This is a heated kotatsu for dogs and cats. I'm selling it because my pet wouldn't use it, so it's in beautiful condition. I just bought it and tried to get my pet to go inside once, but they wouldn't, so it's practically unused. I didn't intend to sell it, so I threw away the box, but I have the instructions. It will be shipped folded. Please refer to the photos for detailed instructions and product descriptions. You can also check the product website for more information. I'm selling it at a low price, so I'm not offering any discounts. Thank you.
