If your cat's inappropriate elimination persists, consult a veterinarian to determine if your cat has a urinary disorder. Contrary to popular opinion, cats do not claw all your belongings because they wish to annoy you. The clawing and scratching action is done for various reasons. Cats leave messages for other cats by the use of claw marks and hence use it as a way to mark their territory. Cat's also release their scent by clawing because the scent glands are located in the paw pads.
Scratching is also a way of keeping their claws healthy and sharp.
To provide your cat with an alternative to clawing your favorite couch, you can purchase cat trees and scratching posts at any pet store. Cat furniture covered in sisal, rope or fabric make excellent surfaces for your cats to work out their scratching needs. Some cats need some assistance understanding how fun their cat furniture really is. You can rub catnip over the cat furniture, or use catnip sprays sold in pet stores. Watch to see when your cat is about to claw your furniture, and gently move him or her over to the cat furniture and move their paws up and down along the furniture to teach them where to scratch.
