Perfect for one cat only and he can walk in a circle in it and it's sturdy enough for him to sit on top of it. A bit bulky for my back so I wear it on the front so I can see him

I never write reviews, but I had to write one here because of how happy I am with this product. Assembly was super easy, and while the bottom is really structured so that the cat (or other passenger!) can be supported, the bag itself is surprisingly comfortable to wear. The panels allow a great amount of visibility for the cat, and that's a twofold gift: not only are they more secure seeing what's going on around them, but the joy other people get when they see a cat in a backpack is priceless. I did a whole bunch of research before deciding on a bag to make sure it was sturdy, ventilated, and comfortable for the cat, and I'm so glad I picked this one. Attached is our first excursion with our 10-lb cat Autumn to the park- she was quiet and curious the whole time, so I think she may have actually enjoyed the trip too.

Have been using it for over a year and my cat likes it! Great quality and design. I've taken him on walks, vet visits, and 12-hour trip several times. The carrier allows good visibility on the sides for curious cats, and also enough privacy to make them feel secure. If your cat is a scratcher, the plastic definitely prevents escaping. I find it helpful to have a clear and steady backpack for kittens to engage with the environment and people than hiding in a darker carrier for socialization (unless you have a very timid cat!).

 BRAVO to the designers of this cat backpack! I did a ton of product research looking for the most spacious, structured, breathable, and transparent cat backpack for my good-sized Siberian cats. Went for this one and it has not disappointed! Couldn't have designed it better myself. So spacious with high visibility and breathability. Great quality materials. Thick, padded, strong, comfortable straps for the human. And so far the plastic zippered side windows are holding up the structure of the backpack well for my 10.5 lb. girl. She is harness and enclosure-wary but has been most open to this backpack. I can tell on walks that she loves the visibility, solid flat bottom, and sense of safety it provides. I especially love that it is so breathable and allows her plenty of fresh air—that was essential for me. I have not tried it yet with my 17 lb. boy because I'm a little nervous about the zippers holding up and he might be a bit cramped. Will update if I try!

I bought this for my youngest ball python cause shes active and curious.This is a great backpack for small to medium pets of all sorts. Holds bird perches from a dozen angles because of all the air holes (which are just the right size).The clear pannels are side specific. The zippers only match one side, which is why it may seem at first that they dont match up. One clear panel has a zipper pull tab and the other panel does not, just like one side of the backpack has a zipper tab, and the other does not.Other than that mild confusion at the beginning its been smooth sailing.The bottom has nubbies for better and more even balance when set down on a table, which none of the others have.Even with all the ventilation, it gets about 15 degrees hotter inside than whatever temp it is outside. So if your pet cant sweat, or if its suceptible to high heat, its best to get a personal fan (that covers the fan blades well.) and put it inside if youre out in anything hotter than 75 F.Only actual complaint is that the chest strap is REALLY tight. Im a pretty big guy and theres not enough length to cross over my chest and buckle.But for your average, non-landfill-ajacent human being, this wont be an issue.Though ladies may want to wear a compression shirt or super firm support clothing item if they um....if theyre....if they have...Im trying to not be gross, but i think you get the picture.9/10Oh theres no storage at all. Thats a big downside for some, i understand.no pockets or compartments at all.This is 100% designed for space and air flow for the pet, and comfort for your back and shoulders. Nothing else.

One of my three cats is a big boy- and clearly he needs room (yes he's a princess). This bag was a little challenging to put together- I'm not going to lie about that- but it's very durable and collapsible if you're in a small space. After taking it apart and putting it back together a few times it'll get easier! The only downer about this bag is that because it's plastic- if you have a cat that scares easily the small circles that are open for ventilation sometimes make a snapping like sound. Other then this little issue- everything else is great! Bag is great quality and the straps are also surprisingly an amazing quality! If you're on the fence about this bag- it's totally worth a try! Just know you'll need some patience putting it together but it'll be well worth it!

This would've been so perfect if it had been a little bigger. I know my cat is 20lbs and that is over their 17lb weight limit but I wanted to try it out. He just looks a little cramped in it height wise so I decided to return it. He does have an abnormally large frame though for a regular cat. I wish I could've kept this carrier. It was very cool. I liked the window sides and how it was so lightweight.

This backpack is so cute! It's super functional with how small it folds. Great if you don't have the room for a dome backpack since it completely collapses. I haven't used it much but it seems fairly sturdy from what I can tell. My cat is 11 lbs and he has room to sit up but is a little cramped. I wouldn't buy this for a cat bigger than that. Overall, such a great purchase!

 really roomy, love the adjustable handles and all the holes inside. the Velcro's to keep the mat down and the blind up. its a great bag for a great price. a little hard to put on the zipper but this is the only backpack that doesn't collapse on your pet bc it has great structure. very lightweight and big for space. bought other bags and it was terrible, love this one
