I have two cats, but one loves to play more than the other. Any time Georgie hears the bell ring on this toy she immediately alerts herself for play time.

Watch her play sped up 8x thanks to the Hyperlapse app from instagram. The only downside I find to this app, is that you must video within it. You cannot take a video and import it into the app to edit like you can in instagram. It's still pretty cool.
