This carrier is perfect. It has 2 ways to get your pet in and out, is collapsible so it is out of the way when not in use, and easy to carry. I have 3 of them. 2 are the smallest size and perfect for one cat. The other is a medium and I use it for my 2 one year old brother cats who each weigh about 8 ponds on our frequent 4 hour trips in the car.
