Please read the profile. Thank you. This is a set of the Yukapet LX M size and cover. I purchased it after careful consideration of safety and hygiene for cold weather対策. After opening, my pet used it for about 15 minutes. I didn't expect it wouldn't be liked, so I threw away the box immediately. A typical cat situation. Although it was used for only a short time, please refrain from purchasing if you are concerned. I do not use anything with chemical smells, so those who are concerned about fragrances can rest assured. For those who understand used items, thank you.
