Cute Cat

Indoor scratching
A natural behavior in cats is to periodically hook their front claws into suitable surfaces and pull backwards. This marks their territory and exercises their legs, in addition to cleaning and sharpening their claws. Indoor cats benefit from being provided with a scratching post so that they are less likely to use carpet or furniture which they can easily ruin. Commercial scratching posts typically are covered in carpeting or upholstery, but some authorities advise against this practice, as not making it clear to the cat which surfaces are permissible and which are not; they suggest using a plain wooden surface, or reversing the carpeting on the posts so that the rougher texture of the carpet backing is a more attractive alternative to the cat than the floor covering. Scratching posts made of sisal rope or corrugated cardboard are also common.
Although scratching can serve cats to keep their claws from growing excessively long, their nails can be trimmed if necessary. Another response to indoor scratching is onychectomy, commonly known as declawing. This is a surgical procedure to remove the claw and first bone of each digit of a cat's paws. Declawing is most commonly only performed on the front feet. A related procedure is tendonectomy, which involves cutting a tendon needed for cats to extend their claws. Declawing is a major surgical procedure and can produce pain, infections and permanent lameness.
