This is a cooling and heating dome-shaped house for small dogs and cats. I purchased it about three weeks ago. The black mat for summer use is not included. There is a warranty and instruction manual, so you should be able to purchase it by contacting the company. Although I have never used it, I am listing it as "Like New" because the sheet is missing and the item has been opened. Model: RM24001GRY Retail Price: 24,800 yen (tax included)
