The suction cup base can be attached to the floor, the doors and windows, under the table, wherever you want to put it. There are 2 transparent capsules on the wind blade of the windmill which you can place luminous balls, bells and mint balls to attract your cat. When you flick it gently, the windmill will spin, making your cat reluctant to claw. There is a hair and face rubbing device in the middle. Can be a self-grooming aid for cats.
