Love vintage cat toys? Need a more sturdy toy (or one less likely to get lost under the couch)? This refillable wooden toy for cats is made from hand-turned, solid maple hardwood and comes complete with a bag of 100% pure natural catnip. Simply remove the top, pour in a little catnip, replace the top and watch your cat have fun. Originally designed in 1903 by Dr. A.C. Daniels himself, the first to market catnip and catnip toys to the household cat, who insisted cats just "can't let it alone."
