This is a curtain for a Petsley automatic cat litter box. I recently purchased this product online, but I didn't check the type of automatic litter box carefully before buying it. It doesn't fit my automatic litter box at home, so I'm selling it. ★Please check the type of your automatic litter box before purchasing. ・Size (one side): Approximately 14cm wide x 21cm high *I opened it for the purpose of taking photos.
