9 Best Cat Tree Replacement Posts (November 2026)
The best cat tree replacement posts include the TRIXIE Replacement Sisal Post for Cat Scratching for single-post repairs, the SIYIPURR 4PCS Cat Scratching Post Replacement for multi-post repairs, and the MUYG 2 Pcs Cat Scratching Post Replacement for two matching columns.
On this page (6 sections)
The best cat tree replacement posts are the TRIXIE 23.6-inch post for a single long column and SIYIPURR's 4-pack of 15.7-inch M8 posts for several repairs.
Measure your old post before choosing, because length, diameter and fastener size decide whether the replacement fits.
We compared the available lengths, diameters, pack sizes, materials and screw details.
The picks below cover single-column repairs, multi-post rebuilds, shorter sections and themed cactus or Gothic cat trees.
That range matters because a worn column is not always the same job.
One tall post may need a direct length match, while another tower may need several shorter sections at once.
For a broader introduction to choosing a scratching column, read our cat tree scratching post buying guide.
If the rope is worn but the column is still sound, our guide to the best sisal rope for cat scratching post may point to a smaller repair.
Use the measurements as your first filter, then use pack size and included hardware to narrow the choice.

TRIXIE Replacement Sisal Post for Cat Scratching: Best for single-post repairs
- 3.5 in diameter
- 23.6 in length
- Sisal-wrapped scratching surface
- Model 43993
The long 23.6-inch post suits a worn structural column when your cat tree uses the matching diameter and hardware. It is a focused replacement rather than a multi-pack.
Pros
- Longest single replacement here
- 3.5-inch diameter
- Made for indoor cat furniture
Cons
- Not a universal fit
- Only one post
The TRIXIE post is the best fit for a single long replacement column when your existing post measures 3.5 inches across and 23.6 inches long.
Its sisal-wrapped surface gives indoor cats a place to scratch, stretch and climb while you keep the rest of the furniture.
The 23.6-inch length is the main reason to choose it.
Many replacement posts here are 15.7 inches or shorter, so this one suits a taller structural section that needs a close length match.
That extra length can matter in daily use because a taller column gives a larger cat more room to stretch upward.
It can also help keep platforms at their original height without changing the frame layout.
TRIXIE identifies this model as 43993 and states a 3.5-inch by 23.6-inch size.
It is not a universal replacement, so remove the old post and check the diameter, bolt length and thread type before ordering.
This suits a focused repair where one column has worn down but the platforms and frame still feel solid.
For a multi-post repair, a 4-pack gives you more matching sections.
The trade-off is simple because you get one well matched post rather than spares for other columns.
SIYIPURR 4PCS Cat Scratching Post Replacement: Best for multi-post repairs
- 4 posts
- 15.7 in length
- M8 screws included
- Natural sisal rope
Four 15.7-inch posts make this a practical choice for rebuilding several worn columns or keeping spares. Confirm that your tower uses M8 screws before ordering.
Pros
- Four-post pack
- M8 screws included
- Natural sisal wrapping
Cons
- 15.7-inch length may not match taller trees
- M8 fit must be confirmed
The SIYIPURR 4-pack is best for several 15.7-inch repairs or for keeping matching spares.
Each post measures 15.7 inches and uses natural sisal rope, while M8 screws are included for towers built around that fastener size.
Four posts can refresh more than one scratching column in the same tree.
The pack also makes sense when several cats use the furniture and you want replacements available for future wear.
That spare-ready approach can save time later because a worn column can be swapped without waiting for a new order.
It also suits homes where scratching posts wear at different rates, which is common when cats favour one spot over others.
The key limit is fit.
Confirm that the old columns use M8 screws and that their diameter and length match the 15.7-inch posts before you buy.
Choose this pack for broad repair coverage.
If you only need two posts, the MUYG pair uses the same 15.7-inch length with a stated 3.1-inch diameter.
MUYG 2 Pcs Cat Scratching Post Replacement: Best for two matching columns
- 2 posts
- 15.7 x 3.1 in
- Natural jute hemp
- M8 screws
This 2-pack fits a repair that needs two matching 15.7-inch columns with M8 screw compatibility. Natural jute hemp covers the replacement poles.
Pros
- Two matching posts
- 3.1-inch diameter
- M8 screw fit
Cons
- Shorter than the TRIXIE post
- M8 fit must be confirmed
The MUYG 2-pack suits a tower that needs two matching 15.7-inch posts with a 3.1-inch diameter and M8 screws.
The poles use natural jute hemp and arrive as replacement sections rather than loose rope for a do-it-yourself wrap.
That ready-made format suits owners who want a clean swap without cutting, winding and securing rope by hand.
It can also keep the finish more even than a hand wrap, which helps when two columns sit side by side.
Two matching columns can keep a repaired tower visually consistent.
The stated size is more specific than a general standard fit, so measure your old posts instead of relying on the word standard.
MUYG also describes these as direct replacements for worn cat furniture columns.
The practical choice is simple because you select this pair when your existing hardware is M8 and the 15.7-inch by 3.1-inch dimensions line up.
For four repairs, the SIYIPURR 4-pack offers twice as many posts.
For a mixed-height tower, consider the OSPNIEEK set.
OSPNIEEK 4 PCS M8 Cat Scratching Post: Best for mixed-height refurbishing
- 2 posts at 15.7 in
- 2 posts at 7.9 in
- 2.76-inch diameter
- M8 screws and Allen key
The mixed-height pack helps when a cat tower has both long and short worn columns. It also includes an Allen key, but the 2.76-inch diameter must match your frame.
Pros
- Two lengths in one pack
- M8 screws included
- Allen key included
Cons
- Smaller diameter than several picks
- Requires M8 compatibility
The OSPNIEEK set is best for mixed-height tower refurbishment because it includes two 15.7-inch posts and two 7.9-inch posts.
All four have a 2.76-inch diameter, and M8 screws plus an Allen key are included.
This layout helps when a cat tree has both tall scratching columns and short sections near a platform.
That mix can suit towers that grew through add-ons or repairs over time and no longer use one uniform post size.
The included stud screws can also connect two pillars for a taller arrangement when your furniture supports that setup.
The natural sisal rope is wrapped around thickened cardboard tubes.
The useful buying check is the diameter and M8 fit, not the mixed pack alone.
Choose it when one tower needs two different replacement lengths.
If every worn section is the same height, a matching four-pack may be easier to plan and store.
FOBSME 2 Root Cat Scratching Post Replacement: Best for wider replacement poles
- 2 posts
- 13.78 in length
- 3.54-inch diameter
- M8 screws and Allen key
The 3.54-inch diameter makes this a strong match for a wider existing column. Its 13.78-inch length suits shorter replacement sections when the hardware is M8.
Pros
- Widest diameter here
- Two posts
- Allen key included
Cons
- Shorter than 15.7-inch options
- M8 fit must be confirmed
The FOBSME pair is the best choice for wider shorter columns, with two posts measuring 13.78 inches long and 3.54 inches across.
Each post uses natural sisal hemp and cardboard, while the set includes M8 screws and an Allen key.
The 3.54-inch diameter is the largest stated diameter in this group.
That makes it useful for a cat tree whose old columns are wider than the common 2.76-inch options.
A wider post can give a larger cat a fuller scratching surface and can feel more stable under a full stretch.
It can also suit a heavier frame where a narrow replacement would look out of proportion.
Measure the old post end to end before ordering.
A wider diameter will not solve a length mismatch, and M8 screws must still match the threaded parts in your tower.
Choose FOBSME when the 13.78-inch length and 3.54-inch diameter both line up.
For a 15.7-inch post with a smaller diameter, compare the MUYG or OSPNIEEK options.
SIYIPURR Cat Tree Replacement Post: Best for modular height changes
- 4 posts
- 9.84 in length
- 2.76-inch diameter
- M8 screws and wrench
These shorter posts suit repairs that need 9.84-inch sections or a modular height. The posts can connect into 19.7-inch or 39.4-inch arrangements with double-head screws.
Pros
- Four shorter posts
- Connectable lengths
- Wrench included
Cons
- Short sections may not replace one tall column
- M8 fit must be confirmed
The SIYIPURR 9.84-inch set is best for modular height changes and repairs that use shorter sections.
Four posts measure 9.84 inches by 2.76 inches, and the set includes M8 screws and a wrench.
The posts can be used individually or connected into 19.7-inch or 39.4-inch arrangements with double-head screws.
That gives you more layout options than a single fixed-length replacement, provided the frame and fasteners support the connection.
Modular sections can also suit a repair where only part of a taller column needs renewal.
They may help when a platform sits lower than expected and a full-length post would change the spacing.
This set also suits a wall, cage or wooden-base setup when the existing mounting plan matches.
Confirm the support and screw arrangement before changing the tower's height.
Choose it for short sections or a build that needs a modular layout.
For a direct 15.7-inch repair, select a post with that exact length.
SIYIPURR 2PCS Gothic Cat Tree Replacement Post: Best for Gothic cat trees
- 2 posts
- 15.7 in length
- 2.76-inch diameter
- M8 screws and wrench
This pair is shaped for a Gothic, Goth or coffin-style tower that needs 15.7-inch replacement columns. Check the 2.76-inch diameter and M8 hardware first.
Pros
- Themed-tower fit
- Two matching posts
- Wrench included
Cons
- Designed around a specific style
- M8 fit must be confirmed
The Gothic SIYIPURR pair is best for Gothic, Goth or coffin-style cat trees that need two 15.7-inch columns.
The posts measure 2.76 inches across and include M8 screws and a wrench.
The themed use is the main reason to choose this pair.
It helps preserve the look of a distinctive tower while replacing worn scratching surfaces.
That matters in a room where the cat tree is part of the decor rather than a plain utility item.
A matching repair can keep the style intact without replacing the whole frame.
Check the old columns carefully because the product still depends on a standard size match.
The 15.7-inch height, 2.76-inch diameter and M8 hardware all need to work with your frame.
Choose this set when the tower style matters as much as the repair.
For a cactus-themed tree, the cactus replacement pair below is the closer match.
SIYIPURR 4PCS Cat Scratching Post Replacement: Best for shorter four-post repairs
- 4 posts
- 11.8 in length
- 2.76-inch diameter
- M8 screws and wrench
Four 11.8-inch posts work well for a tower with several shorter worn columns. The natural sisal covering supports scratching while you reuse the existing frame.
Pros
- Four-post pack
- Shorter replacement length
- Wrench included
Cons
- Not suited to taller columns
- M8 fit must be confirmed
The SIYIPURR 11.8-inch 4-pack is best for several shorter columns.
Each of the four natural sisal posts measures 11.8 inches by 2.76 inches, and M8 screws plus a wrench are included.
This pack can refresh multiple short sections without cutting or wrapping loose rope.
It suits a tower where the worn posts are shorter than the common 15.7-inch replacements.
That shorter length can work well around low platforms, cat condos and compact towers where tall columns would crowd the layout.
It can also help when the original design used short posts as spacers rather than full scratching columns.
Measure the old columns before choosing it.
A four-pack does not help if your frame requires a taller post, and the M8 screw type still needs to match.
Choose it for a shorter four-post repair.
If you need taller 15.7-inch sections, the SIYIPURR 4-pack above offers that length.
SIYIPURR 2PCS Cactus Cat Tree Replacement Posts: Best for cactus-themed trees
- 2 posts
- 15.7 in length
- 2.76-inch diameter
- M8 screws and wrench
This pair refreshes a cactus or green cat tree when the old columns measure 15.7 inches and use M8 hardware. It keeps the themed furniture in service without replacing the whole frame.
Pros
- Made for cactus-themed trees
- Two matching posts
- Wrench included
Cons
- Themed design limits use cases
- M8 fit must be confirmed
The cactus SIYIPURR pair is best for cactus-themed or green cat trees with two worn 15.7-inch columns.
Each post measures 2.76 inches across and includes M8 screws and a wrench.
The themed design helps keep the furniture's original look while restoring its scratching sections.
The natural sisal surface gives cats a defined place to scratch instead of directing that behaviour toward nearby furniture.
That clear outlet can protect nearby upholstery, curtains and other items that sit close to the tree.
It also helps the tree keep its playful shape, which is often why owners chose that style in the first place.
Confirm the cactus tree uses M8 hardware and that the old columns measure 15.7 inches by 2.76 inches.
The style alone does not guarantee a fit.
Choose this pair when the theme is part of the reason you want to repair the tree.
For a plain tower, the MUYG or SIYIPURR options may give you a more direct match.
How to measure cat tree replacement posts before ordering
Measure the old column from end to end, including only the post itself. Record the diameter across the widest part, then inspect the bolts, threaded inserts and washers before removing anything permanently.
Use these checks:
- Remove the worn post if you can do so safely.
- Measure its length in inches.
- Measure the diameter across the column.
- Check the screw diameter, thread type and bolt length.
- Compare all four details with the replacement.
- Keep the original hardware nearby until the new post is installed.
A 15.7-inch post is not interchangeable with a 13.78-inch or 11.8-inch post just because the diameter looks similar. The same applies to M8 hardware, since the correct diameter still needs the correct thread and mounting depth.
If the tower needs a broader repair, our guide to cat tree replacement parts covers other worn sections. A new ladder can also help when climbing access is the damaged part, so see our best cat tree ladder picks.
Which replacement post length should you choose?
Choose the replacement whose length and diameter match the old column most closely.
The 23.6-inch TRIXIE post is the longest single option here, while the SIYIPURR modular posts are the shortest sections.
That gap shows why length should come before pack size in your decision.
A four-pack cannot fix a tower that needs one tall structural column.
Use a 15.7-inch post for many standard-height repairs, but do not treat that length as universal.
The 13.78-inch FOBSME pair, 11.8-inch SIYIPURR set and 9.84-inch modular posts solve different frame layouts.
Each length changes how platforms align and how much room a cat has to stretch.
A shorter post can leave a gap at the top if the frame was built for a taller section.
A longer post can also cause a problem because it may force the frame out of line.
Diameter matters for the same reason because the post needs to sit correctly in its mounting points.
A 3.54-inch post and a 2.76-inch post may use the same screw size but still suit different frames.
A mixed-height pack can be useful when one tower has several column sizes.
The OSPNIEEK set combines 15.7-inch and 7.9-inch posts, while the shorter SIYIPURR set uses four 11.8-inch sections.
That mix suits towers that have been repaired before or that combine low and high sections by design.
For a single uniform repair, a matching pack is usually simpler to plan.
Measure each worn column on its own because two posts on the same tree are not always identical.
Write down length, diameter, screw size and thread type before you compare options.
That short list will make the right choice much clearer than a general idea of standard size.
How to replace a worn cat tower post
Replace a worn cat tower post by removing the old hardware, checking the frame, matching the new post's holes and tightening the screws without forcing a mismatch.
Work on a stable surface and keep the tower supported during the repair.
Start by taking photos of the original assembly.
That step helps when washers, order of parts or platform orientation are easy to forget.
Remove the old column, compare the new length and diameter, then use the correct screws for the threaded parts.
Check the frame for cracks, stripped holes or loose inserts while the column is off.
Those checks matter because a new post cannot fix a damaged mounting point.
Fit the new post by hand first before you tighten anything fully.
That dry fit shows whether the holes line up and whether the platform will sit level.
Tighten the screws evenly and stop before you overtighten the post.
Excess force can damage the post or the frame, especially around threaded inserts.
After installation, check that the post does not wobble and that the platform sits level.
Recheck the fasteners after the tower has been used, especially if you connected sections to make a taller column.
Do not use a replacement that needs forced alignment.
A close visual match is not enough if the screw size, thread type or mounting depth differs.
If the fit feels wrong, stop and remeasure rather than pushing the parts together.
When should you replace the scratching surface instead?
Replace the rope instead of the whole column when the structural post is sound and only the outer wrap is worn.
That smaller repair can be enough when the core still feels firm and the fasteners hold well.
Our guide to the best horizontal cat scratcher can also help if your cat prefers a flat scratching angle.
Some cats will use a flat surface more than a vertical post, so the angle can matter as much as the material.
A full replacement post makes more sense when the column is damaged, the cardboard core is crushed or the fastener no longer holds securely.
In those cases a new wrap would cover the surface but would not restore strength or stability.
Matching the original post keeps the platforms and frame in their existing positions.
That can be important when the tower was designed around a specific column height.
For a style-focused update, see the best modern cat scratching post guide.
That route suits owners who want a new look as well as a fresh scratching surface.
If you are rebuilding the whole structure, our guide to the best wood cat tree covers a different starting point.
That choice makes more sense when several parts are worn or the frame no longer feels safe.
Use the condition of the core and hardware as your guide rather than the look of the rope alone.
Final verdict on the best cat tree replacement posts
Choose TRIXIE if you need one long 23.6-inch column and its 3.5-inch diameter and hardware match.
Choose SIYIPURR's 4-pack for several 15.7-inch M8 repairs, MUYG for two 15.7-inch columns, or OSPNIEEK when one tower needs both long and short sections.
For wider shorter posts, choose FOBSME.
Its 13.78-inch length and 3.54-inch diameter suit a frame built around that wider size.
For modular 9.84-inch sections, choose SIYIPURR's connectable set.
That option suits short repairs and builds that need to change height with linked sections.
The Gothic and cactus pairs are the clearest choices when the replacement also needs to suit a themed cat tree.
For the 11.8-inch SIYIPURR pack, choose it when several shorter columns need renewal.
In every case, measure length, diameter and fastener type before you order.
That check protects you from a post that looks right but does not fit the frame.

Frequently asked questions
How do I choose cat tree replacement posts?
Measure the old post from end to end, then check its diameter and fastener. Match the replacement's length, diameter, screw size and thread type before ordering.
A post that looks close can still fail to fit if the bolt or threaded insert differs.
Are cat tree replacement posts universal?
No. Cat tree replacement posts are not universal because towers use different lengths, diameters and fasteners.
Remove the worn column and measure it directly.
For M8 models, confirm the screw diameter and thread arrangement, then compare the replacement with your frame.
What does M8 mean on a cat tower replacement post?
M8 identifies an 8 mm screw diameter. An M8 cat tower replacement post still needs the correct length, thread type and mounting arrangement for your tower.
Check the old hardware instead of assuming every M8 post will fit.
Can I connect cat tree replacement posts?
Some cat tree replacement posts can connect with double-head screws, but only when the posts and frame support that setup. SIYIPURR's 9.84-inch posts are described as connectable into taller arrangements.
Confirm the required screw type before building a taller section.
Should I replace one scratching column or the whole cat tree?
Replace the worn column when the frame, platforms and fasteners remain sound. A matching post can restore the scratching area while you keep the rest of the tower.
Replace or repair more parts when several columns are damaged or the frame is loose.
