Query: Works like a charm!

My kitties were starting to scratch on a few of my favorite pieces of furniture. As soon as I put these sticky strips on my furniture, their furniture scratching habits stopped immediately. I didn't expect it to work so well! The reason for 4 stars is because you do see the sticky strips, though they are clear. They would be less noticeable on light colored furniture. However, my furniture has been saved - mission accomplished. I did think about buying (or creating) double sided tape - thinking that might be cheaper, however, these are the perfect size and shape for what I need and are so easy to apply. It was much more convenient to get it done the right way!
