Most cat owners only think about their carrier twice a year — right before a vet visit — but the right carrier can mean the difference between a calm cat and a panicked struggle. Stress during transport is one of the most common reasons cats miss veterinary appointments, according to a 2015 Bayer Veterinary Care Usage Study. This guide covers the three main carrier types, what to look for in each, and which specific models rise to the top in 2026.
Hard Plastic (Kennel-Style) Carriers: The classic design with a top and bottom shell that snap together, plus a metal wire door. These are durable, easy to disinfect, and widely accepted by airlines. Top-loading models (where the entire top half removes) make it much easier to place a reluctant cat inside.
Soft-Sided Carriers: Made from fabric over a wire or plastic frame. These are lighter than hard carriers, often more comfortable for the cat, and tend to work better for in-cabin airline travel because they can compress slightly under the seat. The downside: they're harder to clean thoroughly after an accident and less secure against determined escape artists.
Backpack Carriers: Worn like a backpack, these have gained popularity for cats that enjoy outdoor exposure. Most feature a bubble window or mesh panel. They're not appropriate for all cats — only confident, well-socialized cats should use them — and they are generally not airline-compliant.

The SportPet Designs Foldable Plastic Carrier addresses two common frustrations with traditional kennels: top-loading access and storage bulk. The entire top half opens, making it significantly easier to place a cat inside — no more shoving a resistant cat through a small front door. When not in use, the carrier folds flat to about 4 inches thick.
It's made from heavy-duty plastic with a steel wire door and comes in multiple sizes. The smaller size (19-inch) is suitable for cats up to about 12 pounds; larger cats or those that prefer more space should opt for the 24-inch version. Ventilation is provided by side slits and the wire front door. Note that this carrier is designed for car travel and vet visits — for air cargo travel, you'll need an IATA-compliant option like the Petmate Sky Kennel.

Sherpa's "Guaranteed On-Board" program means the company will refund your carrier purchase if you're denied boarding while using one of their carriers — though you should always verify your specific airline's pet policy before travel, as rules change frequently.
The carrier features mesh panels on three sides for ventilation, a spring-wire frame that allows it to flex under an airplane seat but bounce back to shape, and a locking zipper system that prevents cats from pushing the zipper open from the inside. A removable, machine-washable faux lambskin liner provides cushioning. The medium size (17 x 11 x 10.5 inches) fits under most airline seats.

One or both sides unzip to reveal mesh-paneled extensions that nearly double the interior space. This is particularly useful for longer car trips or for cats who get anxious in confined spaces. When fully expanded, the carrier can double as a temporary playpen at a destination.
The carrier includes a removable fleece pad, a shoulder strap, and carry handles. Mesh panels on all sides (including the top) provide excellent ventilation. Three entry points — top, front, and side — make it easy to access your cat from whatever angle works best.
Check Price on AmazonThe PetAmi Deluxe Backpack represents the popular bubble-window style that lets a cat look out during walks. It includes a safety tether that clips to a harness (never a collar) to prevent bolting, plus mesh panels for airflow. The backpack is well-ventilated, but on hot days a backpack can become an oven — limit outdoor use to temperatures under 75°F and avoid direct sun on the bubble window, which creates a greenhouse effect.
Backpack carriers are best suited for cats that are confident, curious, and already comfortable in carriers. A shy or anxious cat will likely find the experience stressful rather than enriching. Start with short sessions indoors and work up to outdoor walks only if your cat shows relaxed body language throughout.
Check Price on AmazonMany cats associate the carrier only with vet visits, which creates a negative emotional response. You can recondition this by keeping the carrier out permanently — in a quiet corner, with the door removed or propped open, and a soft bed inside. Tossing treats or sprinkling catnip in the carrier periodically encourages positive exploration.
When you do need to transport your cat, spraying the carrier with a synthetic feline facial pheromone product such as Feliway approximately 15 minutes before loading has been shown in multiple studies to reduce stress behaviors during transport. Bring a familiar-smelling towel from home and, for longer trips, a small portable litter box.
