I bought this to reduce the hassle of cleaning the cat litter box and have been using it for a while. There appears to be some dirt on the inside. Please check the condition and only purchase if you are not concerned about this. 60 x 40cm, Size M Non-slip backing [Product Description] The material is soft and foldable, making it convenient for storage. You can lift the mat and return spilled cat litter directly to the cat toilet, or you can collect it with a vacuum cleaner, broom, or cloth and then wash the mat. There are openings on both sides of the mat, and the Velcro-attached parts are removable, making it easy to keep clean.
