Great Pet Carrier for Cats Christine writes about the Avior Pet Carrire, "I already had one avior carrier and needed another because my kittens aren't kittens anymore. Great visibility for kitties. I love how I can open the small part on top and reach in and pat my cats when at the vets. I think they get pretty nervous and it helps. Everyone that see's the avior carrier likes it. Most importantly, my cats like them. Really big opening for them to get in and out of."
