Review on Nooyi Cat Carrier Dog Carrier Puppy Carrier, Airline Approved Pet Carrier, Soft Sided Collapsible Pet Travel Carrier for Small-Medium Cats and Small Dogs up to 15 lbs - Black/Grey by Jennifer Tillman

It serves the purpose and was a great suggestion. The cats like it enough to use as a bed/cabin when I leave it unused. My only complaint is that the zippers are difficult to get around the sharp corners of the small door. I think I'd go with something more expensive for more intensive trips, but if you just need something for quick trips to the vet I'd definitely recommend this one.
