Cats create problems, which is the definition of a cat. One common problem with cats is that they’ll scratch furniture, drapes, and anything else that you don’t want them to ruin.
One solution is to put scratching posts all over the place. The goal is to tempt the cat into scratching the post rather than any valuable furniture. Then again, cats will likely scratch both just to show that they don’t listen to humans no matter how much you care for them.
