Thinking about it....
You can replace furniture. But you can't replace the cats claws

I have 3 cats with claws and they don not touch any of the furniture... I keep scratching posts round the house.
When my cats were kittens they did try and scratch the couch but keeping a spray bottle full of water helped keep them from sredding it. I didn't have to do this for very long and cats are smart enough to know what not to scratch....
