Review on Indoor Electronic Cat Toys With Mouse Tail And Catnip Ball, Battery-Powered Automated Interactive Toys For Exercising And Hunting, With Auto Shut Off - Perfect For Kitty Entertainment! by John Duffield

Our smart indoor cat loves this thing. The way it moves really activates his kitty brain. He catches the "animal” and drags the whole toy around - presumably to eat later. We took the annoying ball out and replaced it with a quieter one, and he enjoys chasing the noisy ball around the house (he won’t chase other things). Our less smart cat is not impressed with the toy or the ball, but she’s happy looking out the window all day whereas smart boy is not.
