From the Field Freddy's Feather Wand

Freddy’s Feather Wand is an interactive entertaining all-natural toy that provides healthy exercise for cats. It's made with all-natural, biodegradable materials such as cork, hemp and wood— and natural, dye free duck feathers. 

The twirling mechanism (barrel swivel) is situated 1 foot up on the twine from the twirling feather playing part. This way, your cat never comes in direct contact with the small metal part (that is where cat’s teeth or claws can get stuck during intense playtime!).  You now can enjoy hours of safe playtime with your feline friend(s) without any worries!
