Powerful Propulsion Force: The powerful motor allows the interactive cat ball toy 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 touch 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 toy ball. Two Interaction Modes: Hold the button for 1 second to turn on the slow mode (the red light flashes and then turns off). It is suitable for timid, less active or older cats. We have specifically turned off the light for these cats to avoid scaring them or harming their eyes. Short press the button again to switch to the fast mode (the blue light is constantly on). Motion Activated: After the cat toy is turned on and you play with your cat for 3 minutes, it will enter sleep mode. When your cat pats or touches it again, it will be reactivated to play with your cat for another three minutes. Each time it is activated, it will emit 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 purchase additional batteries. Friendly Tip: The electric ball toy is not waterproof. Please use a damp cloth (included) to clean the dirt on the surface. If you receive a defective ball or encounter any problems during use, please contact our after-sales team.
