Are you trying to find a comfortable, portable crate that works for travel and everyday use with your cat, dog, rabbit, or other small animal?

First Impressions
Personal Anecdote: When I first started Amazon Basics 4-Doors Portable Soft-Sided Travel Crate Kennel review, I remember struggling with the basics. It took patience and a few mistakes to understand how to get it right.
When you first see the Amazon Basics 4-Doors Portable Soft-Sided Folding Travel Crate Kennel for cat, Dog, and Other Small Animals, Grey, M 30″ x 21″ x 21″, you’ll notice it’s compact and thoughtfully designed for convenience. The pop-up construction and soft sides make it clear this kennel is built for portability and short-term containment more than long-term heavy-duty use.
Product Overview
This medium 4-door folding pet travel kennel measures 30 x 21 x 21 inches (LxWxH) and comes with a removable fleece pet bed pad, carrying handle, padded shoulder strap, and straps to secure rolled-up doors. You’ll get a water-resistant base, a top door for ventilation and light, and front and side zippered doors with lock clips that add security when you need it.
What’s in the Box
You’ll receive the soft-sided kennel itself, a removable fleece pad, the padded shoulder strap, carry handle already attached, and straps to secure the fabric doors when opened. There are no tools required because the crate pops up and folds down using the built-in frame.
Design and Build Quality
You’ll appreciate that the kennel uses soft fabric panels on a collapsible frame, making the unit lightweight and easy to handle. The fabric and seams look adequate for general travel and temporary containment, though it’s not designed to withstand heavy chewing or determined escape attempts.
Materials and Durability
The outer fabric is water-resistant and the base is designed to resist seepage, which helps during outdoor use or accidental spills. For durability, the unit is best suited to calm to moderately active pets; very strong or persistent chewers may test the limits of the fabric and zippers over time.
Portability and Storage
You can fold the crate down in seconds into a flat bundle and use either the carry handle or padded shoulder strap to move it. If you travel frequently, you’ll find the small packed footprint convenient to stow in a car trunk or closet.


Doors and Access Points
The four doors (front, back, both sides, plus the top) offer flexible access, which is handy for different situations like vet visits, feeding, or sun exposure. You can leave one or more doors open and secure them with the straps that roll the fabric doors up to keep the interior accessible.
Security Features
Each front and side door has a zipper and additional lock clips to add security and reduce the risk of accidental openings. While the zippers and clips increase safety, you should still supervise pets that try to paw or mouth at the closures.
Comfort and Interior
Inside, you’ll find a removable fleece pet bed pad that adds immediate comfort and warmth for your pet. The soft walls produce a cozy, den-like atmosphere that many cats and small dogs find calming, especially in unfamiliar surroundings.
Bed Pad and Flooring
The included fleece pad is cushioned enough for short trips and resting, and you can remove it for washing or replacement with another pad of your choice. The water-resistant base beneath the pad provides a barrier against minor leaks and makes cleanup simpler if accidents occur.
Setup and Folding
Setting this kennel up takes only seconds: you pop it open and the frame expands to shape the crate without tools or assembly. Folding it down is likewise quick — collapse the frame and secure it with the included straps or packing design.
Time to Set Up
You’ll likely be able to set the kennel up in under a minute the first few times, and you’ll speed up as you get used to the motion. If you plan to move between locations frequently during a trip, that speed is a major convenience.
Stowing and Transporting
When folded, the kennel becomes compact and relatively flat, so you can carry it with the handle or shoulder strap or tuck it into car storage. This makes it practical for weekend getaways, car trips, or bringing to vet appointments where space is limited.

Cleaning and Maintenance
Routine cleaning is straightforward: remove the fleece pad for machine washing if needed, and wipe down fabric surfaces with a damp cloth and mild detergent. The water-resistant base makes it easier to clean spills without liquid soaking into the floor material.
Washing the Bed Pad
You can machine wash the fleece pad on a gentle cycle and air-dry or tumble dry low depending on care instructions. Regular washing helps control odors and keeps the interior comfortable for your pet.
Cleaning the Fabric and Base
Spot clean the fabric panels and the water-resistant base using mild soap and water; avoid harsh chemicals that could degrade the material or irritate your pet. After cleaning, allow the kennel to dry completely before folding it away to prevent mildew.
Use Cases and Suitability
This kennel is ideal for short trips, vet visits, indoor containment at home, and temporary outdoor use under supervision. It’s particularly effective for pets that are calm to moderately active and who don’t chew aggressively.
For Cats
Cats often appreciate the soft sides and cozy interior, and the top door gives them an additional observation point to feel less confined. The lightweight nature makes it easy to move the crate to different rooms so your cat can stay with you.
For Dogs
Small to medium dogs that are well-behaved in crates will find this unit convenient for travel and indoor use. If your dog is anxious or highly energetic, you should evaluate whether a sturdier, hard-sided crate is a better fit.
For Other Small Animals
Rabbits, guinea pigs, and other small animals can use the kennel for short supervised outings or travel to the vet. You’ll want to ensure that any small animal can’t squeeze under or through gaps, and always monitor them to prevent escape attempts.
Safety Considerations
Safety mostly comes down to matching the kennel to your pet’s temperament and ensuring zippers and clips are secured. You should never leave a pet unattended for long periods in a soft-sided kennel if they have a history of trying to chew or escape.
Ventilation and Visibility
The mesh panels and top door provide good airflow and sightlines, so your pet won’t feel fully isolated and you can keep an eye on them. For hot climates, the mesh improves ventilation, but you should still avoid leaving pets in direct sun without shade.
Zipper and Clip Safety
The zipper lock clips help prevent accidental openings, and you can double-secure doors with the included straps when leaving them rolled up. If your pet is an escape artist, consider additional supervision or alternative containment methods to ensure they don’t unzip themselves.

Performance in Travel and Home
For travel, the lightweight construction minimizes bulk and makes moving the kennel quick and simple. At home, you can use it as a temporary safe space for rest, recovery after minor procedures, or to confine a pet for short durations.
Car Travel
In a car, you can place the kennel in the back seat or cargo area and secure it to minimize sliding, though the crate is not designed as a crash-tested vehicle restraint. Use extra precautions like seatbelts or other anchors to stabilize it during transit.
Indoor Use
Indoors, the kennel doubles as a portable bed and quiet corner when you need your pet contained for a short period. It’s also handy for overnight stays at friends’ or family’s houses where you don’t want to leave your pet loose.
Pros and Cons
You’ll find numerous benefits to this kennel, such as portability, multiple doors, and a comfy pad that’s easy to remove for washing. On the downside, the soft-sided build means it’s not suitable for aggressive chewers or pets that require a very secure, permanent enclosure.
Pros
The pop-up design, four-door access, included fleece pad, padded shoulder strap, and water-resistant base make this a convenient all-around travel kennel. You’ll also find it affordable and lightweight compared to many hard-sided alternatives.
Cons
If your pet chews, claws, or tries to escape, the fabric and zippers could be compromised over time, and the crate is not crash-tested for vehicle safety. For long-term containment of a very active or anxious animal, a harder, sturdier crate would be more appropriate.
Comparison with Similar Products
Compared to hard-sided crates, you’ll notice a significant difference in durability and security but a corresponding advantage in weight and packability. When you compare this Amazon Basics soft-sided crate to other soft-sided options, it stands out for its 4-door design and included pad, though materials and zipper quality can vary across brands.
Compared to Hard-Sided Crates
Hard-sided crates usually offer stronger containment, better durability against chewing, and more secure anchoring for travel, but they’re heavier and bulkier to transport. If security and crash-tested safety are priorities, you should consider a hard-sided option; if portability and ease of setup are more important, this soft-sided crate fits well.
Compared to Other Soft-Sided Crates
Many soft-sided crates share similar features, but this model’s top door and four access points add convenience you might not find on simpler designs. The included fleece pad and padded shoulder strap give it a small edge in comfort and transport features compared with some basic soft-sided carriers.
Size Guide and Choosing the Right Size
Choosing the right size is essential: your pet should be able to stand up, turn around, and lie down comfortably inside the kennel. For this medium model (30 x 21 x 21 inches), it’s best suited for small to medium breeds and most adult cats.
How to Measure Your Pet
Measure your pet from the tip of the nose to the base of the tail for length and from the floor to the top of the head for height, and add a few inches for comfort. If your pet is between sizes or you’re unsure, size up to allow a little extra room for standing and turning.
Weight and Breed Considerations
While the crate dimensions are fixed, matching those dimensions to your pet’s size rather than just weight is more accurate. A tall-but-slim dog might need a taller crate, whereas a short-but-heavy dog could fit more comfortably into this medium size if length and height are within the crate’s limits.

Tips for Training Your Pet to Use the Kennel
Introduce the kennel slowly so your pet associates it with positive experiences: treats, toys, and short, calm sessions inside are effective methods. Use the crate as a comfortable retreat rather than a punishment, and gradually increase time spent inside as your pet becomes more relaxed.
Encouraging Positive Associations
Place favorite toys or treats inside the crate and feed meals near or inside it to build positive associations. If your pet shows hesitation, start by leaving the doors open and letting them approach and investigate without pressure.
Handling Separation Anxiety
If your pet shows stress when confined, don’t force long periods initially — short, progressively longer intervals help build trust. Consider calming aids like a favorite blanket, pheromone sprays, or gentle background noise to make the crate feel more secure.
Troubleshooting Common Issues
If your pet tries to paw at or unzip the doors, keep a close eye and consider extra measures like supervised crate time or a sturdier option for problem behaviors. For bad odors, remove the pad, wash it, and clean the base promptly; persistent smells may require deeper fabric cleaning.
Zipper Problems
If a zipper gets stuck, don’t force it — apply a small amount of zipper lubricant or rub a graphite pencil along the teeth, then gently work the zipper back and forth. Regularly monitor zippers for wear and replace or repair as needed to maintain security.
Moisture and Mildew
If the kennel gets wet, fully dry it before folding and storing to prevent mildew. If mildew appears, clean affected areas with a mixture of water and mild detergent, rinse well, and allow to air-dry in a ventilated area.
Frequently Asked Questions
You likely have questions about daily use, safety, and care — here are answers to common concerns to help you make the most of this kennel. These should clarify suitability and routine maintenance so you can decide confidently.
Q: Is this kennel suitable for long-term crating? A: This model is best for short- to medium-duration use; it’s designed for travel and temporary containment rather than continuous, long-term confinement for large dogs or chewers.
Q: Can I use the crate in a car? A: You can use it for car travel for short trips, but keep in mind it’s not crash-tested as a vehicle restraint, so additional stabilizing measures are advisable for safety.
Q: Is the fleece pad machine-washable? A: Yes, the removable fleece pad is designed to be cleaned; follow care label instructions for machine washing and drying.
Q: Will my pet be too hot inside? A: The mesh panels and top door allow airflow, but you should still avoid leaving the crate in direct sun or hot conditions for extended periods.
Q: What do I do if my pet chews the fabric? A: If chewing becomes a problem, consider switching to a more durable, hard-sided crate or supervise crate time closely and redirect chewing behavior to appropriate toys.
Final Recommendation
If you want a lightweight, easy-to-store travel kennel for calm to moderately active pets, this Amazon Basics 4-Doors Portable Soft-Sided Folding Travel Crate is a solid value choice. It offers convenience, multiple access points, and a comfy pad, but you should select a more robust alternative if you need heavy-duty security or crash-tested vehicle safety.
Closing Notes
You’ll find this kennel useful for short trips, vet visits, and temporary indoor use when you prioritize portability and convenience. Remember to match the crate to your pet’s temperament and size to ensure safety and comfort for every outing.
