Outdoor cat house. For Nyan-chu-san, this item is currently under discussion. Regarding the use of sales proceeds: A portion will be donated to a cat protection organization. Please check the results report in my profile once a year. Things to note: The styrofoam box is recycled. There may be scratches and stains due to recycling. This is a personal, amateur creation. I have placed it under a roof in a location with minimal exposure to rain and wind, so I do not know the durability under other conditions. Structure: Stacked recycled styrofoam boxes with an entrance hole. Exterior: Wrapped in vinyl Interior: Lined with 3mm aluminum sheet Rain cover: Styrofoam board + plastic board Will be shipped separately from the main body. Please secure with tape when using. Curtain: Bubble wrap Bottom board: Styrofoam board Photos: 1st image onwards Front/Right side/Back/Left side/Top/Bottom/ Inside/Entrance/Bottom board Amateur measurements (cm) Exterior: Width 55 x Height 41.5 x Depth 35 Interior: Width 51 x Height 37 x Depth 31 Entrance: Width 16 x Height 16
