Apartment-Friendly DIY Horizontal Scratcher Under $40

By Sebastian Frank, Founder of CozeCats · Last updated: November 5, 2026

Horizontal scratchers are among the cheapest cat projects you can build, but many DIY versions are glued blocks that end up in the bin once the top is shredded. In an apartment, you also want something quiet, stable on a hard floor and tidy enough to leave in the living room.

This build solves both problems with a frame that clamps loose cardboard strips in place. When the surface wears, you take the strips out, flip or replace them, and keep the frame.

Does Your Cat Want a Flat Scratcher?

Ohio State University's Indoor Pet Initiative notes that cats that scratch rugs and carpets may prefer a horizontal scratching post or mat. International Cat Care adds that kittens or senior cats may prefer softer surfaces such as large angled or horizontal cardboard scratchers. If your cat drags its claws across the rug, the stairs or the sofa base at floor level, a flat scratcher is a good first try.

Not sure which way your cat leans? Our guide to reading your cat's vertical or horizontal preference covers the signs.

Cost Breakdown for a DIY Horizontal Scratcher

Prices vary by store and region, so treat these as rough budget figures and check your local shop. The total assumes you already own a hand saw, a drill and a tape measure.

If you go over, skip the rods and use a fixed end board with a screwed wedge instead. That saves about $5 to $8.

Choosing and Cutting the Cardboard

Double-wall delivery boxes give a denser surface than thin cereal-box card. Our guide to the best corrugated cardboard for a homemade horizontal scratcher compares types, and the floor scratcher cardboard guide covers what cats seem to prefer underfoot.

• Remove all tape, labels and staples before cutting.
• Cut strips 5 cm wide, matching the depth of the frame, with the flutes running across the strip.
• Cut each strip to the inside width of the frame, 25 cm.
• Expect roughly 65 strips of double-wall board or 110 to 150 of single-wall board to fill a 45 cm bed.

A sharp utility knife and a metal ruler give clean edges. Change the blade often; dull blades crush the flutes.

Building the Frame

1. Cut two long sides at 50 cm and two short ends at 25 cm from the pine board.
2. Screw the long sides to one fixed end to make a U shape.
3. Screw the U to the plywood base.
4. Cut a loose end board that slides inside the U; this is the pressure plate.
5. Drill two holes through each long side, just behind where the pressure plate will sit when the bed is full, for the rods or bolts.
6. Sand all edges and corners round.
7. Fit pads under the base.

Leave the wood unfinished or use a plain oil. Our DIY cat scratcher hub covers other frame shapes if you want a curved or angled bed.

Packing the Pack Without Glue

Stand the strips on edge in the frame, pressing each one tight against the last. When the bed is full, push the pressure plate in hard, then slide the rods through behind it and fit the wing nuts. Tap two thin wooden wedges between the plate and the rods until no strip can be lifted out by hand. The strips hold each other in place, just as books do on a tight shelf.

Glue-free packing is what makes the scratcher refillable. It also means the only material your cat touches is plain cardboard.

Keeping It Quiet and Steady on Hard Floors

Apartment floors carry noise to neighbours, and a scratcher that skids across tiles is one a cat soon ignores. Cats Protection notes that cats prefer to scratch objects that are sturdy, giving them a good grip to dig their claws in. A few details help:

• Use four pads, one at each corner, rather than two strips.
• Choose rubber pads for tile and laminate, felt for rugs.
• Keep the pack tight; loose strips rattle and shift under a pulling cat.
• Make the base a little wider than the frame so the scratcher cannot tip when a cat pulls on one edge.
• Build and sand on a balcony or in a shared workshop, not late at night.

Mistakes That Shorten Its Life

• Flutes running along the strip instead of across it, which makes the surface peel.
• Strips cut wider than the frame depth, so they bow and wobble.
• A gap at one side of the pack, which lets strips lean and fall.
• Gluing the first layer to the base, which stops you flipping it later.

Each of these is easy to fix on the next refill, which is the point of a frame you keep.

Where to Put It in an Apartment

Ohio State notes that cats often scratch prominent objects near sleeping areas and room entrances. Cats Protection suggests placing a scratching post next to the area where they've been scratching, choosing one with a heavy, stable base, and putting one near the cat's bed because cats often scratch and stretch when they wake up.

• Put it directly in front of the rug corner or sofa base your cat has been using.
• Choose a hard floor or flat rug, so the pads grip.
• Place a small mat around it to catch cardboard crumbs.
• If you have two cats, Cats Protection advises each cat should have its own scratching post in a different place.

Refilling and Flipping

When the top surface is shredded, knock out the wedges, lift the pack out and flip every strip so the clean edge faces up. When both edges are worn, replace the strips with fresh cuts from your next delivery box. Our guide to why replaceable refill pads beat disposable scratchers explains the long-term saving, and this step-by-step large cardboard scratcher scales the idea up.

Prefer a Scratcher That Is Also Furniture?

A floor scratcher solves rug scratching but takes up floor space. If you also need a place to set a lamp or a drink, a scratch surface built into a side table, such as the CozeCat Side Table, combines the two in one footprint.

DIY Horizontal Scratcher Questions

How much does a DIY horizontal scratcher cost?

Using rough mid-range prices, the pine board, plywood base, screws, two rods with wing nuts and furniture pads come to about $26 to $41, with cardboard free from delivery boxes. That assumes you own a saw and a drill. Using a screwed wedge instead of rods saves about $5 to $8.

How do you make a cardboard scratcher refillable?

Pack on-edge cardboard strips tightly in a wooden frame and lock them with a sliding pressure plate, two rods and thin wedges, rather than gluing them. When the top wears, remove the wedges, flip the strips to the clean edge and refill later with fresh strips cut from delivery boxes.

Do cats prefer horizontal or vertical scratchers?

It varies by cat. Ohio State's Indoor Pet Initiative notes that cats that scratch rugs and carpets may prefer horizontal posts or mats, and International Cat Care says kittens and senior cats may prefer softer surfaces such as horizontal cardboard. Watch where your cat scratches now and match it.

Where should a horizontal scratcher go?

Put it right in front of the rug or sofa area your cat already scratches, as Cats Protection suggests, or near its bed, because cats often scratch on waking. Ohio State also points to room entrances. A hard floor or flat rug with grip pads underneath keeps it from sliding.
