Review on MOV COMPRA Wheeled Pet Carrier Backpack Stroller: Travel Carrier, Car Seat for Small Dogs, Cats & Puppies with Comfortable Cat Backpack, Removable Rolling Wheels – Mesh Ventilation Windows & Storage Pockets by Amy Perry

I love this carrier. I know it's meant for cats but I love that it stands upright so my child can sit in it while people watch what their favorite activity is. It's very well ventilated. Two things I really like are that the wheels come off with the push of a button and not by unscrewing them or anything like that. All you have to do is remove the wheels and place them horizontally, and on American Airlines it fits under the seat in front of you. The backpack portion is good, but I wish there was a better way to tuck the straps in if you don't intend to use them. They are a bit long and can get tangled in the wheels. It is very easy to twist and turn with 360 degree action. It's also very well ventilated for my pup.
