Morpilot Expandable Cat Backpack Review

I am always a little skeptical of pet backpacks because the good ones solve a real problem, while the bad ones turn a cat or small dog into awkward cargo. The Morpilot Expandable Cat Carrier Backpack sits in the useful middle of that conversation: it is a soft-sided travel backpack with mesh, self-locking zippers, an internal safety tether, padded human-facing comfort features, and an expandable rear section that gives a pet more room once you are stopped.

As The Pet Dude, I look at a carrier like this through two lenses at once. First, does it make travel easier for the human carrying the pet? Second, and more important, does it give the animal enough security, ventilation, structure, and escape prevention to be a humane way to move through the world? For cats especially, the difference between a tolerable carrier and a panic box can be huge. I like that this one is clearly designed around travel friction points: loading a reluctant pet, keeping airflow moving, letting the pet see out without being exposed, and opening up extra space during waiting periods.

That said, this is not a magic backpack for every cat, every dog, or every airline. The listing says it accommodates cats up to 20 pounds, while the specifications also list a maximum weight recommendation of 25 pounds. I would treat that as a reminder to measure your pet, not just weigh them. A long-bodied cat, a stocky small dog, or a pet that refuses to settle in confined spaces may not be comfortable even if they fall within the listed weight guidance.

What it is

The Morpilot Expandable Cat Carrier Backpack is a gray pet travel backpack for cats, puppies, small dogs, and small animals. The listed dimensions are 13 inches long by 10 inches wide by 16.5 inches high, and the expandable design widens from 10 inches to 22 inches when the rear section is opened. The default color is gray, and the listing also shows blue as an available color.

The Amazon listing positions it as a breathable, foldable, airline-approved carrier for hiking, camping, outdoor use, walking, visits, and general travel. It is made from 600D Oxford fabric and mesh, with 60% high-breathability mesh called out in the product features. It uses zipper closures, including self-locking zippers, and includes an internal safety tether to help prevent escapes when an opening is being used.

In the box, the included components are simple but useful:

• Cat carrier backpack with expandable rear space.
• Foldable bowl for food or water during travel stops.
• Removable and washable plush pad inside the carrier.
• Storage pockets for small travel essentials.

The backpack is sold under Morpilot model PA001GR00NBA. Morpilot says its pet series was founded in 2015, and the brand describes its products as travel-focused gear for both adventure-seekers and city pet parents. The listing also says Morpilot has been certified as a Climate-Pledge-Friendly brand since 2024 by tracking product carbon footprints and taking steps to reduce impact.

Available colors

Color choices are limited, but they are practical for a travel carrier. The listing shows:

• Gray
• Blue

I would call the gray the safer pick if you want a modern, neutral carrier that does not shout “pet backpack” from across the room. Blue gives you a little more personality without turning the carrier into a novelty item.

First impressions and setup

The first thing I care about with any pet carrier is whether setup feels fussy. When you are dealing with a nervous cat, an excited puppy, or a small animal that would rather be anywhere else, fiddly gear can turn a simple trip into a wrestling match. This Morpilot carrier is straightforward to set up. The zippers move smoothly in regular use, and the expandable back section is the feature that makes the bag feel more versatile than a basic rectangular soft carrier.

The backpack has multiple access points, which matters more than people think. Some cats are easier to guide through a top opening. Some small dogs are more comfortable walking in through a front entry. Having options gives you a better chance of matching the carrier to the pet instead of forcing the pet to match the carrier.

The structure feels fairly stiff for a soft backpack. That is a plus for the animal inside because a floppy carrier can collapse inward and make a pet feel trapped. The internal pad gives the floor a cozier resting surface, and because it is removable and washable, it is not a one-accident-and-you-are-done situation.

I also appreciate that the backpack is foldable. Not everyone has room to store a hard kennel between trips, and a foldable travel carrier is much easier to keep by the door, in a closet, or ready for professional-day emergencies. The listing does not give folded dimensions, so I would not buy it assuming it will fit into a specific tiny storage space without checking the manufacturer’s current images or details.

In daily use / hands-on testing

In daily use, the Morpilot backpack makes the most sense as a short-to-moderate outing carrier: errands, walks, car rides, visits, camping check-ins, hiking breaks, and airport waits. It is especially appealing for cats that do better when they can see their person and peek out at the world through mesh rather than being sealed into a dark carrier.

The expandable section is the star. When the backpack is fully closed and worn, the pet is in the main carrier footprint. When you are parked at a gate, sitting outside, resting at a campsite, or waiting before an appointment, the rear panel opens into a roomier mesh “porch.” That extra space lets a pet stretch, turn around, or settle in a more relaxed posture. For anxious cats, that can be the difference between constant repositioning and actual calm.

The carrier also works nicely as a temporary safe zone. I like using this style of backpack as a mobile den: the pet is contained, the mesh gives visibility and airflow, and the internal tether adds a backup layer when I need to open the top. The large top opening is useful for checking on a pet or offering reassurance, but I do not treat it as an invitation to let a cat ride around with their head out unless the cat is harnessed, tethered, calm, and closely supervised.

For cats

This is most naturally a cat backpack. The listing specifically calls it a cat backpack carrier and says it comfortably accommodates cats up to 20 pounds. In my opinion, the best cat fit is an indoor or indoor-supervised cat that is curious but still wants a protective shell around them. Shy cats may benefit from the sense of enclosure, while confident cats may enjoy the side viewing windows and airflow.

The expandable rear section is also helpful for cats because cats hate feeling pinned in place. Once settled, they can sit upright, lie down, or turn around depending on their body shape and comfort level. A calm senior cat may appreciate that the carrier stays fairly structured and gives them a padded base. A younger, high-energy cat may need slow introduction and treats before expecting peaceful outdoor strolls.

I would not use this as a shortcut around carrier training. Leave it open at home, let the cat investigate, place the plush pad inside, and build positive association before the first real trip. A cat that only sees the backpack right before a professional may decide the backpack itself is the problem.

For small dogs and puppies

The listing describes it as suitable for puppies or small dogs, and the Amazon specifications list dog breed size as large, medium, and small. Practically, though, the dimensions and cat-focused design make this a small-pet carrier. I would focus less on breed label and more on whether the dog can sit, turn, and rest inside the 13 by 10 by 16.5 inch carrier footprint.

For a puppy or small adult dog that likes being carried, this can be handy for walking routes, camping, travel days, and busy places where paws on the ground are not ideal. The foldable bowl is a nice add-on for outdoor stops. The mesh matters for dogs too, especially if they get warm or overstimulated in closed carriers.

Where I would be cautious is with strong diggers, scratchers, or escape artists. The backpack has self-locking zippers and an internal safety tether, but it is still a soft carrier made with mesh. A determined dog that chews, claws, or panics against confinement is not the best match for any mesh-sided backpack.

For airport and car travel

The title describes the carrier as airline approved, and the expandable section is very useful for terminal waiting. The luggage strap on the back is one of those small travel details I like because it can make airport navigation much less clumsy when paired with rolling luggage.

Still, airline approval is not universal in real life. Airlines have their own carrier size rules, under-seat requirements, and pet policies, and those can change. The smart move is to confirm the current airline requirements before you travel, especially because the backpack’s expandable section is meant for when you are stopped, not necessarily for fitting under a seat while expanded.

For car travel, the listing says the carrier is compatible with vehicle type: car. In practice, I would still secure the backpack so it cannot slide or tip, and I would keep the pet fully enclosed while the vehicle is moving. The internal tether is helpful, but it is not a substitute for thoughtful restraint and supervision.

Materials & build quality

The main materials are 600D Oxford fabric and mesh. The listing describes the 600D Oxford cloth as heavy-duty and scratch resistant, and the mesh as high-breathability. The carrier has a modern backpack layout, widened and thickened shoulder straps, enhanced back support, zipper closure, self-locking zippers, and a removable washable plush pad inside.

In real-world use, the build feels better than a bare-bones soft carrier. The fabric has enough body that the backpack does not feel like a collapsing tote, and the mesh panels give the pet multiple sightlines without making the entire bag feel exposed. The zippers are an important part of the experience. Smooth zipper action matters when you are trying to load a pet calmly, and self-locking zippers matter because curious paws and noses can be surprisingly clever.

The mesh is the part I would watch over time. In normal use, it holds up well enough for casual walks, travel, and errands. But mesh can show scratches if it meets sharp twigs, thorns, claws, or persistent digging. That is not a dealbreaker for me; it is the tradeoff that comes with a breathable carrier. I would inspect the mesh regularly, especially before a trip, and I would not assume any soft mesh carrier can contain a panicked power-scratcher forever.

Comfort for the human

The backpack has widened, thickened shoulder straps and enhanced back support to distribute weight more evenly and reduce fatigue. It also has a chest and abdomen-style stabilization feel in use, which can help the carrier ride more securely. For errands and short walks, I find this style much more comfortable than carrying a traditional hand carrier on one side of my body.

I would not oversell it as a dream pack for long, hard hikes with a heavy pet. The padded straps are comfortable enough for ordinary use, but a living passenger shifts weight differently than camping gear. If your pet is near the upper end of the listed size guidance, you will feel that weight more than you might expect.

Comfort for the pet

The plush pad gives the pet a soft floor, and the removable/washable design is a practical win. The expandable space is where pet comfort really improves. When opened, the carrier widens from 10 inches to 22 inches, creating more lounge room. For cats that like to stretch or small dogs that dislike being curled up too long, that is a meaningful design choice.

Ventilation is another comfort point. The listing calls out 60% high-breathability mesh, and the carrier has side viewing windows plus a large top opening. For sensitive cats, airflow and visibility can reduce that trapped-in-a-box feeling. At the same time, visibility can also overstimulate some pets, so know your animal. Some cats want the world; others want a towel over part of the carrier.

Cleaning and maintenance

The listing describes the materials as easy to clean and the plush pad as removable and washable. That is exactly what I want in a travel carrier because pet backpacks collect fur, treat crumbs, outdoor dust, and the occasional accident. The foldable bowl is also a good travel extra because it gives you a dedicated dish instead of improvising on the go.

My maintenance routine for a backpack like this is simple:

• Shake out loose fur and crumbs after each outing.
• Remove the plush pad when it needs a wash.
• Wipe the interior surfaces after muddy, rainy, or high-stress trips.
• Inspect zipper paths so fur and grit do not interfere with closure.
• Check mesh panels for claw marks, twig snags, or stretched areas before travel.
• Let it dry fully before folding and storing it.

The owner experience around weather is encouraging for light exposure; the fabric handled a few raindrops without soaking the pet in that scenario. I would still not treat this as a rain shelter or weatherproof crate. The listing materials are Oxford fabric and mesh, and mesh is intentionally breathable, not sealed against weather.

Safety considerations

Pet carrier safety starts with fit. The product title says cats and small dogs up to 20 pounds, while the specifications include a maximum weight recommendation of 25 pounds. Because those numbers are not the same, I would use the more conservative mindset: measure your pet, think about body shape, and make sure they can sit, turn, and settle before relying on it for travel.

The safety features I like are the self-locking zippers, internal safety tether, structured shape, breathable mesh, and large top opening for quick soothing. The tether is especially important if you plan to open the top outdoors. However, a tether can create its own risk if a cat tries to leap out and ends up hanging or twisting. That is why I only open the carrier when the pet is calm, harnessed appropriately, and directly supervised.

Here is my safety checklist for this carrier:

• Measure first. Do not buy on weight alone; body length and height matter.
• Use the internal tether correctly. Attach it to a harness, not a collar, for cats and small dogs when escape risk is present.
• Do not leave openings unsecured. Mesh, zippers, and top hatches are only safe when fully closed or actively supervised.
• Inspect mesh before every trip. Scratched or snagged mesh can become a weak point.
• Watch heat and stress. Breathable mesh helps airflow, but it does not eliminate overheating risk.
• Confirm airline rules. The title says airline approved, but airline policies and under-seat fit requirements vary.
• Secure it in the car. The listing says car compatible, but the backpack should not be free to slide around.
• Train gradually. A frightened pet can claw, thrash, or attempt to escape even from a well-designed carrier.

I also want to be very clear about small animals. The listing includes pet type as cat, dog, and small animal, but it does not specify species such as rabbits, guinea pigs, ferrets, or hamsters, and it does not give small-animal-specific safety guidance. For rabbits or other small animals, ventilation and containment are only part of the equation; stress, chewing behavior, and secure footing matter too. I would use extra caution and consult species-specific travel guidance before treating this as a default small-animal carrier.

Durability and longevity

For a soft carrier at a budget-friendly tier, the Morpilot backpack lands well. The 600D Oxford fabric gives it a sturdier feel than bargain fabric bags, and the mesh has enough structure for regular casual use. In longer use, the encouraging pattern is that the backpack can hold up for months of walks and casual outings, with the main cosmetic wear showing on the mesh when it brushes against sharp outdoor debris like twigs or thorns.

That durability profile makes sense. The carrier is designed for travel, walking, hiking, camping, and visits, but it is still a soft-sided backpack with breathable mesh panels. If your pet calmly rides, looks out, naps, and shifts around, I would expect a much better experience than if your pet scratches nonstop or tries to dig through the corners.

The zippers are another longevity point. Zippers that catch or jam can quickly ruin a pet carrier because they make loading and securing stressful. This design’s zipper experience is one of its strengths in daily use, and the self-locking design adds confidence. I would still keep fur and debris out of the zipper tracks and avoid forcing them when the fabric is under tension.

Value

I would place the Morpilot Expandable Cat Carrier Backpack in the budget-friendly to lower mid-range zone for this type of gear. The value is strong because it is not just a basic backpack shell. You get the expandable rear section, breathable mesh, internal tether, self-locking zippers, padded straps, back support, removable washable pad, storage pockets, luggage strap, and the included foldable bowl.

The best value case is a pet parent who will actually use the expandable feature. If you only need a carrier for one short trip a year, a simpler carrier may be enough. But if you do airports, errands, supervised outdoor time, farmer’s markets, camping check-ins, or walks with a cat or small dog, the extra functionality earns its keep.

I also like that it can become part of a pet’s routine at home. A carrier that a cat voluntarily naps in is worth more than one dragged out only for stressful appointments. Leave it accessible, make it familiar, and it becomes less of a trap and more of a portable den.

Who this is for / who should skip

Best fit

• Cat parents who want hands-free travel. This is much easier than carrying a traditional side carrier through errands or terminals.
• Curious indoor cats. The mesh windows let them observe without being loose or exposed.
• Small dogs and puppies that enjoy being carried. The carrier is best for pets that can comfortably fit the listed dimensions.
• Travelers who wait around. The expandable section shines at airports, campsites, outdoor stops, and waiting rooms.
• Pet parents who care about airflow. The 60% high-breathability mesh design is a major advantage over darker, more closed-in bags.
• People who want a compact kit. The included foldable bowl and storage pockets reduce the number of extras you need to pack.

Use caution if

• Your pet is near the top of the listed size guidance. The listing mentions cats up to 20 pounds and a maximum weight recommendation of 25 pounds, but comfort depends on measurements.
• Your pet scratches hard at mesh. The mesh is breathable and useful, but it is still mesh.
• Your cat bolts through openings. The internal tether helps, but top-opening use requires close supervision.
• You need guaranteed airline fit. The title says airline approved, but you still need to confirm your airline’s current rules.
• You plan long hikes. The straps are padded, but a pet’s shifting weight can be tiring over longer distances.

Skip it if

• Your pet cannot comfortably sit, turn, and lie down inside. A carrier that technically holds a pet is not automatically humane.
• You have a serious chewer or escape artist. A hard crate may be safer than a soft mesh backpack.
• You need a carrier for unsupervised containment. This is travel gear, not a crate replacement.
• Your pet panics in backpacks or high-visibility carriers. More mesh is not always better for every temperament.
• You need species-specific small-animal travel features. The listing says small animal, but it does not provide detailed species guidance.

Verdict

The Morpilot Expandable Cat Carrier Backpack is one of those pet products that makes immediate sense if your life includes travel, errands, or outdoor time with a small companion animal. The expandable rear compartment is not a gimmick; it meaningfully improves comfort when you are stopped. The 600D Oxford fabric, breathable mesh, self-locking zippers, internal safety tether, padded shoulder straps, back support, washable plush pad, storage pockets, luggage strap, and foldable bowl add up to a practical travel setup.

My main cautions are fit and temperament. The listing gives a cat comfort claim up to 20 pounds and a maximum weight recommendation of 25 pounds, but numbers do not tell the whole story. Measure your pet, think honestly about whether they claw or panic, and do not use the top opening casually with a cat that may launch. The internal tether is a backup safety tool, not permission to relax your supervision.

For calm cats, carrier-trained cats, small dogs that like being carried, and pet parents who want a hands-free way to move through airports, sidewalks, offices, and casual outdoor settings, this is a very solid buy. It is budget-friendly for the feature set and feels more thoughtful than a plain fabric carrier. I would not choose it for a destructive escape artist or as a hard-crate substitute, but as a portable, breathable travel den, it gets a strong nod from me.

Check before you buy

• Measure your pet against the 13 x 10 x 16.5 inch listed dimensions.
• Remember the expansion widens the space from 10 inches to 22 inches when opened.
• Confirm your pet’s weight against the listing’s cat guidance up to 20 pounds and maximum weight recommendation of 25 pounds.
• Check airline rules before flying, even though the listing describes it as airline approved.
• Decide whether your pet likes visibility. Mesh is great for airflow, but some pets prefer more visual cover.
• Inspect the mesh regularly if you walk near brush, twigs, thorns, or if your pet scratches.
• Use the internal safety tether thoughtfully and supervise any open-top moments.
• Choose your color: gray for neutral, blue for a little more personality.
