The turf battle over furniture ended the 1st day placed Scat mat on couch and chair. I could have saved thousands of dollars worth of furniture if I got this produce sooner. The cats respect the mat and know exactly where it is but it did not hurt or traumatize them because they will lay right next to it. The cats also know as soon as it is not on the furniture. After a contact or 2 the mat will do the job even when not turned on. Well worth the cost
