We have a young enough cat, very fond of playing, has intelligence, wears objects and asks her to throw them, then again brings and so you can kill the whole day or night. In short, it acts like a dog :) but this toy did not come to her, she immediately began to hunt not for a fluffy ball, And behind the white plastic design with the eye, that is, she laughed, if she cut out this eye, then the ball will not be mocked like that. It is confused by the sound that this toy makes, it is distracted by it and begins to attack the body with a black eye, but if the device is turned off, it will not be be But our cat is more an exception, so it's difficult to correctly evaluate this device.
