Declawed? That doesn’t mean removing the claws, but the amputation of the last joint of the toes. Much kinder, if a new cat also figures out how to open closed doors, to replace the doorknobs.
Also, get or make a scratching post asap. Then, if the new cat is a kitten, teach it to use the post. I did that for our four kitten that I found 10 years ago. They have never tried or even indicated wanting to scratch the furniture.
