Good idea but it can be dangerous
My large male ragdoll jumped on it as soon as it was dangling from the door frame, then he would not let it go, growling like a maniac. He actually took the suport off the frame by pulling from the cord, and it could have hit him hard at full tension. I had to cut the cord as he could have lost some teeth, so now it is a normal cat toy. I like the idea and he loves the toy, but I guess my cat is far too wild. He is taking the duck with him everywhere,though.
