Quick answer: In the vertical post DIY vs buy decision, building usually saves money on materials but costs three to five hours and often produces a post that is too short or too light. Buying costs more up front but gives a heavy base and even sisal. Build if you have tools and offcuts; buy if stability, height or time matter most.
A vertical scratch post looks like the simplest cat project there is: a pole, a base and some rope. Plenty of people build one in an afternoon. Plenty of those posts end up in the garage within a month because the cat will not use them. The difference usually comes down to a few details that bought posts tend to get right.
This guide compares cost, time and durability honestly, then works through the problems that come up most often with homemade posts. For a full range of builds, see our DIY cat scratcher hub.
What a Good Vertical Post Needs
Whether you build or buy, the requirements are the same. Ohio State's Indoor Pet Initiative advises choosing a post high enough to let your cat get a good stretch and sturdy enough not to fall over during use. Cats Protection adds that a post should have a heavy, stable base so it does not wobble or topple.
International Cat Care is specific about height: posts should be as tall as your cat when standing on its hind legs at full stretch. For many adult cats, that means 80 cm or more of usable scratching surface, not counting the base.
- Scratch surface at least as tall as the cat at full stretch
- Base heavy and wide enough that the post cannot rock
- Tightly wound sisal rope or sisal fabric
- No exposed staples, nails or loose rope ends
Vertical Post DIY vs Buy: Cost Comparison for 2026
Material costs depend on what you already own. Prices below are rough ranges and vary by region and store.
| Item | DIY | Bought |
|---|---|---|
| Post and base | Low if using offcuts; moderate for new timber | Included |
| Sisal rope, 30 to 50 m | Moderate; the biggest single cost | Included |
| Fixings, glue | Low | Included |
| Tools | None if owned; otherwise a drill and saw | None |
| Your time | 3 to 5 hours | 15 minutes to assemble |
| Replacing worn sisal | Rewrap the same post | Depends on design; some have replaceable parts |
The money saved by building often disappears if you need to buy tools, or if the first attempt is unstable and needs a second base. Our comparison of a DIY scratcher side table versus buying applies the same maths to furniture-style pieces.
Time and Skill
A basic post takes three to five hours: cutting the base, fixing the post, winding and gluing rope, and letting glue cure. Winding sisal neatly is slower than most people expect, and gaps between turns are where claws catch and rope starts to unravel.
If you enjoy building and have the tools, that time is part of the fun. If you are building only to save money, consider whether the hours are worth more than the difference in price.
A middle route is to buy a ready-made base and pole and wrap it yourself. That removes the hardest part to get right, the stable joint, while keeping the cost of sisal and the satisfaction of finishing it at home.
Troubleshooting: The Post Wobbles
This is the most common failure with homemade posts, and the one most likely to put a cat off. Usually the base is too small or too light for the height. A rule of thumb is a base at least as wide as half the post's height, made from 18 mm plywood or heavier.
Fixes, in order: add a second layer of plywood under the base, screw the post through the base from below with a large bracket, add weight such as a paving slab under the base, or fix the post to a wall. Our guide to fixing a wobbly DIY scratcher walks through each option.
Troubleshooting: The Cat Ignores It
A sturdy, tall post can still be ignored if it is in the wrong place or the wrong orientation. Ohio State notes that cats that scratch chair legs or couch corners may prefer a vertical scratching post, so a post works best right next to those spots.
Cats Protection suggests placing a scratching post next to the area where your cat has been scratching and covering that area with thick, shiny plastic sheeting while the cat learns. Once the cat uses the post, you can gradually move it and remove the sheet.
If the cat prefers to scratch rugs and stairs, it may be a horizontal scratcher. Our guide on reading vertical or horizontal scratching preferences helps you check before building a second post. And if the cat still goes back to the sofa, our list of reasons a cat scratches the couch instead of the post covers the rest.
Troubleshooting: Sisal Frays or Unravels
Loose rope ends and gaps between turns are where fraying starts. Glue every few turns, push each turn tight against the last, and finish the end by tucking it under the final turns and stapling inside a groove where claws cannot reach.
Fraying is normal with heavy use. Replace the rope when strands hang loose or the post core shows through. Our guide to replacing sisal on a DIY scratcher without rebuilding shows how to rewrap a worn section only.
Choose untreated natural sisal. Our article on whether sisal is safe for cats explains what to avoid in dyes and oils.
Durability Over a Year
A well-built DIY post with good sisal can last as long as a bought one; the weak points are usually the base joint and the rope ends. Bought posts vary a lot. Cheap ones often use thin rope and light bases, while better ones have heavy bases and replaceable scratch sections.
Check either type monthly: push the top to test for wobble, look for loose strands, and tighten any fixings. A post that stays stable and tidy keeps getting used.
Signals That a Shop-Bought Post Is the Better Call
Buy if your cat is large, if you need a post taller than about 90 cm, if you do not have a drill and saw, or if a homemade post has already failed once. Buying also makes sense when the post has to sit in a living room and look like furniture rather than a project.
If the buy column wins For a spot beside the sofa, one option is the CozeCat Side Table, which combines a small table with a sisal scratch face on one side. Orders leave with next-day shipping, and returns are accepted within 30 days if your cat does not use it, with return shipping at your cost.
Many owners do both: build a post for a spare room and buy a scratch table for the living room sofa, where looks and stability matter most.
Choosing for Multi-Cat Homes
Ohio State notes that multi-cat households may need several scratching posts, both vertical and horizontal, located throughout the house. That changes the maths. Building three or four posts takes a long weekend; buying them adds up quickly. A mix, building simple posts for quieter rooms and buying one sturdy piece for the busiest spot, often works best.
Whatever you choose, place posts in different rooms rather than lining them up in one corner, so no cat has to compete for access.
DIY or Bought Post Questions
Is it cheaper to make a vertical scratching post?
Usually, if you already own the tools and have offcuts for the base. Sisal rope is the biggest material cost. Once you add tools, a second base after a wobbly first attempt, or the value of three to five hours of your time, the difference narrows. Buying makes more sense if you need height and stability quickly.
What post height suits a fully grown cat?
Tall enough for your cat to scratch at full stretch, which International Cat Care recommends. Measure your cat standing on its hind legs against a door frame. For many adult cats that means 80 cm or more of scratch surface above the base. A short post may be ignored once the cat is fully grown.
Why does my cat ignore the scratching post I made?
The usual reasons are that it wobbles, is too short, is in the wrong place or has the wrong orientation. Move it right next to the spot your cat already scratches, check it does not rock, and make sure it is tall enough. If your cat scratches rugs, try a horizontal pad instead.
How do I stop sisal rope unravelling on a DIY post?
Wind each turn tightly against the last, glue every few turns, and finish the rope end inside a groove or under the last turns where claws cannot reach. Replace the rope once strands hang loose or the core shows through. Untreated natural sisal is the best choice.
