Catnip infused felted balls with recharging tin. Catnip infused Felted Balls have all the power of catnip without the mess of loose catnip. Fair Trade felted balls come fully charged with B Happy (Our custom catnip blend) and ready for play. When kitty seems to lose interest in the balls, return them to the tin to recharge. The Catnip pods in the bottom of the tin will magically recharge the balls in 24-48 hours. All orders include a variety of pastel ball color combinations.
