Set of 2. Price for purchasing only 1: 1,800 yen/piece. This is a house made for outdoor cats. I hope it will be helpful. I made it for friendly cats. I think they can go back and forth through the side entrances when two are placed side by side. Of course, they can also be used individually. Structure: Two holes were made for the entrances in a styrofoam box made from waste materials. The outside is wrapped in vinyl. A blanket made from waste materials has been cut into quarters, and the edges have been treated. This is the first time I've made a house this year. I have it set up under a roof in a place that is not very affected by rain and wind, so I don't know the durability under other conditions. The styrofoam box and blanket are waste materials. Please understand that there may be scratches and stains, and that this is a personal, amateur creation.
