Pop n Play interactive cat toy It's not so expensive and easy to handle. Needs 4 big batteries and turns itself off after 15 minutes.
But be aware! The "birdsound" are nothing like birdssounds and go's in to a 15 minute loop. And the machine makes a lot of sound but if your not bothered by it than it is a good toy.
If there will be a V2.0 in the future that has either better and less frequent birdsounds or the machinery has been updated i would buy it
