"Okay, this is a very very cool toy for the kitties. Both my younger and my older senior kitties love this. It has a lot of fun upsides, the best being that you can plug it in and not have to rely on batteries like most other cat toys (which is a major plus for this product). You can also set it to go on at regular intervals to keep the cats busy for hours (keep in mind that it does chirp and beep to attract the kitties, so I wouldn't recommend keeping this in an area of the house where you don't want to be distured - I keep it in the guest bedroom). One of my cats has even figured out how to turn it on with the button, which is funny to watch. Unfortunately he has also figured out how to reset the auto-on feature, or change it to run continuously - but this is only occasionally, so it's only a slight annoyance once in a while to reset the toy. The reason I take away a star is, as others have mentioned, the motor does become very loud after about a month of use. That, and my little Siamese who has very small paws has managed to remove the mouse from time to time (and run off with it - sometimes causing the toy to run continuously with no mouse on the track). Also, the ears do come off after a while when kitties try to catch the mouse (but you can buy replacement mice from the company). One of these units did malfunction on me, but after exchanging it, I've had no issues. Overall, even with the kinks, it's worth it to have this toy, and my kitties would be disappointed without it (they look forward to the chirping to hunt the mouse LOL)!"
