The Windmill SPIN bowls, level, MEDIUM, by PetDreamHouse are dynamic slow feed pet bowls that turn mealtime for your dog or cat into fun and interactive feeding. SPIN bowls encourage sniffing, licking, and problem-solving during meals, which naturally slow eating and prevent choking, bloating, and excessively fast eating. Each bowl has a multi-functional center puzzle element that can be adjusted in height to offer variation or flip it over to create a whole new option. Each bowl has four large anti-skid rings to provide high stability.
