The suction cup base allows you to attach the toy to any smooth surface - you can stick it on the kitchen floor, in the bathroom, on the walls or on furniture. Even on glass surfaces or upside down. If you add some water to the cup, the adhesive strength will increase.
To remove it, simply take it off - without damaging the surface it was attached to. With this option you can keep your cat busy and he will never get bored as he will find the toy in different, surprising places.
