In-depth carrier reviews
Sherpa Original Deluxe Travel Pet Carrier Medium
The Sherpa Original Deluxe Medium is one of the most recognized soft-sided airline carriers on the market. Its patented spring-wire frame collapses slightly under pressure, helping it squeeze under seats that have limited clearance. The carrier offers both a top and a side-entry door, mesh ventilation panels on multiple sides, and a faux lambskin liner for comfort. Multiple interior attachment points keep your pet secure. The Guaranteed On Board program provides reassurance when flying with major US airlines.
Pros
- Airline-approved by most major carriers
- Collapsible spring-wire frame for under-seat fit
- Top and side-entry doors
- Comfortable faux lambskin liner
Cons
- No rigid structure, so not ideal if your pet pushes against sides aggressively
- The Guaranteed On Board program has eligibility conditions
Sherpa Original Deluxe Travel Pet Carrier Large
The large version of the Sherpa Original Deluxe is designed for pets up to 22 pounds and offers the same core features as the medium: collapsible frame, dual entry doors, and mesh ventilation. At 19 inches long by 11.75 inches wide by 11.5 inches tall, it is typically too large for under-seat cabin storage but works well for cargo hold check-in or road trips where size is not restricted. Useful for owners with multiple cats or a larger small-breed dog.
Pros
- Fits pets up to 22 lbs
- Same quality construction as the medium
- Good ventilation on all sides
- Suitable for car travel and cargo check-in
Cons
- Generally too large for most airline under-seat dimensions
- Heavier than the medium version
Petmate Two Door Deluxe Cat Carrier Small
The Petmate Two Door Deluxe is a lightweight plastic carrier with two opening methods: a conventional front door and a top-load door that makes it easier to place a reluctant cat inside without a struggle. The construction is durable hard-sided plastic, which provides more structural protection than fabric carriers and is easier to clean after accidents. It is a practical, affordable choice for routine vet visits or short car trips.
Pros
- Top-load and front-door access
- Hard plastic is easy to clean
- Affordable entry-level option
- Good ventilation through door grates
Cons
- Not airline-approved for cabin use
- Less comfortable for long journeys than padded soft carriers
Petmate Two Door Deluxe Kennel Intermediate
The Petmate Two Door Deluxe Kennel in the intermediate size is a solid hard-sided crate for medium-small dogs or multiple cats. Two door access points and a secure latch system make loading and unloading straightforward. The plastic construction withstands repeated cleaning and does not absorb odors. It is a reliable choice for vet visits, road travel, and keeping at home as a familiar safe space for your pet.
Pros
- Two door access for easy loading
- Durable hard-sided construction
- Easy to disassemble and clean
- Works as a home crate too
Cons
- Bulkier to store than soft carriers
- No padding included
What to look for in a pet carrier
The right carrier depends primarily on how you plan to use it. For air travel, an airline-approved soft carrier with the right dimensions is essential. For vet visits or road trips, a sturdy hard-sided carrier can be easier to clean and more protective. Always check that your pet can stand, turn around, and lie down comfortably inside before purchasing.
FAQ
What size carrier do I need for my cat?
Most adult cats fit comfortably in a small to medium carrier. As a general rule, your cat should be able to stand, turn around, and lie down without restriction. Measure your cat from nose to tail and add a few inches.
Are soft or hard pet carriers better for airline travel?
Soft carriers are generally preferred for in-cabin travel because they compress slightly to fit under the seat. Hard-sided carriers are typically used for cargo hold travel, where structural protection is more important.
Can I use a dog carrier for a cat?
Yes, as long as the dimensions are appropriate and the carrier is secure. Most carriers labeled for dogs or cats are interchangeable by size. Focus on weight capacity and interior dimensions rather than the label.
How do I get my cat or dog used to a new carrier?
Leave the carrier open at home with a familiar blanket or toy inside. Let your pet explore it at their own pace over several days before any travel. Short positive practice trips help build comfort.
