The Catnip Cat Dancer interactive toy features the same lure as Cat Dancer, but it adds a catnip-loaded mouse to one end! The mouse is infused with 100 percent catnip oil in the molding process; the plastic casing will exude l'eau de catnip for up to four months. Catnip Cat Dancer is completely sealed in a two-sided blister package to keep the catnip vapors inside until time for use.
