Cat Scratching Posts: What Cats Actually Use

Most advice about scratching posts is taste. This is not, because somebody measured it.

A survey of 4,331 cat owners across 39 countries asked what their cats actually used, and the answers were specific enough to shop from:

• At least three feet tall (about 90 cm), whether that is a simple upright post or a multi-level cat tree.
• A narrower base beats a wider one. Posts with a base of three feet or less were used more than those five feet or wider.
• Sisal rope was the most preferred surface overall, but not universally: cats aged 10 to 14 preferred carpet, and kittens under eight weeks preferred S-shaped corrugated cardboard in a separate study.

Now go and look at what an entry-level scratching post in a supermarket actually measures. Most of them sit well under three feet.

That is the whole page in one paragraph: the commonest reason a cat ignores its post is that the post is too short to stretch on.

Why cats scratch, and the reason that changes where you put it

Three separate reasons, and blurring them is how people get the placement wrong.

Claw maintenance. Dragging the claws downward, called stropping, strips the worn outer sheath and exposes the sharp claw underneath. Kittens start at about five weeks old.

Territorial marking, and this is the one owners do not know. Scratching is documented communication: the visible mark and the shed claw husks are the signpost, and glands do sit between the pads of the paws. One honest footnote our paw pads guide details: no study has ever analyzed what those glands actually secrete, in any carnivore, so the "chemical message" everyone repeats is inference. A scratched surface is a signpost either way.

A full-body stretch, working the front legs and the spine, which is why the height matters.

Follow the second one through and the usual instinct is exactly backwards. If scratching is partly a social signal, then a post hidden in the spare room is a post the cat has less reason to use. It belongs where the household is.

Where to put it

• Next to whatever the cat is already scratching. Not across the room. Beside it.
• Near where the cat sleeps, because cats scratch on waking.
• In a social room, for the reason above.
• Somewhere it will not wobble. A post that shifts when a cat leans into it gets abandoned.

Getting the cat off the sofa

Here is where the evidence gets unusually clear, and unusually unflattering to the popular methods.

A controlled 2018 study tested the various redirection techniques people use. Only one had a statistically significant effect: physically placing the cat near the acceptable item. Not shouting, not spraying, not clapping.

And punishment did worse than nothing. A separate survey of 2,465 owners across the US and Canada found punishment associated with more reported scratching, not less.

So the method that works is dull and it works:

1. Put an acceptable surface immediately beside the unacceptable one. 2. Make the sofa arm less appealing temporarily, with a cover or double-sided tape. 3. Carry the cat over to the post, or lead it there. 4. Reward it when it uses the post. 5. Leave the post there. Move it later, if at all, by inches.

Declawing: what it is, and where it is legal

This needs saying plainly, because the name hides it. Declawing is not a nail trim. It is amputation of the last bone of each toe.

⚠️ You will read that declawing is banned across Canada. Until January 2027, that is not accurate, and Ontario is not a small exception.

One finding from that survey of 4,331 owners is worth putting beside this. Declawed cats in the sample had most often been declawed pre-emptively, to prevent damage that had not happened yet, rather than after a scratching problem. Which undercuts the last-resort framing the procedure is usually defended with.

The actual alternative is a nail trim every few weeks, and paying attention to the dewclaw, which never touches the ground and so never wears down on its own: more on that, and on the eighteen toes.

Cat trees, and whether the height is worth it

Vertical space is genuinely valuable to a cat, and more so in a household with more than one. Height gives a cat somewhere to be that is out of another cat's path, which is the single cheapest way to reduce the quiet competition that most owners never notice: the silent signs are covered here.

What you are paying for in a good tree is height, stability and a surface the cat likes. What you are often paying for in an expensive one is a shape that appeals to you.

Words, by market

Scratching post is universal. Scratcher is common in North America for the flat cardboard kind. Cat tree, cat condo and activity center all describe the tall multi-level thing, with cat tree the dominant search term everywhere we measured.

What to take away

• Three feet tall, minimum. It is the commonest reason a post gets ignored.
• A narrow base is used more than a wide one.
• Sisal wins overall; older cats lean to carpet, and small kittens to cardboard.
• Scratching is partly a territorial signal, so the post belongs in a social room, not a spare one.
• Beside the sofa, not across the room.
• Only one redirection method has significant evidence behind it: put the cat near the right thing. Punishment is associated with more scratching, not less.
• Declawing is amputation. Banned in the UK and Australia, banned in Canada except Ontario until January 2027, and legal in much of the US.
