This thing is UNREAL.
"This is the best cat toy I've ever bought! They absolutely love it! It gives hours of entertainment, not just for my cats, but also for my dog! I have a Pomeranian, and this has to be his favorite toy. He likes to jump into it, and walk around the house with the spring wrapped around his body, with the bell jangling and the ball bopping. He will chase the ball around in circles, WHILE the spring is on his body. It's hilarious. The toy has been very cleverly made, with a great deal of thought into what entertains cats - and dogs! From the ball on the end that bops around on the spring, to the feather and the bell, even down to the sparkly fabric attached to the entire spring that they like to chew on, every single piece provides endless play to these animals. I've bought five more just to have backups after they wreck it! It lasts for months though, with daily play. Totally an amazing toy for only eight bucks! And I don't even have to be involved!"
