this toy bounces unpredictably, spins its "tail" and is exciting for my kitties. i added a clump of organic catnip flowers for added interest. the only downside is that i found a few bits of the poly? flourescent "tail" that came off, but luckily my littles didnt eat them
I have bought hundreds of cat toys over the years and this is the best cat toy ever made! My cats love it and I am going to buy more.
