The toy uses a top shape as a whole, and the bottom is fixed by a suction cup, which can be adsorbed on a plane position at will. Three mint balls are built into the transparent shell on the top of the toy, which attracts cats' interest through the hollow design. The main body of the toy can also be rotated under the rotation of external force, and the cat funny rod made of two springs outside the main body is both a cat funny rod and a rotating booster rod. The unique gravity design prevents the cat from losing interest due to too fast rotation. It can be used by multiple cats at the same time.
