I have a cat. I used this at home until the cat could hold its head up. After the cat could hold its head up, I used other items for going out. There is a manual, although it is not in the photos. I will pack it simply and ship it as small as possible. Since this is a used item, please only purchase if you understand. I have set the shipping time to be longer, but please consult with me if you need it urgently.
