A nylon portable pet house. All sides are padded with foam and the floor is removable. Zippers close both ends. A mesh inlay at the front of the pet house allows your cat to see out. This inlay also is zippered (not clearly shown in photo). The floor is lined with fleece which ensures your cat is kept warm and comfortable.
I have had a problem in the past that when my cat was brought home from the vet, and still under anaeseptic, she would hit her head and body against the steel rungs of the cat carrier. Since they need to be restrained until the anaseptic wears off so they can't harm themselves or fall down stairs etc, I found this to be the perfect solution.
