【Safer Silicone Material】This cat toy is made of silicone, making it safer and quieter to roll, with greater friction and durability. Its 43mm diameter better suits a cat's sense of control over its prey and avoids the fear caused by overly large toys. 【Automatic Rotation】This indoor cat toy automatically changes direction when it encounters walls, chairs, doors, etc., preventing it from getting stuck. It can rotate 360 degrees while emitting a blue LED light to attract your pet's attention, encouraging chasing and running – an ideal toy for pet exercise. 【Two Modes】This cat toy has a smart mode and a normal mode. A blue light for 3 seconds indicates smart mode, while a green light indicates normal mode. In smart mode, if not pressed for 5 minutes, the cat ball will automatically enter sleep mode; pressing it again activates it. In normal mode, the cat ball turns off automatically. 【Fun Interaction】This cat toy is suitable for indoor cats and dogs. Just press a button to start it automatically. It can stimulate the interest of cats and dogs, allowing your pet to play, entertain themselves, relieve stress, and no longer feel lonely. [Upgraded Type-C Charging] This cat toy uses upgraded Type-C charging, which is faster, more stable, and safer. Just open the silicone cover to charge. A flashing red indicator light indicates low battery. A flashing blue indicator light indicates charging. A solid green indicator light indicates the toy is fully charged. Please fully charge it before first use.
