The backpack is as the description. It works great as a backpack and carrier.

I love the backpack! I have two small chihuahua's and they have a lot more room then their old backpack. It's also nice I can extent it when we have stopped for a while.

My 3-year old cat isn’t fond of going on walks and trips in his backpack, but I now think it was because the one he’s had (the kind with the bubble in the middle) was too cramped for him. As soon as I put the pidan bag on the floor, he instantly took to it and began hiding and playing inside of it! I have yet to use it with him in it on a walk, but so far it seems very spacious and sturdy—even for a 14 pound tabby!

My cats love it! We call it the kitty palace. They all fight over it. I love how it expands so they can lay down

Got 2 new Teacups who consider this their bed, hiding place and escape route. It's more than I expected, opened or closed. Everything is well designed and durable. Buying more from Pidan.
