SPEED ADJUSTMENT - We have added the slow mode based on feedback from our buyers. You can adjust the speed according to your pet's preferences: long press the power button to switch to fast mode, then short press again to switch to slow mode. BIONIC MOUSE DESIGN: When turned on, the cat toy will move quickly and slowly, moving forward and backward irregularly, just like a real mouse. The glowing LED wheels constantly change color and attract your cat's attention. AUTOMATIC OBSTACLE AVOIDANCE: This interactive cat toy can automatically avoid obstacles and intelligently plan new routes, so you never have to worry about it getting stuck in a corner. AUTOMATIC ON/OFF: After 4 minutes of inactivity, this smart cat toy will automatically go into sleep mode if not touched. When your pet touches the toy, it will reactivate and start moving again, helping to extend battery life. LOW NOISE: This small cat toy is suitable for carpets, tiles and wooden floors. The rubber strips on the wheels minimize noise and prevent scratches on the floor. Note: Our interactive cat toy is only suitable for wood and ceramic floors, not for high-pile carpets.
