The Windmill SPIN bowl, level, EASY, by PetDreamHouse is a dynamic slow-feed pet bowl that turns 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.
