Cat Scratching Posts: Height, Material and Placement
Written and checked with AI using the references below. This is not human expert review.
Quick answer
The best scratching post is at least 32 inches tall, will not wobble, and is covered in sisal rope, though some cats prefer cardboard or wood. Some cats prefer corrugated cardboard or wood instead, and a few prefer to scratch horizontally rather than vertically. Matching the post to your individual cat's observed habits matters more than any single feature.
Why Cats Scratch and What That Tells You About the Post
Scratching is not misbehavior. Cats scratch to remove the dead outer layer of their claws and expose sharper ones underneath. They also scratch to mark objects with scent glands in their paws, to stretch their muscles, and to show feelings like excitement or stress. Because scratching meets real physical and emotional needs, the goal is not to stop it but to redirect it to a surface you both accept.
Understanding the function helps you pick the right post. A cat stretching while scratching needs a tall surface. A cat marking territory needs something sturdy that holds scent. A cat sharpening claws needs a material that lets them dig in and pull. Sisal rope, corrugated cardboard, and wood all allow that grip; smooth surfaces do not.
The Three Attributes That Matter Most
Height: At Least 32 Inches
The Humane Society states that most cats prefer a scratching post that is at least 32 inches tall. That height lets a cat stretch fully upright, which is part of why cats are drawn to drapes and door frames. A post shorter than that forces a cat into a cramped posture, and many cats simply ignore it in favor of taller furniture.
As a practical check: stand your cat on its hind legs next to a tape measure. The post should reach at least to the top of its outstretched front paws, and ideally a few inches beyond.
Stability: No Wobble Allowed
Both the ASPCA and the Humane Society note that cats want a post that will not shift or collapse when used. A wobbly post startles a cat mid-scratch and teaches it to avoid the post. Stability comes from a wide, heavy base relative to the post’s height. Before buying, check that the base extends well beyond the post’s footprint. If you already own a post that tips, weighting the base or anchoring it to a wall can help.
Material: Sisal First, Then Observe Your Cat
Sisal rope is the most widely accepted surface. The Humane Society describes it as the preferred material for most cats. Sisal has a coarse texture that lets claws dig in and pull, which satisfies the claw-sharpening drive. However, individual cats vary. The ASPCA recommends offering posts made of cardboard, carpeting, wood, sisal, and upholstery to find what your cat prefers. Corrugated cardboard is a common second choice, and wood works well for cats that like to rake a rough grain.

Vertical, Horizontal, or Angled
Not every cat scratches vertically. The ASPCA notes that some cats prefer horizontal posts, some prefer vertical, and some prefer slanted surfaces. Some favor a vertical grain for raking downward; others prefer a horizontal grain for picking sideways. Watch where your cat currently scratches. A cat that claws the carpet is likely a horizontal scratcher. A cat that attacks the couch arm or a door frame is likely a vertical scratcher. The Humane Society suggests that if your cat prefers horizontal scratching, you can simply lay a vertical sisal post on its side or find a flat sisal pad.
Placement: Put the Post Where the Cat Already Wants to Scratch
Location is as important as the post itself. The Humane Society is direct on this point: place the post next to the object the cat currently scratches. If the cat targets the couch, the post goes beside the couch. If the cat scratches near the front door when you arrive home, the post goes near the door. Once the cat reliably uses the post, you can gradually move it a few inches at a time toward a less central spot if you prefer.
The ASPCA adds that once you know your cat’s preference, you should provide additional posts of that type in multiple locations around the home. Cats scratch in several spots, so one post in one room is rarely enough for a multi-room household.
How to Get Your Cat to Use the Post
Introducing the post correctly makes a real difference. The Humane Society recommends playing near the post so the cat interacts with it during play. Try a fishing-rod toy or laser pointer to get the cat moving around the post. Rubbing catnip on the post for the first several days also draws most cats to investigate it. The ASPCA suggests hanging toys from the post as an extra draw.
At the same time, make the previously scratched surfaces less appealing. Covering furniture with a tight-fitting sheet removes the texture cats want. Double-sided sticky tape on smaller surfaces works because cats dislike the sticky feeling on their paws. Once the cat consistently uses the post, you can remove the deterrents.

Two Common Mistakes to Avoid
Never Force the Cat’s Paws Onto the Post
Both the ASPCA and the Humane Society warn against carrying a cat to the post and rubbing its paws on the surface. This feels threatening to many cats and can create a stress response that causes them to avoid the post entirely, and sometimes to avoid the owner as well. Let the cat approach on its own terms, drawn by play or catnip.
Do Not Replace a Worn Post Too Soon
A shredded, frayed post looks like a problem but is actually a success. The ASPCA notes that cats prefer shredded and torn objects because they can really get their claws into the material. A used post also carries the cat’s own scent, which makes it more attractive, not less. Replace a post only when the base becomes structurally unsafe or the covering detaches and poses an entanglement risk.
Illustrative Example: Matching a Post to an Observed Cat
Suppose your cat regularly scratches the arm of a fabric sofa, pulling downward with both front paws while standing on the floor. That behavior tells you three things: the cat prefers a vertical surface, it likes a fabric-type texture it can dig into, and it needs enough height to stretch fully upright.
A reasonable starting choice would be a sisal-covered vertical post at least 32 inches tall with a wide, stable base, placed directly beside the sofa arm. Cover the sofa arm with a tight sheet for a short time. Rub catnip on the post for a few days. Use a wand toy to draw the cat toward the post during play. This is an example based on the behavioral guidance above; your cat’s actual response will vary.
If the cat ignores the sisal post but keeps returning to the sofa, try a post covered in a fabric closer to upholstery. You could also offer a cardboard scratcher in the same spot. The ASPCA recommends trying several surface types before deciding a cat will not use a post.
Frequently asked questions
How many scratching posts does one cat need?
The ASPCA recommends providing posts in multiple locations once you know your cat's preferred surface type. One post in one room is rarely enough for a cat that roams the whole house. A general starting point is one post near each area where the cat currently scratches, then add more as needed.
Can I make a scratching post at home instead of buying one?
Yes. The Humane Society notes that wood is a great scratching surface and that a handmade post or pad works well. The same rules apply: it must not wobble, and it must be large enough for a full stretch.
My cat ignores the post and keeps scratching the carpet. What should I try?
Carpet scratching usually signals a preference for horizontal scratching. The Humane Society suggests laying a vertical post on its side or finding a flat sisal pad. Place it directly over the spot on the carpet the cat targets, and use catnip or play to draw the cat to it.
Is catnip safe to use on a scratching post?
The ASPCA and Humane Society both recommend rubbing catnip on a new post to encourage investigation. Neither source flags safety concerns with this use. Not all cats respond to catnip, as the response is genetic, so if your cat shows no interest, try a wand toy near the post instead.
When should I replace a scratching post?
The ASPCA advises against replacing a post just because it looks worn or shredded. Cats prefer frayed surfaces and familiar scents. Replace a post only when the base becomes structurally unstable or the covering material detaches in a way that could tangle or injure the cat.
