30cm x 40cm. The color is the gray color in the first photo. It has a cute design with a cat paw pattern and is non-slip. When a cat enters and exits the litter box, the mat's string-like fibers catch the sand attached to its paws, preventing the sand from scattering. You can easily remove dirt with a vacuum cleaner, and it's made of durable and waterproof PVC material, so you can wash it with water or wash the whole thing, making it easy to care for! In addition to being a sand-trapping mat or a litter box mat, it can also be used in various places such as the entrance or as a mat for food bowls. This product is an overseas, no-brand item.
