A comfortable M-size bed for cats with a warm far-infrared kotatsu. - Brand: NYANTA CLUB - Model Name: Far-Infrared Kotatsu - Size: M - Included: Instruction manual Thank you for viewing. I purchased this last year for my beloved cat, but unfortunately, he passed away without using it much, so I only used it about 2 or 3 times. The box is a little damaged from opening, but the product itself is almost as good as new. It is considered a used item, so if you understand this, please consider purchasing it.
