SPIN Bowls encourage sniffling, 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 bowls has four large anti-skid rings to provide high stability.
