"The concept of this product is good, as cats do not like the sticky sensation HOWEVER the strips(double sided tape) in my opinion are far too thin both in width and thickness, plus the, "Sticky" doesn't seem strong or long lasting enough to do much good. Like another reviewer suggested you would need quite a few packages to cover the entire area and that is just not feasible. Even so after covering the entire area I found my cat was still able to scratch through the product with no problem. I also found if you leave the strips in place for very long they can leave a sticky residue on the furniture, which is almost impossible to remove, either that or they come off in tiny bits and pieces when trying to remove/replace them. As directed you also have to be careful about the fabric you are placing the strips on, as I found more fragile fabrics were more likely to be at risk. I have 4 cats, yet only 1 is a scratcher and he actually scratched through the strips in record time then tried to eat the pieces which fell off, while my furniture still has some sticky residue I simply cannot get off. If you have a very mild scratcher you might find these helpful or if your cat has only one tiny area they scratch, but for me they didn't work at all."
