Mad Cat® Pouncin Pineapple Stacker™ has fun accents such as tempting feathers! Your cat can play with a single stacked toy or pull apart and play with the three separate toys! Mad Cat® Catnip contains pure North American catnip for a strong, aromatic fragrance that drives cats wild! Silvervine is a natural plant in the kiwi family that has two cat attractants compared to catnips one. Silvervine creates a similar reaction to catnip but affects more cats + has a longer play time!
