Siivton 4 Sides Expandable Pet Carrier, Airline Approved Soft-Sided Dog Cat Carrier Bag with Fleece Pad for Cats, Puppy and Small Animals (4 Extension Gray_Blue, L:18.0″ L x 11.0″ W x 11.0″ H)

Fantastic carrier!
I purchased this in June of 2021 and waited until now, February of 2022, to write this review (I wanted to really test it out and see how it held up) and I’m pleased to say I absolutely love this carrier! Keep in mind the attached photos are current so pardon any soil/hair you may see but I wanted to show how it has held up after 8 months.SPACE:I purchased the x-large in case I needed to put both cats in one bag in the event of an emergency then once in a safer place I could open the sides to let them spread out. For regular use it provides my 10 lb cat with a ton of space.SHAPE:Other carriers I’ve had have all ultimately succumbed to collapse and/or the metal rods giving it shape have bent or the tabs holding them in place have ripped. This carrier has maintained its shape and has proven very durable.DURABILITY:Another plus for me is the durability of the mesh used. Said 10 lb cat is not a fan of carriers, or anything that restricts her movement, and has destroyed many a mesh inset. She had a couple of episodes in this carrier and the mesh came out of it no worse for the wear. While she was able to force her claws in the tiny space she was not able to rip through it like she did the others. The zippers are strong and easy to work.FEATURES:I love the ability to open all 4 sides. It allows more options to open the sides when setting the bag down on different sized surfaces. It comes with the standard top and front side access that most carriers have but it goes a step further in allowing access via all the mesh expansions as well. In total you have the 2 animals access points when closed and 5 when expanded! I like this for security reasons if ever there’s an emergency and you need to get your pet out fast. There’s a good sized, secure pocket on one long side to hook over the pull handle of rolling luggage which I also use to loop a seatbelt through in the car. On the same side are 2 tabs for use with straps in a car to attach to a seat or to hang items from like a leash, poop bags (for dog owners), or additional storage/supplies bag(s).The downsides:There’s only a couple of changes I would make to this bag. They’re more of just a nitpick on my part and things I hope the company will consider if they every revamp the bag…1. There are little velcro tabs on the inside (1 on each length) to help keep the folded mesh contained. They are not very strong and won’t stay hooked. Luckily the mesh is pretty thick and, in combination with the supports, stays in place but it’s still a bit annoying because it can encroach on the available space. I plan on adding my own extra strong, and longer, velcro pieces to each end of the long sides at the very least.2. Storage space. There is 1 pocked on the narrow back side but it’s very thin and you really can’t put much more in there than a couple of receipts. I have small hands but even I have to squeeze my hand in there and the zipper teeth scrape it. I’d like to see a more spacious pocket when I can store the cats collars and tags when they are home as well as a baggy of food, the tube of medication one of them is on, a small comfort toy (one has anxiety), and emergency information on my girls and how to reach myself or vet for when we are traveling. Right now I have a small makeup bag attached to hold this stuff. It works but it gets in the way and really kind of ruins the aesthetic since it doesn’t match and swings around.

Great carrier! Fit on Alaska Airlines Flight!
This was the third carrier I bought that I was finally satisfied with. I purchased the Large 18X11X11 and was able to fit my 18lb shih tzu no problem. The expandable sides were a game changer! When we were sitting at our gate, we could expand all four sides to make more of a “pen” for him. Then, when we were on the flight, we could expand one to two sides to give him some more room. As you can see from the photos, he stretched out and fell asleep!There are only a few things I would change about this carrier, which is why I’m only giving it four stars.1. The base of the carrier is not very sturdy. This could be because my dog was over the recommended weight limit for the carrier. However, compared to other carriers I’ve tried, it still felt flimsy. I actually took the bottom out of a different carrier (much thicker plastic) and put it in this one and then had no issues of the carrier folding in on itself when my dog was inside.2. The outside pocket on this carrier is pretty much useless. I couldn’t even fit a ziplock bag of treats in it, let alone a leash. It could hold my leash if I was sitting down, but as soon as I would start walking around, it would fall right out of the top of it.3. I don’t love that there is only one zipper to zip the entire carrier together. This pretty much forces you to load/unload your dog on one side and one side only.4. The strap is VERY uncomfortable. I wish it was a touch more padded. My shoulder was pretty much dead walking through the airport with my dog inside. Wheels would be amazing, but I’m sure there are more expensive carriers out there with wheels.5. Once you lay down the mesh, expandable sides, and go to put them back in place, they do not stay in place and tend to fall slightly inside of the carrier. This takes up some room for the animal inside.Other than these five things, I really liked this carrier. The expandable sides are what sold me on it. I had zero problems with my four Alaska airlines flights! I did buy this carrier about two months in advance for my flight and did a TON of training with my dog. Highly recommend doing that with anyone getting ready to fly!

Me encantó la maleta porque fue muy cómoda para mi perrito, sin embargo no fue muy cómodo cargarla porque mi perro pesaban 8 kg y para ese peso las correas lastiman un poco. La primera foto es de un vuelo con Volaris y la segunda con Air Europa en ninguna aerolinea tuve problema con el tamaño ni el peso pero en Volaris iba muy incómodo el perrito, la recomiendo para vuelos largos y en asiento con extra espacio para las piernas sino no cabe bien. En ningún avión cupo completamente debajo del asiento normal.

su extension para poder viajar comodamente

Great product thank you
