier in the usual sense. Opened out it measures 31.8 by 20 by 20 inches, enough for two cats, a litter box, and a bed, with roll-up mesh panels along the long sides, doors at the front and the side, and a double-sided waterproof fleece mat that lifts out for washing.

It folds to a 14-inch circle about 4.5 inches deep and comes with a storage bag big enough for the enclosure and the matching litter box, which is sold separately. If you already own a portable box, measure it against the 13.7-inch front opening before you count on fitting it inside.

Where this earns its place is the other end of the drive. Set up in a hotel room or a rental, it gives a cat somewhere familiar to eat, sleep, and toilet while the furniture stays unmarked, and the panels roll up so you can see what's going on without opening a door. Being soft-walled, it doesn't hold its shape while it's being moved and it's a two-person lift with a cat inside, so it's a room you set down rather than a bag you swing over your shoulder.

At 39.3 inches long, this is the only thing here that spans a whole back seat, and the two compartments are the reason: one half for sleeping, one for the litter box and bowls, or one open room once you unzip the divider between them. It goes up like a tent on glass rods with no assembly, and lifting the blue fabric reveals mesh windows for airflow and a view out.

The kit is thoughtful for what it is: a carry bag, two hammocks, mats, and a collapsible litter box, and the hammocks get used as shelves more than beds. Interior height means a cat can stand and turn in either half, which a 24-inch carrier can't offer once a tray is inside it.

The floor is what we noticed first. With a heavier cat moving between compartments the base shifts and the whole tent creeps, and a folded blanket or a rubber-backed mat underneath settles it, so sort that before a long drive rather than at the first rest stop. The hammocks sag under a big cat too, so treat them as a perch for a small one.

Rated to 15 kg, it's a room with a handle rather than something you'd carry far, and that's the trade we accept. It holds two cats and their litter for a day of driving, sets up in about a minute, and gives a cat somewhere to walk on the other end, which is closer to how cats live than a carrier usually gets.

Two cats who complain when they're separated but can't share one box have an unusual option here: two carriers that zip together along the middle, with a window between them that rolls up or down. Each half has its own door, its own mesh panels, and room for the included litter box and collapsible bowl.

The design earns its keep on the drive. Cats that travel better as a pair can see and smell each other without sitting in the same tray of litter, and the unit splits apart again for a solo appointment. It's rated for 35 pounds across both halves, and pipe connectors hold the shape when it's set up and let it break down flat when it isn't.

Where it wins us over is the long trip: a thousand miles of interstate is exactly the use case, and the mesh gives the cats something to watch instead of a wall of fabric. Locking zippers and reinforced stitching cover the escape routes, though a cat that claws at a corner can work the teeth apart, so check both ends of every zip before you load up.
