This is an Aukatz cat litter box system (without a sand-trapping mat). Used for approximately 2 years by two cats. The sand-trapping mat has been disposed of and is not included. I am selling this because my elderly cat's legs and hips have weakened, and I have switched to a litter box with a lower step. During the usage period, it was disassembled, cleaned, and dried about once a week. There are scratches and discoloration due to normal use. Please check the photos for details. Please understand that this is a used item before purchasing. *Please check the official website for product details.
