Using these pet bowls is easy. Just place them where your pet usually eats. The non - skid rubber base helps keep the bowl in place, reducing the mess from spills. Make sure to clean the bowls regularly. For the parts without the rubber ring, you can simply put them in the dishwasher. The rubber ring should be hand - washed with mild soap and water. Avoid using abrasive cleaners as they might damage the vibrant colors. Store the bowls in a dry place when not in use to prevent rust and odor.
