Quick answer: The core cat DIY materials are sisal rope or fabric for scratching, corrugated cardboard for cheap pads, 18 mm plywood for frames, short cut-pile carpet, water-based PVA or wheat paste, and water-based finishes. Avoid jute oils, looped carpet, solvent glues and staples on scratch faces. Buy ready-made when durability or a replaceable surface matters.
Cat DIY sits in a busy market. For every material you can buy to make a scratcher, castle or toy, there is a finished product competing with it. Knowing what each material does, how long it lasts and where it can go wrong helps you decide what to make and what to buy.
This hub maps the main materials, the market products built from them, and the safety points that matter. It links out to our deeper guides on each topic. For general cat care and safety, the ASPCA's cat care pages and International Cat Care on cat-friendly homes are good starting points.
Scratching surfaces
| Material | Cat appeal | Durability | Notes |
|---|---|---|---|
| Sisal rope | High | High | Natural fibre; check it is untreated |
| Sisal fabric | High | Medium–high | Flat; easy to replace |
| Corrugated cardboard | High | Low | Cheap, messy, disposable |
| Cut-pile carpet | Medium | Medium | Avoid loops; may encourage rug scratching |
| Jute rope | Medium | Medium | Softer; some is oil-treated |
| Wood (bare) | Medium | High | Some cats love logs and posts |
Sisal is the most popular choice for durable scratchers. Our sisal scratcher guide, is sisal safe for cats and sisal fabric vs rope cover it in depth.
Frames and structures
Most DIY scratchers and side tables use 18 mm plywood or solid wood. Plywood is stable, flat and affordable; solid wood looks better but can warp and costs more. MDF is heavy and smooth but swells if wet and needs careful finishing. Cardboard is the material for castles and short-term projects.
Stability depends more on design than material: a wide, weighted base, glued and screwed joints, and a low centre of gravity. Our plywood vs solid wood guide compares the two main options, and cat furniture materials covers finishes and longevity.
Adhesives
| Adhesive | Use | Cat safety |
|---|---|---|
| Non-toxic PVA | Wood, cardboard, fabric | Safe once dry |
| Wheat or flour paste | Cardboard | Safe, free |
| Water-based contact adhesive | Carpet, sisal fabric | Let cure fully |
| Hot glue | Rope ends, quick joins | Remove strings; can be chewed |
| Solvent glue, spray adhesive | - | Avoid: fumes and VOCs |
Let glue cure fully and air the project before the cat uses it. The EPA explains how adhesives and finishes can release VOCs indoors.
Fasteners
Screws hold frames together. Staples and tacks hold fabric and carpet, but only where the cat cannot reach them: on the inside or back of a panel. Never put staples on a scratch face, as they work loose. For rope, many builders use glue plus a few small tacks at the ends, hidden under the wraps.
Finishes
Bare wood is fine for most cat furniture. If you finish it, use a water-based clear coat or a natural oil like food-safe hardwax oil, and let it cure for several days. Avoid strong solvent finishes, oil-based paint and varnish on areas the cat licks or sleeps on. Keep scratch faces unfinished.
Furniture tape and protectors
Double-sided furniture tape is a market product, not a DIY material, but it is often part of a DIY plan: tape on the sofa makes the old scratching spot unpleasant while the cat learns to use a new scratcher. Clear plastic shields and fabric covers do a similar job. These are short-term training tools rather than long-term fixes.
Our furniture protector tape pros and cons, tape vs shields vs scratcher and clear shields vs scratch guards guides compare the options. Always test tape on a hidden area first, as some adhesives mark leather and delicate fabrics.
Market products that compete with DIY
| DIY project | Market product | When buying wins |
|---|---|---|
| Cardboard scratch pad | Shop cardboard scratcher | Rarely; DIY is nearly free |
| Sisal post | Ready-made post | When stability and height matter |
| Scratcher side table | Factory-made side table | When time, finish or replaceable panels matter |
| Cardboard castle | Shop cardboard house | For a neater look |
| Couch cover | Fitted protectors | For a tailored fit |
Our DIY vs buying a scratcher side table and tape vs shields vs scratchers guides explore these trade-offs.
Materials to avoid
- Looped carpet (snags claws).
- Oil-treated or strongly scented rope.
- Solvent glues and spray adhesives.
- Staples or tacks on scratch faces.
- Glitter, sequins, small plastic parts on toys.
- Plastic bags and thin string.
- Treated or painted reclaimed wood of unknown origin.
If you suspect your cat has chewed or eaten something harmful, contact your vet or ASPCA Animal Poison Control.
Where to buy materials
Timber yards and DIY stores sell plywood and often cut it to size. Sisal rope and fabric come from craft shops, marine suppliers and online stores; check that it is untreated. Carpet shops give away offcuts. Cardboard is free from your recycling. For adhesives and finishes, look for water-based, low-VOC labels.
Buying from makers directly can also be worthwhile for finished products. Our how cat furniture is made and buying from a maker brand guides explain what to look for.
Lifespan of common materials
| Material | Typical life on a busy scratcher | Sign it needs replacing |
|---|---|---|
| Corrugated cardboard | Weeks to a few months | Deep troughs, shedding |
| Sisal rope | About a year or more | Fraying, loose wraps |
| Sisal fabric | Several months to a year | Bald patches, holes |
| Cut-pile carpet | Several months | Pulled tufts, bald patches |
| Plywood frame | Many years | Wobble, split joints |
These are rough ranges. A single gentle cat may make a sisal post last years; two energetic young cats can wear one out in months. Plan for the scratch surface to be a consumable and the frame to be the long-term part.
Cost per year, not cost per item
When comparing materials and market products, think in cost per year of use. Cardboard looks cheapest, but if you replace it every month the total adds up, and it is messy. Sisal costs more up front but lasts much longer. A frame with a replaceable panel costs more at the start, but each replacement is a small fraction of the price of a new scratcher. Our scratcher side table price breakdown guide shows this calculation.
Matching materials to your cat
Cats have preferences. Young cats and heavy scratchers need durable sisal and a solid frame. Older cats with stiff joints may prefer a horizontal cardboard pad or a lower, angled surface. Some cats love the bark-covered logs sold for scratching, others ignore them. If you are not sure, buy small amounts of two or three materials and see which your cat uses before committing to a big build.
- Kittens: cardboard and sisal, low and stable.
- Adult heavy scratchers: sisal rope on a tall, weighted post or side table.
- Senior cats: horizontal cardboard or a low, angled sisal board.
- Multi-cat homes: several surfaces in different rooms.
International Cat Care's guide to scratching on furniture and carpets explains why choice and placement matter so much.
Storing and reusing materials
Keep offcuts of sisal fabric and carpet for repairs. Store rope in a dry place, as damp sisal can go mouldy. Plywood offcuts make good test pieces for glue and finish, so you can check smell and adhesion before working on the real project. Flatten clean cardboard boxes and store them for the next scratch pad. Little bits of planning like this keep DIY costs low over the years.
Market products that pair well with DIY
Not everything has to be either DIY or bought. Many owners build the frame and buy the consumables: pre-cut sisal fabric panels, replacement cardboard inserts or ready-wrapped sisal posts that screw into a homemade base. Others buy a finished scratcher and add DIY touches, such as a cardboard pad at its foot or a carpet-covered step. Mixing the two keeps costs down while using factory-made parts where precision matters most. Before buying any part, check that its fixings and dimensions match what you plan to build, and keep the packaging until it fits.
Quick buying checklist
- Sisal: untreated, no strong oil or chemical smell.
- Plywood: 18 mm, flat, no delamination.
- Carpet: short cut-pile, firm backing, aired before use.
- Glue: non-toxic, water-based.
- Finish: water-based, low-VOC, for tops only.
- Fasteners: screws for frames, tacks hidden on panel backs.
Cat DIY materials FAQ
What is the best material for a cat scratcher?
