Our large 23.5 x 16 silicone mats are extremely versatile. They can be used to go under food and water bowls or they can also be used to go outside your cats litter box to catch litter. Honestly, we use them for plants, to go under art work, for a dish drying mat and so much more. You decide! These food grade, silicone mats offer high edges that keep food and water trapped in. They are free of chemicals such as BPA, PVC, and Phthalates and are easy to clean by hand, with a wet cloth or in a dishwasher.
