I bought this because it is cute and my kitten needed more scratching areas. I didn't know it had a sound, but I like it! Also, the sound happens when my cat plays with it, whereas sometimes toy sounds are too hard to trigger. I can hear him playing with it in the other room which is nice because I know he's not causing trouble at that moment! It's on a doorknob now but it looks a bit too high for him at a young age, so I may put it on the floor and put the rope around a bed leg so it can be scratched without moving away, or I can attach another rope to it to make it longer.
Have a few cars at different life stages and they love this toy. Even months later it has held up well and it is still played with often. I recommend this over cardboard.
