Review on 🐾 IOKHEIRA Airline Approved Pet Carrier: Expandable Soft-Sided Travel Solution for Cats, Dogs & Small Animals - Car & Bike Travel Carrier Backpack by Brenda Belcher

I have a convertible pet bag that I used to fly with my cat because the backpack has a handle function. I decided I needed something a little more spacious for XC flying and chose this bag for the expandable side feature. My cat seemed to like that the sides were widening and I was even able to widen it during our 6 hour flight to give it more room under my feet. If I could change anything about this bag to give it 5 stars: 1. The bottom would be stronger so the sides of the bag don't bend on my cat when carrying it. 2. Backpack attachments really work. I couldn't use it as a backpack with shoulder straps either, which is why I chose this bag. 3. More color options Despite all that, I don't regret this purchase, but it's not exactly what I was hoping for. The bottom is not very strong so the bag flexes when I carry the cat. Cannot be used as a backpack although it comes with backpack straps.
