I was very lucky with all my furniture,from day one I never let her my living room
I have lots of expensive antiques that cost me a fortune to recover,so anytime she went inside that room,I would yell at her and chase her out. she learnt very quickly that room was off limits.
Occasionally when I am out and come home I do catch her sneeking out of the that room

However my settee and couch have no scratches on them.

she has an old couch in the basement that is pretty well out the door soon,she can claw at when she is purring.
Its funny how pets think they can fool you,Years ago when I had a dog, she was not allowed on the furniture, but sometimes I'd come home and she would be acting all innocent on the floor when we walked in,but when I touched the couch I could feel her body heat

She thought she was pulling one over on us jumping down quick when she heard us, but I knew better.
