I bought this about three years ago for my cat. I only looked inside the box after opening it, and never used it. I wanted to try it out while I was at home, but I was often away, so I never had the chance to use it and just left it. I don't plan to use it, as I'll continue to keep my cat warm with blankets, so I'm selling it. I often see these used in pet shops. The retail price was in the high 7000 yen range. I bought it at a pet shop for about 6900 yen. It's unused by my cat, and I haven't put it in their bed. For those who want an unused item. It's been stored at home, so the box may have some scratches. When shipping, I'll decide whether to send it in the box or to flatten the box. Please let me know if you don't need the box. It's out of season, but I'm currently decluttering, so I'm selling it. The Hokahoka Mat DX is a warm heater for pets. - Brand: KOJIMA
