CAT DANCER Products Cat Chaser with Colorful Fleece, Interective Toy for Exercise (Pack of 6)

Does this has catnip in it? My kitten went crazy for a few hours while playing with it.

Does this attach on to the original cat dancer or something? I’m confused!

What is the rubber band loop looking part made of (cardboard, raffia)? I know one cat will eat it & need to be sure it's safe.

Is the cardboard part pretty sturdy?
