You're not alone. I have two of them.
They are slowly destroying my couch from the inside and outside. When a girlfriend comes over, the jealous Siamese will go under the couch and claw at her butt where she is sitting.
Then on the top side. I have hair all over the headrest, even between cleanings every two weeks (house cleaner). Then I have them sharpening their claws on the corners of couch and love seat.
This does not get into the yack on new carpeting, or claw marks on new drywall and paint upstairs, among other little 'treats' throughout the house.
