Our Mad Cat? Big Cactus Kicker Catnip & Silvervine Cat Toy is a 10" Big Cactus that won't make a mess when a cat is kicking, pouncing, and wrestling. Filled with a super potent custom blend of catnip and non-toxic and all-natural silvervine for twice the cat attractants, and twice the fun! Plus crinkle sounds appeal to all of a cat's senses while they play. A super silly plush that entices cats who aren't affected by catnip. High-quality plush includes embroidery, crinkle paper, and ropes.
