Scratching Is Not Bad Behaviour — It Is Cat Behaviour
One of the most frequent complaints among cat owners — particularly those who value their furniture — is scratching. Sofas, door frames, carpets, and curtains are commonly targeted, and the frustration this causes is entirely understandable. What is less understandable, and yet critically important, is that scratching is not misbehaviour. It is a deeply ingrained, biologically necessary behaviour that no amount of punishment will eliminate. The goal of any responsible management strategy is not to stop scratching — it is to redirect it.
Understanding the functions of scratching is the essential first step toward coexisting peacefully with a cat who scratches, as all cats do and always will.
Why Cats Scratch: The Four Core Functions
Claw Maintenance
The outermost layer of a cat's claw is a dead sheath that periodically needs to be shed to reveal the sharp new claw beneath. Scratching on a rough surface facilitates this process, keeping claws in optimal condition. Without adequate scratching opportunities, sheath removal is less efficient and claws can become overgrown, curved, and potentially painful — a genuine welfare concern.
Scent and Visual Marking
Cats possess scent glands between the digital pads of their paws. When they scratch a surface, they deposit a complex chemical signature that communicates their identity, reproductive status, and the timing of the deposit to other cats. The visual scratch marks serve the same territorial signalling function. This is why cats frequently scratch near doorways, windows, and other locations at the boundaries of their perceived territory.
Stretching and Physical Exercise
The act of scratching — reaching up or forward against resistance — provides a full-body stretch engaging the muscles of the back, shoulders, and forelegs. This is particularly important for indoor cats who have fewer opportunities for the whole-body movements that outdoor life naturally provides. You will often observe cats scratching immediately after waking, just as humans stretch after sleep.
Emotional Expression and Stress Relief
Scratching intensity frequently increases during periods of excitement, anticipation, or stress. Cats may scratch more when their owner arrives home, before feeding time, or when a new animal or person enters the household. This is a normal outlet for emotional arousal and should not be confused with aggression or deliberate destruction.
Declawing: Banned Across Most of the European Union
In many parts of the world, onychectomy — surgical removal of a cat's claws and the final bone of each digit — has historically been performed as a solution to unwanted scratching. Across the European Union and the United Kingdom, this procedure is now banned or restricted under animal welfare legislation in the vast majority of countries, including Germany, France, the Netherlands, Belgium, Spain, Finland, Sweden, Denmark, and Austria, among others.
The prohibition reflects a scientific consensus: declawing is not a cosmetic procedure. It is an amputation that causes acute post-operative pain, alters gait and posture permanently, removes the cat's primary means of defence, and is associated with long-term increases in biting behaviour, litter tray avoidance, and chronic pain. European veterinary associations and the European Society of Feline Medicine unanimously oppose the procedure except where medically necessary.
If you are ever advised to consider declawing by a practitioner — particularly if you are travelling-cat-europe-guide" title="Travelling Cat Europe Guide">Europe Guide">Europe Guide">travelling from outside the EU — seek a second opinion from a European-registered vet or a COAPE-accredited behaviourist who can suggest evidence-based alternatives.
Providing Appropriate Scratching Outlets
The most effective long-term solution to furniture scratching is giving your cat scratching surfaces it genuinely prefers. This requires understanding your individual cat's preferences, which vary significantly.
Vertical vs Horizontal Scratching Posts
Some cats prefer scratching vertically — reaching up against a tall post. Others prefer horizontal surfaces — scratching along a flat mat on the floor. Observe your cat's natural inclination: if it scratches the arm of your sofa (a vertical surface), it likely prefers vertical posts. If it targets your carpet or a doormat, horizontal scratchers are the better bet. Providing both types initially and observing which your cat chooses is the surest approach.
Material Matters
Sisal rope or sisal fabric is the material most cats find most satisfying for scratching, likely because its texture most closely mimics tree bark — the surface cats would naturally target outdoors. Cardboard is a highly popular alternative, particularly for cats who prefer horizontal scratching. Carpet-covered posts are less ideal, as they can blur the distinction between acceptable and unacceptable scratching surfaces in the cat's mind. Zooplus offers a comprehensive range of scratching posts, boards, and cat furniture in sisal and cardboard materials, with options from compact single posts to tall free-standing units and wall-mounted designs ideal for smaller European apartments.
Height and Stability Are Critical
A vertical scratching post must be tall enough for your cat to fully extend its body — for an average adult cat, this means a minimum height of sixty to seventy centimetres. Equally important is stability: a post that wobbles when scratched will be rejected immediately and not returned to. Choose heavy bases or wall-fixed designs to ensure your post remains steady during vigorous use.
Placement Is Everything
Position scratching posts near the furniture your cat is currently targeting — not hidden in a corner or spare room. Cats scratch in socially significant locations. Once your cat is reliably using the post, you can very gradually move it to a more convenient location over several weeks, shifting it just a few centimetres at a time. Place posts near sleeping areas as well, since cats frequently scratch immediately upon waking.
Humane Deterrents for Furniture Protection
While redirecting your cat to appropriate surfaces, you can make currently targeted furniture less appealing using humane deterrents.
- Double-sided sticky tape applied to targeted areas deters scratching through texture aversion — most cats strongly dislike the sensation of adhesive on their paws
- Loose covers of aluminium foil or plastic sheeting create a surface texture cats find unappealing
- Citrus-scented sprays applied to furniture can reduce interest, as most cats find citrus aroma aversive — always test on a small, inconspicuous area first
- Soft claw caps — small vinyl coverings glued over the claw tips — are a non-surgical alternative that reduces damage from scratching without eliminating the behaviour itself; these require regular replacement as claws grow
Deterrents work best when used alongside the provision of attractive alternatives, not in isolation. A cat deterred from a sofa will simply find another outlet — providing a clearly superior scratching option directs that energy appropriately.
When Scratching Increases Suddenly
A sudden escalation in scratching behaviour, particularly if accompanied by other changes such as altered appetite, increased hiding, or changes in litter tray use, warrants veterinary attention. Pain — particularly musculoskeletal discomfort — can alter scratching patterns. Environmental stressors such as a new pet, a house move, or changes in the owner's routine can also trigger increased scratching as a displacement and stress-relief behaviour.
A COAPE or IAABC-certified feline behaviourist can conduct a full environmental and behavioural assessment if scratching is part of a broader pattern of stress-related behaviour.

Scratching is a window into your cat's physical and emotional world. Approach it with curiosity rather than frustration, and the solutions become far clearer — and far more achievable.
