When Hartz 100% Catnip comes out, nap time is officially over. Made with just a single ingredient, it's just what your kitty needs for a super-charged play session. All natural, and non-toxic to pets, catnip mimics the stimulation your furry friend's ancestors experience from tracking down prey in the wild. A pinch of this irresistible nip goes a long way. Sprinkle it on a scratcher, stuff inside a toy, or lightly dust your indoor cat's favorite lounging areas to spark a round of exercise.
