Petsfit 17" x 11" x 11" Airline-Approved Expandable Pet Carrier, 2X Square Expansion Reduces Pet Anxiety, Escape-Proof Self-Locking Zippers, 5 Easy-Access Entrances, for Cats & Small Dogs up to 15 lbs

I bought two of these for my two cats, and it was perfect. I was able to open up one wing for a litter box, and the other wing so they could sprawl out. It was sturdy, and by re-arranging the inner flaps, you can make it so you can open up the wings without having to unzip the carrier, so there is no risk of your pets getting out while you do so. I cannot recommend these carriers enough!

I have several cats and several pet carriers. This is by far the best carrier I ever purchased! All my cats love it. I have cats that weight 7 lbs and cats that weigh 13 lbs and they all fit comfortably. When it comes to plane travel, this is absolutey the best! When you are waiting at the gate, you can open both sides and give them extra room. The fact that the sides are squares is really good, since it truly gives them enough space to walk around. When on the plane and all zipped up, the mesh is only on the two sides and the top, which is great, as some of my cats find that comforting and makes them feel more secure. For some of the others, I can open one side while I am sitting on the plane, to give them more room. I can even put a small litter box for the smaller cats when the sides are open. For visits at the vet, I am thrilled I can open the carrier on the top or the side, as some of them are hard to pull out, unless I can open the top. I absolutely love it!

The media could not be loaded. Great carrier! Video with my large 12lbs male cat. When fully closed it’s the perfect size for travel and mobility. The extensions allow for a considerable extra space. Zipper and functionality of the structure are great and easy to use. A little bit on the pricy end, but worth every dollar.

Product appears to be well made. The video misrepresents the actual product because only one side is expandable, not both sides. This is disappointing. The stated dimensions are one inch larger in each dimension, but the rigid insert is 18x11x11, which is acutally good for meeting airline requirements. I'm hoping the carriers soft outer parts can collapse a little to fit. We will see.

Our cat loves it when we pull out all the sides.

I purchased this carrier to fly with my two toy poodles(7lb & 5lb) with Allegiant. When I was at the airport I opened both sides for the dogs to have more room then closed the sides when we boarded the plane and for take off. It mostly fit under the seat in front of me. Once we were in the air I opened one side compartment for them to move around more. I’m happy I found this bag and they both fit in it perfect. They love to snuggle and I think they did better flying bc they were in the carrier together rather than in separate ones. They scratched the mesh but were not able to tear it. I brought. Small “blanket” to cover the bag when it the sides were expanded bc my dogs are very social so it helped for them not to be so distracted and hyper.Pics are on Allegiant.The carrier fits under the seat with one side open best if you are in the middle seat bc the the foot room in the middle has a greater width than the window and aisle seats. Pic above is an aisle seat.

I have not flown since I purchased due to pandemic. This carrier is sturdy and well made. I bought this because I can fit both cats in it if needed. Not to carry as they would weigh more than 15 pounds together.I am so glad I didn't buy one of the other carriers. The square "pop out" sides on this are large enough for the cats, a domed side seems like it would be worthless. I keep this carrier open all the time. Both cats love playing and sleeping in it. I use it to transport them to veterinarian etc. I did have to evacuate the house once, only put one cat in each carrier to get them out of the house. It was great for the cat in this carrier when I expanded it for her. The other cat was stuck in the regular size carrier, she was not so happy. I like that I could put them in there together as they love to snuggle.

This is a really great product. The quality is excellent. So what is the downside. The Airline!!! Do not fly Delta with your pet. I made the reservation and had confirmed with them the pet in cabin and also the measurements. First of all pets cannot fly firstclass on intermational flight but all fine on national flights even though the flight within US is longer. Then the have those stupid charger boxes /electricity plugs under the front seats which take away all the space for the carrier. I had purchased premium plus and I had literally no place to put my feet for almost 4 hours.When flying first class on the connecting US flight it was very comfortable I was able to open both extension and my little girl could stretch out nicely - so could I. Abusive the fact they charge almost doble vs the other airlines. $400 for a round trip.Resume great carrier, choose carefully the airline.
