The vivicreate large cat backpack carrier for travel and hiking is a black backpack with a clear front bubble window, mesh sides and padded shoulder straps. The listing gives its size as 13.38 by 13.38 by 16.53 inches and its weight as 2.5 pounds. The person typing vivicreate large cat backpack carrier for usually wants a hands-free carrier for a walk, a trip or a short ride, and the answer below covers the size figures, the window, the straps and the open questions in the listing.

Quick answer

• The listing gives the backpack as 13.38 by 13.38 by 16.53 inches, which is about 2,959 cubic inches of outside space, and it weighs 2.5 pounds.
• The listing calls it large, but its width and depth are almost equal, and the listing gives no interior size to judge the room a cat will have.
• The listing describes a clear front bubble window, mesh sides, padded adjustable straps and a removable pad.
• Skip it if you need a stated interior size, a bag you can use for a cat that is long in the body, or a load figure that this review can check from outside the listing.

What the listing says the backpack does

The first bullet describes the window. The listing says the transparent front bubble lets the cat see outside. The window is the feature the listing puts first, and it is the reason the backpack is designed as a bubble rather than a solid bag. The bullets do not say how large the window is or how far it extends, so the view is not measured.

The second bullet describes the sides and the air holes. The listing says the backpack has multiple air holes and mesh sides for airflow. The air holes and the mesh are the ventilation features, and the listing does not give their number or their share of the walls.

The third bullet describes the straps. The listing says the shoulder straps are adjustable and padded, and that they have a chest buckle. It says the straps reduce pressure on the shoulders for long wear. That is the listing’s comfort claim, and this review reports it as a claim without a test.

The fourth bullet describes the build. The listing says the backpack has a sturdy base and a shell it calls scratch-resistant. It also gives a pet weight figure, which this review does not repeat, since it is a load claim and no outside source was opened to back it.

The fifth bullet lists the uses. The listing names travel, outdoor walks and hiking, and it adds other uses that this review does not repeat. The title also names travel and hiking, so those are the uses the listing states most clearly.

Size and weight: the arithmetic

The listing gives one size and one weight. The table sets out each figure and the calculation that follows from it.

Figure	Value in the listing	Calculation	Result
Floor footprint	13.38 x 13.38 inches	13.38 x 13.38	179.02 square inches
Outside volume	13.38 x 13.38 x 16.53 inches	13.38 x 13.38 x 16.53	2,959.3 cubic inches
Height above width	16.53 and 13.38 inches	16.53 – 13.38	3.15 inches
Weight in ounces	2.5 pounds	2.5 x 16	40 ounces
Weight in kilograms	2.5 pounds	2.5 / 2.2046	1.13 kilograms
Interior size	the listing gives none	not applicable	not stated

The footprint is about 179 square inches, which is small for a carrier the listing calls large. The width and depth are the same at 13.38 inches, so the backpack is close to a cube standing 16.53 inches tall. The listing does not say whether a cat lies down inside or sits, and it does not give the interior height.

The outside volume of about 2,959 cubic inches is the figure to use for comparison with other carriers. The usable interior is smaller once the walls, the straps and the base are counted, and the listing does not give it.

The weight is 2.5 pounds, or about 1.13 kilograms, and that is the backpack alone. The listing gives a pet weight figure in the bullets, which this review does not repeat.

The window and the view

The clear front window is the feature the listing emphasizes. A cat facing the window can see the road or the trail ahead. The listing does not give the window’s size or its position, and it does not say whether the window can be closed or covered.

Check the window’s clarity and its edges when the backpack arrives. The window is a bubble of clear material, and the listing does not give its thickness or its scratch resistance beyond the shell claim. Test the window’s fit against the zip before a trip.

Mesh, air holes and ventilation

The mesh sides and the multiple air holes are the ventilation features. The listing says they promote airflow. The listing does not give the mesh size, the hole diameter or the number of holes, so the openness is not measured.

The backpack’s interior depends on how the mesh and the window sit against the cat. A cat that presses against a mesh side may feel the mesh, and the listing does not describe the inner surface. Check the inside for rough edges when the bag arrives, and remove any loose parts before the cat rides in it.

The straps and the chest buckle

The shoulder straps are adjustable, padded and fitted with a chest buckle. The listing says the padding reduces the pressure on the shoulders for long wear. The strap length range, the padding thickness and the buckle’s strength are not given.

Adjust the straps to your own body before a walk. Start with the chest buckle and the shoulder straps, then set the length so the backpack sits high on the back. The listing does not give a fitting guide, so this step is general advice rather than the listing’s instruction.

The backpack is a carrier for a cat, so the straps have to hold the weight of the pack and the cat together. The listing does not give a combined weight limit, and this review does not supply one.

Materials, closure and the pad

The specification table lists the material as mesh, plastic and polyester. The window is plastic, the sides are mesh, and the frame is polyester. The listing does not give the thickness of the plastic, the mesh count, or the polyester weight.

The closure is a zipper, according to the specification table. The listing does not say how many zippers the backpack has or where they sit. Test each zipper before the first walk, and make sure it closes fully.

The removable pad is included. The listing does not give its thickness or its fill, and it does not say how the pad is cleaned. Keep the care label and follow it before the first wash.

Car use and the travel label

The specification table lists the compatible vehicle type as car. The listing does not describe a seatbelt loop or a fastening point for the backpack in a car. A backpack carrier is usually taken out of the car, so the car use is a question to check before a trip.

The listing names travel as a use. The travel use is the listing’s own label, and this review does not add any airline, rail or hotel rule. Check the rules for the trip you plan before you take the backpack.

Who this suits, and who should skip it

The backpack suits a cat that fits in a roughly 13 inch square carrier, for a walk or a short trip, with a clear front window and a hands-free strap system. It suits an owner who wants to carry the cat on the back rather than in the hand.

Skip it if you need a stated interior size, since the listing gives none. Skip it if the cat is long in the body, since the outside footprint is about 13 inches square. Skip it if you need a load figure confirmed from outside the listing, since this review does not supply one.

Buying checklist

• Measure the cat’s body length and height, and compare them with the 13.38 inch square footprint and the 16.53 inch height.
• Check the clear front window for clarity and edges before the first use.
• Test the mesh and air holes for rough edges on the inside.
• Adjust the straps and the chest buckle to your own body before a walk.
• Test each zipper along its full length.
• Keep the removable pad’s care label, and follow it before the first wash.
• Check the car and travel rules for your trip before you take the backpack.

Mistakes to avoid

• Calling it large without measuring. The footprint is about 13.4 inches square.
• Assuming the window is large. The listing gives no window size.
• Expecting a stated interior size. The listing gives an outside figure and nothing inside.
• Assuming the straps fit every body. The listing gives no strap length range.
• Relying on the travel label for trip rules. Check the rules for your trip.

How we chose

The keyword for this post is vivicreate large cat backpack carrier for. The research file for it was built on 2026-10-23 and holds six products: the Vivicreate backpack, plus five other listings from the same best-seller category, Pet Supplies > Cats > Carriers & Strollers, with dog products removed. The five others are titles only in the file, and this review uses the listing details for the Vivicreate backpack alone.

We read the Vivicreate listing’s feature bullets and its specification table on 2026-10-23. The criteria were the outside size, the window, the mesh and air holes, the straps, the materials and the car line. The keyword names a backpack carrier from this brand, and the listing is that product, so it was chosen.

The other five were a front-door folding carrier, a single-cat carrier with lockable zippers and buckles, a large carrier for two cats from another brand, a soft-sided large carrier for two cats with a litter box, and an extra large carrier for two cats. Those are soft-sided carriers rather than backpacks, so none answers a hands-free search directly. The closest match is the single-cat carrier with buckles, but it is not a backpack.

What we could not verify

• The interior size of the backpack. The listing gives only the outside size.
• The size and position of the clear window, and whether it can be covered.
• The thickness of the plastic window and its scratch resistance.
• The mesh count, the hole diameter and the number of air holes.
• The strap length range, the padding thickness and the buckle’s strength.
• The number and position of the zippers.
• The thickness and fill of the removable pad.
• The fastening point for the backpack in a car. The listing does not describe one.
• The weight line in the bullets. This review does not repeat it, because it is a load claim and no outside source was opened to back it.
