Few things frustrate cat owners more than coming home to find the corner of their couch shredded or their favorite armchair clawed to pieces. Destructive scratching is one of the most common complaints among cat owners and, unfortunately, one of the most common reasons cats are surrendered to shelters or subjected to declawing — a procedure that the American Association of Feline Practitioners strongly opposes due to the pain and behavioral problems it causes. But here is the thing most owners do not realize: scratching is not misbehavior. It is one of the most natural and essential behaviors a cat performs every day. Understanding why your cat scratches — and providing the right outlets — is the key to saving your furniture and keeping your cat happy.
Why Scratching Is Essential for Cats
Cats scratch for several overlapping reasons, all of which are deeply rooted in their biology. The first and most obvious purpose is claw maintenance. Scratching removes the dead outer sheath of the claw, revealing the sharper, healthier nail underneath. This is a normal part of a cat's grooming process — you may have found these translucent claw husks around your home, which is perfectly normal.
The second reason is territorial marking. Cats have scent glands called interdigital glands located between their toes. When a cat scratches a surface, these glands deposit pheromones that are invisible to humans but carry important territorial information for other cats. The visual marks left behind serve as an additional signal. According to the Cornell University College of Veterinary Medicine, scratching functions as both a visual and chemical communication tool that helps cats establish their presence and feel secure in their environment.
Scratching also serves as a form of physical exercise. The action engages the muscles of the forelimbs, shoulders, and spine, providing a full-body stretch that cats clearly find satisfying — many cats will seek out a scratching surface immediately after waking from a nap. Finally, scratching is a stress-relief mechanism. A 2024 study published in Frontiers in Veterinary Science surveyed more than 1,200 cat owners and found that stress was a significant factor driving excessive scratching, with cats in higher-stress environments engaging in more frequent and more destructive scratching behavior.
What Drives Excessive or Destructive Scratching
While all cats scratch, some cats scratch far more destructively than others. The 2024 Frontiers study identified several risk factors associated with increased scratching. Cats living in homes with young children scratched furniture significantly more often — likely because the presence of small children increases environmental stress for cats, who prefer predictable, quiet routines. Cats that were described by their owners as having aggressive or high-energy temperaments also showed higher levels of problematic scratching. Elevated nocturnal activity was another predictor, suggesting that cats who are under-stimulated during the day may redirect their pent-up energy into scratching at night.
Importantly, the study found that punishment — yelling, spraying water, or physically moving the cat — was not only ineffective but actually made scratching worse. Punishment increases stress, and since stress is a core driver of the behavior, punishing a cat for scratching creates a counterproductive cycle. Instead, the researchers recommended providing appropriate outlets and reducing environmental stressors as the most effective approach.
A lack of suitable scratching surfaces is another major factor. An earlier survey published in the Journal of Feline Medicine and Surgery found that many owners who complained about destructive scratching had either no scratching posts in the home, posts in the wrong locations, or posts made from materials their cats did not find appealing. When cats are not given scratching surfaces they enjoy using, they will find their own — and that usually means your sofa.
Choosing the Right Scratching Post
Not all scratching posts are created equal, and research has produced surprisingly specific recommendations about what cats prefer. A study published in the Journal of Feline Medicine and Surgery surveyed over 4,000 cat owners about their cats' scratching habits and preferences. The results were clear: sisal rope was the most popular substrate across nearly all age groups, with cats consistently choosing it over carpet, cardboard, and fabric. The only exception was geriatric cats aged ten to fourteen, who showed a preference for carpet — possibly because the softer texture is easier on aging joints.
Post design mattered as well. Cats preferred tall, vertical scratching surfaces that allowed them to fully extend their bodies while scratching. The study recommended posts that are at least three feet tall, with a stable base between one and three feet wide. Cat trees with two or more levels were especially popular, as they provided both scratching surfaces and elevated perching spots. Wobbly or short posts were used far less frequently — if a post topples over or does not allow a full stretch, most cats will ignore it.
The American Association of Feline Practitioners recommends providing multiple scratching surfaces throughout the home, in a variety of orientations. Some cats prefer vertical surfaces, while others prefer horizontal or angled scratchers. Offering a mix ensures that every cat in the household can find a surface that suits their preference. Cardboard scratchers, while less durable than sisal, are inexpensive and many cats find them irresistible — they make excellent secondary options.
Where to Place Scratching Posts
Placement is just as important as the post itself. Because scratching serves a territorial marking function, cats are most likely to scratch in socially significant areas — entryways, near windows, beside sleeping areas, and in rooms where the family spends the most time. Tucking a scratching post in a back corner of a spare room might look tidy, but your cat is unlikely to use it. The post needs to be where your cat already wants to scratch.
If your cat is targeting a specific piece of furniture, place the new scratching post directly next to it. Once the cat is consistently using the post instead, you can gradually move it — an inch or two per day — to a more convenient location. Covering the targeted furniture with a temporary deterrent, such as double-sided tape or aluminum foil, can discourage scratching on the wrong surface while the cat learns to prefer the post. The ASPCA notes that these aversion techniques should always be paired with an attractive alternative, not used alone.
For multi-cat households, providing enough scratching surfaces is especially important. Each cat needs to be able to mark territory without conflict. A general rule is to have at least one scratching surface per cat, plus one extra, distributed across different rooms in the home.
How to Redirect Scratching Behavior
Redirecting a cat's scratching is not about stopping the behavior — it is about channeling it to the right places. Start by making your scratching posts as attractive as possible. Sprinkling a small amount of dried catnip on the post or using a silver vine powder can draw your cat's attention to it. When your cat uses the post, offer a treat, gentle praise, or a brief play session to reinforce the behavior. Positive reinforcement is far more effective than punishment for shaping feline behavior.
The 2024 Frontiers study found that structured play sessions were one of the most effective strategies for reducing destructive scratching. Short, frequent play sessions that mimic hunting — using wand toys, feather teasers, or laser pointers followed by a tangible treat — help cats burn energy and reduce stress, addressing two of the root causes of excessive scratching. The researchers specifically noted that brief, varied play sessions were more effective than long, repetitive ones at maintaining a cat's interest.
Environmental enrichment also plays a role. Cats that have access to window perches, climbing shelves, hiding spots, and interactive toys tend to scratch less destructively because their overall stress levels are lower and their behavioral needs are being met. Creating a stimulating indoor environment gives your cat constructive outlets for the energy that might otherwise end up directed at your couch.
What Not to Do
Declawing, or onychectomy, involves amputating the last bone of each toe and is associated with chronic pain, gait changes, and increased biting behavior. It has been banned in many countries and several U.S. states and cities, and virtually every major veterinary organization advises against it. The American Association of Feline Practitioners, the American Animal Hospital Association, and the International Society of Feline Medicine all officially oppose declawing as a solution to scratching problems.
Soft nail caps — small vinyl covers that are glued onto a cat's claws — are a humane alternative for owners who need temporary protection for vulnerable furniture while training is underway. They need to be replaced every four to six weeks as the nails grow, and not all cats tolerate them, but they are painless and non-invasive. Regular nail trimming every two to three weeks can also reduce the damage caused by scratching without altering the behavior itself.
Above all, remember that scratching is not spite or disobedience. Your cat is not trying to ruin your furniture — they are maintaining their claws, marking their territory, stretching their muscles, and managing their stress. When you provide the right surfaces, in the right places, with the right encouragement, most cats will happily leave your furniture alone.
