These are great to prevent cats from scratching. We recently bought an adjustable bed. The darn cats started to destroy under the bed bc it’s fabric. I was so mad and had to find something before they made it worse. I bought these. They’re easy to apply and stayed on well. After 3 months I replaced them with new ones on under and on the sides of the base for the bed. They were still sticking to the cloth material but the top part lost their stickiness bc of the sheets and blankets and touching them. They still didn’t scratch it even though it was no longer sticky.BEWARE: if you put this on a wood finish like a frame/trim or doorway, it will take off the finish!!! I haven’t tried it on a painted wall and don’t want to risk it. The trim was already ruined from before I bought my house from the previous owners cats scratching it. My cats started to scratch it too no matter how many scratch post I have (6) it’s just something they do… anyways o put this up and they stopped clawing everything that has this.When I first out it on the trim I didn’t put it on straight. I had to remove it and replace it. It was only on a few seconds and still removed the finish. Take your own risk.As for fabric I have noticed anything, not even sticky residue. It remains clean.
