The toy is too fast for my cat, even at the lowest level, and when it touches the "Mauseschwanz" at this, it makes a loud noise and they knatriges startled. But I could imagine that the bolder cats do not care and do not bother me. So my conclusion, a good idea for a cat toy, but if there is slower and quieter would be good for my cat. For bolder and wilder cats it is already in a lovely independent gaming pleasure.
