My cat loves em. He can be in the other room, and if I press it to produce such a soft sound I can barely hear it while holding it, he is in the room in an instant, looking for the red dot!
Like I said, maybe that explains why Clinton’s head was rolling around onstage...the guy was messing with her and shining it at the overhead!
Supposedly they’re really good for folks with limited mobility to let them have some quality kitty time.
