Each set contains three stainless steel bowls and three silicone lids. Designed for independent use or can be integrated with a Messy Mutts silicone single or double feeder system (manufacturers item code MM010- and MM020-) for additional help to keep the bowls in place and contain the mess. Prepare raw meals ahead of time, thaw and keep fresh in the refrigerator. The lids are air-tight, stackable and spill resistant (even with liquids - check out the video) which also makes them great for travel, dry or wet food if you furry friend does not finish their meal. Reduce the mess in your kitchen by prepping your meals in the same you’re your dog eats from…and then putting it in the dishwasher! Stainless bowls are non-toxic and rust resistant. Lids are made from food-grade safe silicone, and are BPA and PVC Free. All components are dishwasher safe.
