Our Mad Cat? Rainbow Chaser Wand is a wand filled with hours of playtime for a feline and made from polyester with PP stuffing, colorful rope, bouncy, elastic string, and filled with a combination of premium catnip and silvervine in each of the three adorable soft plush toys for triple the fun. catnip and silvervine are pure and pesticide-free. The Rainbow Chaser Wand is ideal for hours of chasing and swatting for cats of all life stages. Some 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 prefer. This potent stimulant elicits a similar reaction to catnip and is both safe and fun.
