Quick answer: To replace a scratch mat, measure the old one edge to edge, note how it is fixed and how thick it is, then buy woven sisal or rope a little larger. Hardware stores, marine chandlers, craft shops and carpet suppliers often stock natural sisal by the metre, so a local repair can be done the same day.
Scratch mats wear out unevenly. Most cats attack the same strip again and again, so one band turns to fluff while the rest of the panel still looks new. Throwing the whole scratcher away at that point wastes a perfectly good frame, and waiting for a branded spare can leave the cat without its favourite outlet for a week or more.
Think of this as a practical sisal rope buying guide plus a fitting manual. It covers the part people usually rush: measuring the old mat, matching its weave and fixing method, and finding material in local shops. It works whether the mat sits on a flat board, wraps a post or covers the face of a piece of furniture.
Why Fit Matters More Than Brand
A replacement mat that is slightly too small leaves a raw edge of board or glue that claws catch on. One that is too large bunches up, creating a ridge the cat may avoid. The material also needs to feel like the one your cat already chose. International Cat Care notes that each cat has its own preferences for the type of surface it likes to scratch, so switching from tight woven sisal to loose rope can put a cat off a spot it used daily.
That is why the measuring step comes first. Brand names matter far less than three numbers: width, height and thickness, plus how the old piece was attached.
How to Measure the Old Mat
Do this before you remove anything, while the mat is still flat and in place.
- Measure the visible width and height of the scratching area, edge to edge, in millimetres.
- Lift a corner and check whether the mat wraps round the board edge. If it does, add the wrap depth on every side.
- Measure thickness with a ruler pushed into an unworn section; most woven mats sit between 3 and 8 mm.
- Note the fixing: staples, glue, hook-and-loop strips, a frame or slots.
- Photograph the back and the edges so you can show the shop what you need.
Write these on your phone along with the board material. A cardboard insert, a plywood panel and a rope-wrapped post each call for a different replacement, and the photo saves a second trip.
| Mat type | What to measure | Typical local replacement |
|---|---|---|
| Flat woven panel | Width, height, wrap depth | Woven sisal rug or runner cut to size |
| Rope-wrapped post | Post diameter and wrapped height | 6 to 10 mm natural sisal rope |
| Slot-in insert | Slot width and insert thickness | Woven sisal glued to thin plywood |
| Hook-and-loop pad | Pad size and strip positions | Woven sisal with new adhesive strips |
Sisal Rope Buying Guide for Local Shops
Most replacement jobs use one of two materials: natural sisal rope for posts, or woven sisal sheet for flat panels. This short sisal rope buying guide covers what to ask for at a counter.
- Ask for natural, untreated sisal. Avoid oiled rope, which smells strongly and can leave residue on paws.
- Choose 6 to 8 mm rope for most posts; 10 mm suits large cats who scratch hard.
- Check the twist is tight. Loose, hairy rope sheds quickly.
- For flat panels, ask for a woven or bouclé sisal rug offcut rather than a seagrass or jute weave, which feels softer and wears faster.
- Buy roughly 15 percent more than your measurement to allow for trimming and errors.
Ohio State's Indoor Pet Initiative explains that most cats prefer rough material they can shred, and sisal is tough enough to stand up to repeated use. That toughness is the reason to stay with sisal rather than swapping to carpet just because carpet is easier to find.

Where to Find Sisal Near You
You rarely need a pet shop. Several types of local store carry suitable material, and calling ahead with your measurements saves time.
| Shop type | What they stock | What to check |
|---|---|---|
| Hardware or builders' merchant | Natural sisal rope on reels | Untreated, no oil smell |
| Marine chandlery | Heavier natural rope | Avoid tarred or treated lines |
| Carpet and rug retailer | Woven sisal offcuts and runners | Latex backing is fine; avoid loose weaves |
| Craft or upholstery shop | Thin woven sisal and spray adhesive | Small quantities, easy to cut |
| Garden centre | Sisal twine and rope | Twine is often too thin for posts |
Carpet shops are the most overlooked source. Many sell end-of-roll sisal pieces at a low price, and a single offcut can cover several panels. Ask whether they will cut a strip to width for you.
Fitting the Replacement Step by Step
Remove the old mat slowly. Pull staples with pliers and scrape away dried glue so the new piece sits flat. If the board underneath has softened or split, replace that too.
- Cut the new sisal 10 mm larger than your measurement on each side.
- Dry-fit it and mark the wrap points or slot edges.
- Fix the top edge first, then pull the mat taut downwards before fixing the bottom.
- Fold edges round the back and staple every 30 to 40 mm, or use a strong non-toxic glue.
- Trim loose fibres and check no staple heads stand proud on the front.
For rope-wrapped posts, start at the bottom with a staple inside the first turn, wrap tightly and glue every few turns. Our step-by-step piece on how to replace sisal or cardboard on a large DIY scratcher without rebuilding it shows the wrap method in detail, and the separate guide to replacing the scratch mat on a corner scratcher covers angled panels.
Keeping the Cat Interested After the Swap
A fresh mat smells unfamiliar and lacks the cat's own scent marks, which can make it less inviting for the first few days. Cats Protection points out that cats prefer to scratch objects that are sturdy, so make sure the repaired piece does not wobble at all once you put it back.
Return the scratcher to exactly the same position. Rub a little dried catnip or silver vine into the weave if your cat responds to it, and play near the panel with a wand toy so the cat drags its claws through the new surface. Most cats return to a well-placed spot within a week.
If the frame itself is past saving, compare the cost of a repair with a fresh build. Our breakdown of why replaceable refill pads beat disposable scratchers and the cost of ownership of replaceable sisal mats help with that decision.
When a Local Repair Is Not the Right Call
Some furniture uses a mat designed for a specific frame, with a curved face or hidden fixings. In those cases a generic offcut may never sit quite right, and the maker's own spare is the better option. Check the product page or the manual before cutting anything.
Carpet-covered towers are a separate job.

Replacement Scratch Mat FAQ
How do I measure a replacement scratch mat?
Measure the visible scratching area edge to edge, then lift a corner to see if the mat wraps round the board and add that depth on every side. Measure thickness on an unworn patch and note the fixing method. Add about 10 mm per side when cutting so you can trim to a clean edge.
Where can I buy sisal for a scratch mat locally?
Hardware stores and builders' merchants usually sell natural sisal rope on reels, and carpet retailers often have woven sisal offcuts. Marine chandleries and craft or upholstery shops are also worth calling. Ask for untreated, unoiled sisal and bring photos and measurements of the old mat.
What thickness of sisal rope is best for a cat post?
Six to eight millimetre natural sisal rope suits most cats and posts, giving a firm grip without being hard to wrap tightly. Large or heavy cats who scratch with real force may prefer ten millimetre rope. Whatever you pick, wrap it tightly and glue every few turns.
Will my cat use the new mat straight away?
Not always. A new mat lacks the cat's scent marks and can feel slightly different, so some cats ignore it for a few days. Put the scratcher back in its original spot, make sure it is completely stable and encourage scratching with play or a little catnip.
