The main body of the toy can rotate. The gravity system is designed on the central axis of the main body to prevent the toy from spinning too fast and making the cat lose interest. When the toy rotates for a few circles, the toy will stop slowly under the action of the gravity system and wait for the next swing of the cat. Two high-content cat Mint balls and a small cap are placed in the transparent part on the top of the toy When the toy rotates, the mint ball will jump irregularly, and the bell will make a weak sound. These two functions can effectively attract more cats' interest in playing.
