Scratching is a fundamental feline behaviour that serves multiple functions. Providing appropriate outlets protects both cat welfare and household furnishings.
Scratching provision is a welfare fundamental that is frequently addressed inadequately — a single small post of soft material placed in an inconvenient location does not constitute appropriate provision for a species with strong scratching motivation. Cats denied adequate scratching surfaces do not stop wanting to scratch; they use whatever surface is available, typically furniture. The welfare problem of inappropriate scratching is often addressed through punishment or declawing rather than provision of what the cat actually needs. Declawing — still legal in some US states — involves amputation of the last bone of each digit and causes chronic pain and behavioural changes. Appropriate provision of adequate, well-placed scratching surfaces is a far more humane solution that serves the cat's needs while protecting the home environment.
