【Outdoor Cat Shelter (with Straw)】 Size: Outer dimensions (approx.) Width 62 x Depth 44.3 x Height 44.5 cm Inner dimensions (approx.) Width 50 x Depth 34.5 x Height 41 cm (bottom) ※ There is almost no profit for me on this product. It's mostly volunteer work. I am selling this with the hope that it will help outdoor cats, so I cannot offer a discount. This is a shelter to protect against the winter cold. It's for outdoor use, so it's durable and sturdy. The inside of the styrofoam is very warm, and from what I've researched, it's the best for keeping warm. However, styrofoam alone is light and fragile, so the outside is double-layered with a sturdy plastic case. This prevents it from being damaged by crows pecking at it, and above all, the double layer increases the warmth. Straw is included inside. This product will be shipped with the straw already inside, so you can use it immediately upon arrival. Please check the straw from time to time and replace it if it gets damp m(_ _)m Straw is also sold online. It's better to use straw that is cut long, as finely cut straw can stick into the cat's body^_^ ※ Blankets, rugs, and towels are not suitable. They absorb moisture and freeze. Straw does not absorb moisture easily and does not freeze. Also, the "amakusa" (a type of seaweed) sold in pet stores is not suitable. Please be careful not to mistake it for straw. The styrofoam lid may be pushed up by the cat, so please secure it with tape in about two places. To prevent it from being blown away by strong winds, please use it with a weight concrete (10 cm) inside. This also adjusts the height of the hole. If there is no roof at the placement location, you can attach a thin tray sold at 100-yen shops to the entrance with caulking. You can also buy caulking at home improvement stores^_^ 【Notes on Sales】 ※ Concrete is not included. ※ Please put in 10 cm thick weight concrete. ※ If there is no cardboard box of the right size, I will wrap it with patched-up cardboard for shipping. It will be a simple packaging. ※ Since the holes are not pre-made, there may be scratches or distortions.
