From the Field Freddy's Feather Wand

Freddy’s Feather Wand is an interactive entertaining all-natural toy that provides healthy exercise for cats. Since it's made with all-natural, biodegradable materials such as cork, hemp, wood, and dye-free duck feathers, this wand toy is purrfect for playing, and will fully decompose when it's (eventually) time to be trashed.
