This dome-shaped cat bed is made of straw and features a simple, natural design. It's sturdy and well-made. I bought this a few years ago for my cat, but she never used it, so I'm selling it. My cat never went inside, but it's a used item that has been stored at home. Please consider this only if you understand that. Shape: Dome Size: Approximately 36cm in diameter, 23cm in height Entrance: Approximately 12cm (H) x 18cm (W) Measurements are approximate. Please understand. *There are some black spots due to the nature of the material.
