This playful wand features a custom silly straw handle that has the perfect amount of flex for interactive play. Super bouncy elastic string for maximum movement! This toy is great for active playtime, chasing, jumping, and pouncing. Cats LOVE catnip, but not all cats are affected by it. To solve this problem we developed our own unique blend of catnip and silvervine. Silvervine is a non-toxic, all natural catnip alternative that many cats actually prefer. This potent stimulant elicits a similar reaction to catnip, and is both safe and fun.
