Although this item is unused and new, I put cat litter in it once and cleaned it thoroughly. However, as it has been left unused for a while, I am listing it as a used item. I don't think there are any cat odors, but if you are concerned, or if you have a cat, please refrain from purchasing. - Type: Cat toilet - Accessories: Half cover, lower part of the toilet - Design: Two-tiered system toilet - Color: Ivory - Size: Approximately 54cm long, 42cm wide, 15cm deep, and approximately 26cm high (at the highest point) The following is a reprint from the manufacturer's website. Product Features ・No odor for a whole week ※1 ・The upper layer is water-repellent sand, so the structure does not leave urine stains on the sand surface ※2 ・The lower layer has silver ion-infused sheets that suppress 99.9% of odor-causing bacteria ※3 ・Change the sheet once a week and the sand once a month for easy maintenance ※1 ※1. When using a Deotiolet for one cat (up to 8kg). Please remove feces quickly. ※2. Urine stains refer to urine liquid remaining on the sand surface. ※3. Odor-causing bacteria are bacteria that easily generate ammonia from urine. Antibacterial test results by a third-party organization. Not all bacteria are suppressed. Please note that to reduce shipping costs, the item will be disassembled and shipped in one box. Please feel free to ask any questions in the comments. The day of the cat (Nyan Nyan Nyan) is also approaching, so please consider a new cat toilet. Thank you for viewing.
