Arrived quickly, looks good... However cats took one look at it and ran to hide when switched on. It makes alot of noise, which obviously frightens them. Also if they were not frightened, i do not think it would withstand vigrous play. the feather is on a flimsy piece of wire, so one good "catch" and it would break.
basically save money and just buy a regular toy and play with your cat. I have gone back to the mouse on the string
