A product called Feliway comes in a spray or a plug-in diffuser, and it's supposed to calm cats and deter them from scratching furniture, etc. The product ratings are very good. There is a similar product by a different brand, but I don't know how well it works. You can check out Petco or PetSmart's sites for ratings before you decide to buy it, if you decide to buy it, somewhere else for a cheaper price. I wish I had bought it before my cats destroyed my living room set.

We need a new couch. I think I'm going to have to try the spray to see if the cats will stop scratching before I can convince my husband to buy one. He won't buy a new couch if he thinks the cats are just going to shred it.

Having a couple of tall scratching posts around helps, too. Cats like to stretch out when they scratch for some reason.
