There are hundreds of cat scratching posts available in the UK, ranging from a few pounds for a carpet-covered tube to well over a hundred for a branded "cat tree." The range in quality is enormous and price is not a reliable guide — some of the most expensive products are also the most disposable, and some of the cheapest perform adequately for months before failing in the exact same way as everything else in the category.
We built Culm because we found the existing options frustrating — not just for sustainability reasons, but because the design logic of most scratching posts is simply poor. This guide is our honest attempt to explain what separates a good scratching post from a bad one, what questions to ask before buying, and where the category is genuinely improving.
We'll flag where Culm fits in. We'll also flag where it doesn't — or where it isn't the right choice yet.
This guide is written by Culm, which makes one of the products discussed below. We've tried to be fair — including to products we compete with — but you should factor in that context. We've focused on criteria rather than brand names, which we think is the more useful approach regardless of who's writing.
The five criteria that actually matter
A scratching post needs to allow a cat to fully extend — forelimbs, shoulders, the whole stretch. For most adult cats that means at least 90–100cm. Most budget posts are 45–65cm. That's not enough for an adult cat to scratch properly, which is why they ignore them.
If the post tips or wobbles when a cat leans into it, the cat stops using it. A heavy, wide base is essential. Look for quality structural materials rather than thin-walled hollow tubes. Note that bamboo culm is naturally hollow — its strength comes from its dense fibrous walls — which is quite different from the cheap hollow cardboard or plastic tubes that fail under load. A base that's proportionally large relative to post height is also essential.
Sisal and jute are consistently preferred by cats — they provide the right resistance for claw sheaths to catch and pull away. Carpet is second-rate and synthetic fabrics are the worst. Any surface should provide genuine resistance, not just feel rough.
The structural post should last years. Natural bamboo culm or solid hardwood are the best options. MDF is functional but degrades with moisture and can't be recycled. Thin-walled cardboard or cheap hollow tubes flex under load and deform over time — the issue is wall quality and thickness, not hollow versus solid. Bamboo culm is naturally hollow but derives considerable structural stiffness from its dense outer walls.
This is the criterion most guides ignore entirely. When the surface wears out — and it will — can you replace it without buying a whole new post? On most products the answer is no. This drives the disposable cycle that fills bins with perfectly functional structural components.
Where does it go when it's done? MDF, synthetic carpet, and plastic clips have no viable end-of-life route. Natural materials — bamboo, jute, untreated wood — can be composted or chipped. This matters more than the "eco" label on the box.
How the main types compare
Cat scratching products fall into a handful of categories. Here's how each performs against the criteria above.
Budget sisal posts (under £20)
Typically 45–65cm tall with an MDF or cardboard core, sisal rope wound and glued, and a weighted base. They perform adequately for small cats or kittens but the height is insufficient for most adults, the sisal bonds into the structure making it non-replaceable, and the whole unit goes to landfill when the surface wears through. At under £20, the price seems reasonable until you factor in that you're buying two or three per year.
Mid-range sisal posts (£20–£50)
Better materials and usually taller — 80–100cm is achievable in this range. The stability varies significantly; some have good weighted bases, others tip alarmingly under any lateral load. Surface is still typically bonded sisal, so replaceability remains zero. The structural post is often better quality than budget options — which makes it more frustrating that it still gets discarded with the surface.
Cat trees and towers (£40–£200+)
Floor-to-ceiling towers with multiple platforms, perches, and play features. The appeal is obvious and many cats genuinely love them. The sustainability problem is significant — large volumes of MDF, synthetic carpet, plastic-coated poles, and foam are all assembled in a way that makes end-of-life disposal essentially impossible as anything other than general waste. They're also the hardest category to replace piecemeal: when one platform's carpet wears through, the whole unit looks tatty, and most people replace the entire thing.
Cardboard scratchers
Corrugated cardboard pads or angled ramps. Cats often use them enthusiastically, the end-of-life story is better than most (cardboard can be recycled, though the compressed density of most scratchers makes this variable in practice), and the price is low. The lifespan is very short — weeks rather than months for an enthusiastic scratcher — and the format limits the stretch behaviour that makes scratching valuable for the cat.
Replaceable-surface posts
A small but growing category. Products where the scratching surface can be removed and replaced without replacing the structural components. Culm sits here. The design logic is sound — the post lasts indefinitely, only the surface is consumed — and it meaningfully reduces the waste generated over the product's working life. The category is small enough that options are limited, but it represents the direction the market should be moving.
Questions worth asking before you buy
Rather than recommending specific products — which would go stale quickly and inevitably reflects our own bias — here are the questions that reliably separate good purchases from ones you'll regret in six months.
Is it tall enough for my cat to fully extend? Measure your cat from nose to tail base while stretched. The post should comfortably exceed that length. If a product doesn't list its height prominently, treat that as a red flag.
What is the post actually made of? "Natural" on the label means nothing specific. Ask whether it's natural bamboo culm or solid hardwood, or MDF/particleboard. The difference in durability and end-of-life options is significant.
What happens when the surface wears out? Can you replace just the surface, or do you need to buy a whole new post? If the answer is the whole post, factor in the true cost over three to five years rather than the purchase price.
What is the surface material actually made of? Sisal or jute: good. Synthetic carpet or velvet: poor for durability and end-of-life. Smooth wood or plastic: cats typically won't use it.
How heavy is the base? A post that tips under lateral load is useless. If you can't find a weight or base dimension, look for customer reviews specifically mentioning stability.
"The true cost of a scratching post isn't the purchase price. It's the purchase price multiplied by how often you replace it. Factor that in and the maths changes considerably."
Where Culm fits — and where it doesn't
Culm is a good choice if you want a single high-quality post with a replaceable surface that you intend to keep long-term. The bamboo post is built to last, the jute sleeve is replaceable when worn, and the end-of-life story is significantly better than most competitors.
Culm is not the right choice if you want a multi-platform cat tree with perches and play features — that's not what we make, and won't be until we develop the full modular tower range. If you have a cat that strongly prefers horizontal scratching to vertical, a cardboard scratcher may suit them better regardless of post quality. And if budget is genuinely constrained, a mid-range sisal post bought once and used well is still meaningfully better than a cheap one replaced repeatedly.
The goal of this guide isn't to sell you Culm. It's to give you the information to make a purchase you won't regret — whatever that turns out to be.
Buying guides focus almost entirely on the purchase decision. The question nobody asks is: what happens in six months when the surface wears out? That question changes the analysis entirely. A £25 post replaced twice a year costs £50 annually and sends two posts to landfill. A £79.99 post with a £22 annual sleeve replacement costs less and sends nothing structural to landfill. The maths favours replaceability at almost any price point.
