Declawing - What You Should Know
Scratching is a natural instinct for cats and declawing causes a significant degree of privation with respect to satisfying the instinctive impulses to climb, chase, and exercise, by scratching. Cats simply enjoy scratching.
The sensible and humane solution to undesirable scratching is to modify the cat's conduct by making changes in the environment and direct the cat’s natural scratching behavior to an appropriate area (e.g., scratching post) rather than surgically altering the cat, thereby causing the animal pain, merely to fit the owner's lifestyle, aesthetics, or convenience.
The fact that many cats recover from the hideous experience of declawing without untoward effects, and even though they may not hold grudges, that doesn't seem sufficient justification for putting a family member through such a repugnant experience. In short, a declawed cat is a maimed, mutilated cat, and no excuse can justify the operation. Your cat should trust you, and depend upon you for protection. Don't betray that trust by declawing your cat.
