This is a 0.6cm thick silicone mat that is soft and comfortable. It's made of premium eco-friendly material that's durable enough to clean regularly. With a surface area of 49.5cm x 34.7cm, it's suitable for most litter boxes. The grains are arranged in a ripple and spaced unevenly to trap the litter more effectively. The soft silicone is more gentle on the floor than hard plastic and the mat is flexible and does not slide. This silicon mat is easier to clean than cloth - it can be folded and then emptied, and prevents bacterial growth from forming.
