Moves fast like a mouse with a colorful flashing light strip, the interactive cat toy catches cat's attention at a glance. The kitten toy features two wheels that change in unpredictable ways that delightfully trigger your cat’s instincts: hunting, chasing, pouncing, scratching, having fun, and exercising all in one go. With an intelligent built-in obstacle avoidance sensor, the indoor cat toy runs in random directions and moves away when it hits a wall, furniture, or other obstacles, keeping your cat excited by remaining unpredictable. The two wheels are smooth and sturdy allowing it to run on any type of hard floor such as marble, wood, tils floor, etc. (Note: not recommended for shag like pile carpet, rug).
