High-quality food-grade ABS material, safe and durable for cats to bite. The 43mm "claw control" design is optimized for a cat's natural hunting instincts, offering better control compared to traditional rolling ball sizes. In intelligent mode, the ball activates with a tap, simulating prey-like movement by rolling, bouncing off obstacles, and automatically adjusting its path. Provides quiet play for cats at night, allowing for undisturbed sleep. Outer layer features a high-density material package for smooth, quiet rolling, suitable for day or night use. Soft, skin-friendly silicone coating ensures quiet rolling, improved grip, increased friction, and enhanced bite resistance and durability. Product includes: 1 x Gravity Rolling Ball, 1 x Type-C Charging Cable.
