So I struggled finding a carrier for my big cat (he's like 18-20 lbs - practically a small dog). I bought 2 other carriers before this, one too big that wouldn't fit in my car (I drive a Chevy Cruze) and one that he didn't fit in at all. Then I finally found this one, and it's perfect! My cat fits right in perfectly and the carrier can be easily put into my car now!  In addition, it took about 30 seconds to set up, and my cat loves it! He sleeps inside it all the time. There's also a pouch on top that you can easily place your cat inside when he's afraid because he knows it's time to go in the car.  I'm very pleased with this cat carrier and I recommend it for anyone with a large cat, or someone who has a hard time stuffing their cat into a smaller carrier without a pouch on top.
