The best general material to look for in a cat food mat is silicone as it is easy to clean, is food-safe, naturally non-slip, and shouldn’t absorb any food odors or stains. Rubber is also a durable option although it can be a little hard and inflexible, while plastic can warp and get become misshapen over time. Woven fabric can also be considered although it won’t be water-resistant and can be trickier to clean.
