My cat loves this so much my arms hurt
This is a very long, light feather toy made with a composite material that reminds me (frankly) of a car aerial – it's very flexible and easily manipulated. As others mention, the string is prone to getting tangled and does form knots occasionally. However, my cat (a ragdoll) _bloody loves it_. I get chirrupy meow noises periodically and have to play with him until he's contented, eats, and sleeps. Often I run out of energy before he does. It's a light, simple toy and flies through the air well.
