I am selling these items because my cat passed away and it's difficult to have cat supplies in my living space. I have thoroughly cleaned and dried them before listing. Purchased on Amazon on May 5, 2024. Used for approximately 9 months. Size: Approximately 55cm x 55cm x 55cm I washed it outside every Sunday morning. (It didn't really need to be cleaned that thoroughly) Image 5: The bottom mat was soaked in Oxiclean, but some stains remain. This is a consumable item, so please purchase the "PETKIT Toilet MAX Dedicated Mat" shown in Image 6. Thank you.
