- Strong driver that easily rolls across ceramic tile, wood, low carpet, and high-pile carpet. It rarely gets stuck in corners and is designed to entertain high-energy cats for hours. Note: under the same mode, balls roll slower on carpet than on wooden floor. - Important charging info: uses a 5V/1A adapter only. The cat ball runs for about 5 minutes and then enters sleep mode if not playing; it wakes up again after about 2 hours to check for renewed interest. - Wake-up feature: the toy activates when touched by a paw, helping to engage cats even when you are not home. - Three working modes: Fast mode (blue lights) for fast rolling on high-pile rug, Slow mode (purple lights) for steady movement on floors, Interactive mode (yellow lights) moves only when nudged by your cat. Short press to switch modes; mode is indicated by the light color. - Chirping bird action: realistic bird song to attract interest. The sound can be turned off by quickly pressing the button twice. Please remove fur from the gears occasionally. - The Game of the Braver - Chasing Running Mice: recommended for adult or highly energetic, outgoing cats. If your cat is easily startled by fast rolling, start with slow mode, add heavier tails, and use on a high-pile rug.
