USB CHARGING - The cat exercise toy has a built-in rechargeable battery. Simply charge it via the Type-C cable (power adapter not included) to avoid the hassle of changing batteries. IRREGULAR ROLLING - The movement tracking of the automatic cat toy is unpredictable, and the tail of the cat ball toy will wiggle as it runs to attract your cat's attention.

It will bring joy and companionship to your cat when you are busy or away!. 3 WORKING MODES - The interactive cat ball has 3 motion modes. Depending on the different light display, you can choose fast rolling - blue light, slow rolling - purple light, or interactive mode - yellow light. When turned on, it also emits a bird chirping sound to stimulate your cat's interest in this smart cat toy. Suitable for cats of different ages and personalities!. SUPER DRIVE - Our motorized cat toys are equipped with a built-in super drive for fast rolling on tile/marble/wood/carpet floors.
