- Strong driver that easily traverses ceramic tile, wood, low-pile, and high-pile carpet; rarely gets stuck in corners and keeps a high-energy cat entertained for hours. - Charging and idle behavior: uses a 5V/1A adapter. The cat ball runs about 5 minutes and then goes to sleep if not in use; it wakes up again after about 2 hours to check if your cat is interested. - Wake-up features: paw-tap activation and motion sensing keep the toy engaging when you’re away. - Three working modes: Fast mode (blue lights) rolls quickly on high-pile carpet; Slow mode (purple lights) moves well on floors; Interactive mode (yellow lights) only moves when nudged by your cat. Short press to switch modes; the light color indicates the current mode (see pic 4). - Chirping cat toy: realistic bird song to attract interest; volume can be turned off by pressing the button twice quickly. Periodically remove fur from gears for smooth operation. - The Game of the Braver - Chasing Running Mice: ideal for adult cats or young, high-energy, outgoing, lively, and naughty cats. If your kitty is scared of fast rolling, start with slow mode. Tips: 1) choose slow mode, 2) DIY heavier tails, 3) use on high-pile carpet. Note: In the same mode, ball speed is slower on carpet than on wooden floors (see pic 2).
