Powerful Driving Force: The powerful motor allows the interactive cat ball to move quickly on thick carpets, thin carpets, and hard floors. Skin-Friendly Material: The surface of the ball is made of flocking and silica gel. The fluffy feel attracts cats to approach it. The 2.3-inch size is suitable for adult cats and kittens. You can regularly clean the dirt on the surface of the ball. Two Interaction Modes: Press and hold the button for 1 second to turn on the slow mode (the red light flashes and then turns off). It is suitable for shy, less active, or older cats. We have specifically turned off the light for these cats to avoid scaring them or harming their eyes. Briefly press the button again to switch to the fast mode (the blue light is constantly on). Motion-Activated: When the cat toy is turned on and you play with your cat for 3 minutes, it enters sleep mode. When your cat pats or touches it again, it activates to play with your cat for another three minutes. Each time it activates, it emits a bird chirping sound to attract cats to chase and catch, stimulating their hunting instincts. Rechargeable: The electric ball has a built-in 600mAh rechargeable battery. It is recommended to use a mobile phone charger and the USB Type-C cable included in the package to charge the interactive cat toy. There is no need to buy additional batteries. Friendly tip: The electric ball toy is not waterproof. Use a damp cloth (included) to clean the dirt on the surface. If you receive a defective ball or encounter problems during use, please contact our customer service team.
