The loss of part of the cat's toes and his claws can be physically traumatic and psychologically demoralizing for your cherished family pet. Declawing a cat for owner convenience is never ethically justifiable. A declawed cat must forever be an indoor cat. Understanding the situation is half the battle. Below are some valuable lessons.
Scratching is a natural behaviour for cats.
This isn't exactly a revelation, since you probably have the evidence everywhere, in the tattered corners of your sofa, the shredded drapes, your frayed nerves. Though Kitty's natural propensity for scratching my not be big news, it is a fact that you'll need to take into account if you're to make any headway in winning the battle to keep her from scratching in places you consider undesirable. You can't keep your cat from scratching. What you can do is stop her from scratching those items you value and want to keep in their relatively pristine state. Translate this bit of wisdom to your dealings with cats and you'll avoid a good deal of futility and frustration.
