Why do cats scratch? What this behaviour means and how to provide the right place

Scratching furniture, carpets or door frames can be frustrating for an owner, but from a cat's point of view it is not bad behaviour and certainly not an attempt to damage the home. Scratching is an innate feline behaviour that performs several important functions at the same time.

The aim should therefore not be to stop the cat from scratching. A much better approach is to provide a place that meets the cat's needs more effectively than a sofa or armchair. A properly designed cat tree can redirect natural scratching behaviour to an appropriate surface while also providing opportunities for stretching, climbing, observing the surroundings and resting.

Scratching is a natural need, not a bad habit

Cats scratch whether they live entirely indoors or have access to the outdoors. Outside, they may use tree trunks, wood and other surfaces that provide resistance. Inside the home, they simply choose what is available: the side of a sofa, a carpet, an armchair, a mattress or wooden furniture.

If a cat repeatedly scratches a particular object, it usually means that the location, material or position suits its needs. Instead of treating the behaviour itself as the problem, it is useful to ask why that particular place is so attractive.

What does a cat achieve by scratching?

Claw maintenance

Scratching helps a cat remove worn outer claw sheaths. For this reason, saying that cats simply “sharpen their claws” is an oversimplification. Scratching is part of normal claw maintenance.

Near a frequently used scratching area you may occasionally find a thin, translucent piece that looks like an empty claw. This is usually a naturally shed outer sheath rather than a broken claw.

Stretching the body

When scratching a vertical surface, many cats reach their front legs upwards, extend the back and push against the surface with considerable force. Scratching therefore also provides an opportunity for a full-body stretch.

A very short post may consequently be unattractive to a large adult cat even if the material itself is good. The scratching area should allow the cat to adopt a natural position without restricting its movement.

Marking the environment

Scratching also has a communication function. A cat leaves visible claw marks while also depositing its own scent from glands associated with the paws.

This helps explain why cats often choose prominent locations, pathways between important areas of the home or places close to entrances. From the cat's perspective, these locations are rarely random.

Why does a cat choose the sofa instead of the scratching post?

Simply owning a scratching post does not guarantee that the cat will regard it as the best scratching surface available. The sofa may win for several very practical reasons.

It is often located where both the family and the cat spend time. It is heavy and stable, its fabric provides resistance to the claws and its side may be tall enough to allow a comfortable stretch.

By comparison, a small scratching post placed in an unused corner, which wobbles when touched and offers only a short scratching area, may simply be less attractive.

What makes a good scratching area?

There is no single scratching surface that is perfect for every cat. However, several basic features are worth considering.

Stability

During vigorous scratching, a cat presses strongly against the surface and transfers part of its body weight onto it. The structure should not slide, tip or sway uncomfortably.

With larger structures, stability depends on more than the dimensions of the base. The arrangement of the posts and platforms, the quality of the connections and the proportions of the entire construction all matter. More detailed information is available in our guide on how to recognise a truly good cat tree.

Enough scratching length

A cat that prefers vertical scratching should be able to extend its front legs and stretch its body. When comparing products, look not only at the overall height of the structure but also at the actual length of the usable scratching surface.

A material that provides suitable resistance

Sisal rope is widely used, but some cats also enjoy sisal mats, cardboard, wood or other textured surfaces. The cat's existing scratching behaviour can provide useful clues about the material it prefers.

Vertical, horizontal or angled scratching?

Not all cats scratch in the same way. Some prefer a tall vertical post, others choose a carpet or horizontal pad, while some enjoy a surface positioned at an angle.

If a cat consistently scratches a carpet but completely ignores a vertical post, this is useful information rather than stubborn behaviour. Providing an additional horizontal scratching surface may be the better solution.

Differences may be even more noticeable in multi-cat homes, where each animal can prefer a different material, orientation and location.

Where should a scratching post be placed?

Location can be just as important as construction. A scratching post hidden in a room that the cat rarely visits may be much less appealing than a piece of furniture positioned along its daily route.

Useful locations include:

• areas where the cat already scratches;
• places close to favourite resting or sleeping spots;
• routes between important areas of the home;
• rooms where the cat and household members spend a lot of time.

Many cats scratch after waking. For this reason, a scratching surface located near a preferred sleeping place may receive far more use than the same post placed in an arbitrary location.

Does an outdoor cat also need a scratching area indoors?

A cat with outdoor access has many natural scratching opportunities, including trees and wooden structures. However, this does not mean that the need to scratch disappears whenever the cat comes indoors.

If the cat spends a significant part of the day or night inside, providing an appropriate indoor scratching surface remains useful and reduces the need to use household furnishings for this purpose.

In a multi-cat home, one scratching place may not be enough

In a home with several cats, scratching areas should be considered an important environmental resource. One large cat tree may be attractive, but it does not always replace several scratching options located in different areas.

One cat may prefer a post in the living room, another a pad beside its sleeping area, while a third chooses a scratching structure close to a window. Providing choice also means that every cat does not have to use exactly the same location.

What should you do if your cat scratches furniture?

Do not try to eliminate the need to scratch. It is more effective to redirect the behaviour towards a suitable surface.

If your cat repeatedly scratches one corner of the sofa, initially place the scratching surface directly beside that area. It should be stable and, where possible, offer a scratching orientation similar to the surface the cat selected for itself.

When the cat begins using it, reinforce the choice with play, calm praise or another reward the cat enjoys. There is no need to take the cat's paws and physically move them against the scratching surface.

If the scratching post continues to be ignored, reassess its stability, scratching length, material and location before assuming that the cat simply refuses to learn.

Does every cat need a large cat tree?

The need to scratch does not mean that every cat requires a huge multi-level structure. A well-designed simple scratching post or pad can provide an excellent scratching surface.

A larger cat tree, however, can offer additional functions. It may create vertical climbing space, observation points, platforms, hideaways, hammocks and sleeping areas. In this way it becomes not only a scratching surface but also part of the cat's wider living environment.

The best scratching solution is the one that matches the cat

Cats do not scratch without a reason. Scratching is a natural behaviour associated with claw maintenance, body stretching and communication through marking. When an appropriate surface is provided in the right location, most cats are highly motivated to use it.

Observe your own cat rather than choosing solely by appearance. Notice where it scratches, the position it adopts, which materials it selects and how far it reaches with its front legs.
