FIVE STARS! My cats loved this attachment. They tend not to like feather attachments as much as the smaller ones made by Litterboys, but this was a hit with all five cats. When spun through the air, the feathers move like a flying bird, and create a fluttering sound. The cats were mesmerized and could take their eyes off of it. Several leapt into the air to try to grab it. And, when caught, they looked as intense as the cat in the picture, above, which I got from Amazon's website. If you're looking to spice up your attachment toys, this one is a must have. You can get it on Amazon here: https://smile.amazon.com/gp/product/B01H482DNW/ref=ppx_yo_dt_b_asin_title_o03_s00?ie=UTF8&psc=1
