A kotatsu that warms with far-infrared rays, allowing cats to spend comfortably. I bought it for my elderly dog, but because he can't see, he was scared and didn't go in, so I'd like to give it away. I put the dog inside only once, so please purchase only if you understand. I will fold the box and ship it in a small size. If you don't need the box, please let me know before shipping.
