Quick answer: Start from the project, not the shop. A cardboard scratcher needs only a craft knife, steel ruler and glue. A sisal post adds a hand saw, drill and staple gun. A wall shelf adds a stud finder and spirit level. A small tower uses all of these plus clamps. Buy for your first project and borrow the rest.
Beginner tool lists tend to be long, and many first-time builders spend more on tools than on the cat furniture itself. A better approach is to choose your first project and buy only what it needs. Each later project then adds one or two tools.
This guide walks through four common builds in order of difficulty. For build ideas to try first, our DIY scratcher hub lists cardboard, sisal and wood projects that suit new makers.

Read down your project's column and that is your shopping list. Everything else can wait until you need it.
Project One: The Cardboard Pad
A flat cardboard scratcher is the gentlest start. You need a sharp craft knife with snap-off blades, a steel ruler that will not get nicked, a cutting mat or a scrap board, and PVA glue. That is all. Change the blade often: a dull blade crushes corrugated board instead of slicing it, and you end up pressing harder, which is when slips happen.
Cut with the ruler on the side you keep, so if the blade wanders it moves away from your fingers.
Project Two: A Sisal Post
A post brings in three new tools. A hand saw or jigsaw cuts the post and base to length. A cordless drill drives the screws that join them, and a countersink bit lets the screw heads sit flush so they never catch a paw. A staple gun fixes the start and end of the sisal rope, though glue does most of the holding.
For staples, 8 to 10 mm leg length is enough for rope ends. Longer staples can split thin wood. Our guide to cat furniture materials compares base woods that hold screws without splitting.
Project Three: A Wall Shelf
Shelves are where accuracy starts to matter. A stud finder locates the timber or metal studs behind the plaster, and a spirit level keeps the shelf flat so the cat does not slide off. A drill with wood bits, masonry bits or both, depending on your walls, completes the set.
Mark the stud centres in pencil, then drill a small pilot hole to confirm you have hit wood before you commit. Our wall shelves and window perches hub covers spacing, heights and bracket choices in detail.
Project Four: A Small Tower
A tower combines everything above and adds clamps. Two bar clamps hold parts square while glue sets and while you drive screws. They act as an extra pair of hands, which is especially useful when working alone. A jigsaw makes curved cut-outs for doorways in condo boxes.
After building, test for wobble before the cat climbs. Our non-wobbly cat tree stability test describes a simple push test, and our cat tree hub links to builds sized for beginners.
Borrow, Rent or Buy?
Tools you will use on every project, such as a drill, a craft knife and a level, are worth owning. Tools you need once, such as a large jigsaw for one curved cut, can often be borrowed from a friend, a tool library or a makerspace. Many hardware shops will also cut plywood to size for a small fee, which saves buying a circular saw.
Having the shop cut your boards also gives cleaner, straighter edges than most beginners manage at home, which makes joints tighter.
Fasteners and Consumables
- Wood screws in 30 mm and 50 mm lengths for joining 18 mm board
- Wall plugs or anchors matched to your wall type
- Staples, 8–10 mm
- PVA wood glue, water-based
- Sandpaper in 80 and 120 grit
- Masking tape for marking cut lines
Keep screws and staples in a lidded box. A dropped staple on the floor is a hazard to paws and to curious mouths.
Working Safely With a Cat in the Room
Cats are drawn to anything new, and a workbench covered in offcuts is very new. Shut the cat in another room while you cut, drill or use the staple gun. Noise and sudden movement can frighten it, and loose blades and screws are dangerous.
When you finish, sweep and vacuum the area before letting the cat back in. Check for stray staples with a magnet on a stick. ASPCA general cat care includes tips on keeping household hazards out of reach.
Glues and finishes give off fumes as they cure. Work with a window open and let finished pieces air out for a day or two before the cat uses them. EPA on VOCs and indoor air explains why water-based products are the better choice indoors.
Measuring and Marking: The Cheapest Tools That Matter Most
Most beginner mistakes are measuring mistakes. A 5 m tape measure with a locking button, a carpenter's pencil and a small try square cost little and prevent the classic error of a shelf that sits a few millimetres off level or a post base that is not square. Measure twice, mark once with a sharp line, and cut on the waste side of the line.
A try square also checks that a post stands at 90 degrees to its base before you drive the screws. If it leans even slightly, the post will rock when a cat pulls on it, and a rocking post is often refused. Clamp the post upright, check it with the square on two faces, then fix it.
For shelves, a 60 cm spirit level is long enough to span most brackets. Shorter levels can read level on one bracket while the shelf still tilts across the pair.
Protecting Yourself
Wear safety glasses when drilling and cutting, and a dust mask when sanding plywood. Hearing protection is worth having for jigsaw work. Keep the craft knife blade retracted between cuts. None of this is expensive, and all of it makes the first project more comfortable.
A Sensible First Purchase
If you want one starter bundle, buy a cordless drill/driver with a small bit set, a craft knife, a steel ruler, a spirit level and a tube of PVA glue. That covers a cardboard pad, a sisal post and most shelf brackets. Add a staple gun when you get to rope, and clamps when you start on a tower.
Spend on the drill: a cheap drill that stalls or strips screw heads makes every project harder. The rest of the kit can be basic.
Once the kit is together, our guide to replacing carpet on a cat tree and our plywood versus solid wood comparison are good next reads before a bigger build. If you prefer a no-tool option for a sofa, our couch protector table weekend project shows how far simple tools can go.
Beginner Tool Kit Questions by Project
What tools do I need to make a cardboard cat scratcher?
Only a sharp craft knife with snap-off blades, a steel ruler, a cutting mat or scrap board, and water-based PVA glue. Change the blade often so it slices the corrugated board cleanly. No power tools are needed for a flat cardboard pad.
Do I need a staple gun to build a sisal scratching post?
It helps. Glue does most of the holding, but a staple gun with 8 to 10 mm staples fixes the start and end of the sisal rope firmly. Longer staples can split thin wood, so match the staple length to the board.
What is the most important tool for beginner cat furniture?
A reliable cordless drill/driver. It drills pilot holes, drives screws for posts and shelves, and is used on almost every project except cardboard pads. A cheap drill that stalls or strips screw heads makes every build harder, so it is worth spending on.
Can I build a cat tower without a saw?
Yes, if you ask a hardware shop to cut your plywood to size. Many shops do this for a small fee, and the edges are often straighter than home cuts. You will still need a drill, clamps, a level and a staple gun to assemble and cover the tower.
How do I keep my cat safe while building furniture?
Keep the cat in another room while you cut, drill or staple. Afterwards, sweep and vacuum the area and run a magnet over the floor to catch stray staples and screws. Let glued or finished pieces air out for a day or two before the cat uses them.
