All four of my cats have their claws too and I won't have them declawed, even though they do like to scratch where they are not supposed to. When I got my first cat as a kitten, she took a liking to the arms on my leather couch. It didn't take but a few times and the arms were ruined. I tried to break her from that and never could. I put a old bedspread over the couch, thinking that might help, but she would just claw underneath the bedspread.
Got cat number 2, he liked the couch and the recliner. Now the side of the recliner is all torn up from cat scratches. I even brought a piece of firewood into the house thinking that they would scratch on that. They looked at it like they didn't know what it was and never did use it to scratch on.
Cat number 3, also likes the side of the recliner. Now the entire side of the chair is totally in shreds.
Got husband. He made a huge cat scratch post for the cats. Which now includes cat number 4. We have heard some scratching noises on it, but they still like to scratch in places that they shouldn't.
Maybe one day I'll get some new furniture, but if not, it's okay. It's just furniture and I love my cats more than any piece of furniture on this planet.
