- Strong driver and versatile traversal: The cat ball can roll across ceramic tile, wood floors, low-pile rugs, and even high-pile carpet. It rarely gets stuck in corners, helping you entertain a high-energy cat for hours. Note: under the same working mode, balls roll more slowly on carpet than on wooden floor (see pic 2). - Important charging tips: Uses a 5V/1A adapter only. The cat ball runs about 5 minutes and then goes into sleep mode if your cat isn’t playing with it, and it will wake up again after about 2 hours to check if there is renewed interest. - Wake-up features: The toy activates via paw touch, and its motion-activated design helps keep cats engaged even when you’re not at home. - Three working modes: Fast mode (blue lights) rolls fast on high-pile rug; Slow mode (purple lights) moves well on floors; Interactive mode (yellow lights) only moves when nudged by your cat. Short-press to switch modes, and distinguish modes by light color (see pic 4). - Chirping bird toy: Realistic bird song to attract cats. The voice can be turned off by quickly pressing the button twice. Please wash fur off the gears occasionally. - The Game of the Braver - Chasing Running Mice: Recommended for adult cats or young cats with high energy, outgoing, lively, or naughty personalities. If your kitty fears a fast-rolling ball, set it to slow. Steps: 1) Choose slow mode. 2) DIY heavier tails on. 3) Use on high-pile carpet.
