Quick answer: For a kitten's first scratcher, plain single-wall C-flute cardboard is easiest. Cut 5 cm strips across the flutes, stand about 50 of them on edge to make a 40 by 20 cm pad, and bond them with non-toxic PVA glue. That uses roughly 1 square metre of board, and the pad needs 24 hours to cure.
A kitten's first scratcher does not need to be big or expensive. A small cardboard pad on the floor gives it somewhere legitimate to dig its claws in during the weeks when it is learning what to scratch. Cardboard is soft, cheap, and satisfying under small claws, and you can make a pad from boxes already in the house.
This guide focuses on the material choices: which cardboard, how much, and what to glue it with. For bigger builds, our guide to the best corrugated cardboard for a large scratcher and the DIY scratcher hub cover adult-sized designs.
Why Cardboard Suits Young Kittens
Kittens have small, sharp claws and limited strength. Tight sisal can be too firm for them at first, while cardboard flutes give way just enough to feel rewarding. A floor pad also suits the way many kittens scratch, raking horizontally while they play.
Starting early matters. Kittens that learn to use a scratcher in their first weeks at home are less likely to settle on the sofa. International Cat Care's advice on scratching recommends offering suitable surfaces from the start, and Humane World for Animals suggests placing them where the kitten already plays.
Flute Sizes Compared
| Flute | Approx. thickness | Strips for 20 cm width | Board needed | Feel |
|---|---|---|---|---|
| C flute | 4 mm | 50 | About 1 m square | Soft, open, common in shipping boxes |
| B flute | 3 mm | About 67 | About 1.33 m square | Firmer, denser surface |
| E flute | 1.5 mm | Over 130 | Over 2.6 m square | Very fine, slow to build |
Each strip is 40 cm long and 5 cm wide, so it uses 200 square centimetres of board. Fifty C-flute strips therefore need 10,000 square centimetres, which is 1 square metre. B flute is thinner, so you need about a third more strips and board for the same width.
Avoid double-wall board for a kitten pad. It is harder to cut cleanly and the extra layer of liner makes the surface stiffer.
Choosing Safe Boxes
Use plain brown boxes without glossy coatings, plastic windows or heavy printing on the inside. Peel off all tape, labels and staples before cutting. Avoid boxes that held cleaning products, chemicals or food that has left grease stains, since kittens will chew the pad as well as scratch it.
If you are not sure what a box held, skip it. Brown shipping boxes from parcels are usually the simplest source.
Cutting Strips Across the Flutes
The scratching face should show the open ends of the flutes, so cut every strip across the corrugations rather than along them. Mark 5 cm lines with a ruler, then cut with a sharp utility knife against a metal straightedge on a cutting mat. A fresh blade gives clean edges and fewer torn flutes.
Cut a few extra strips. Some will crush near box folds, and those should be discarded rather than glued into the pad.
Gluing With Non-Toxic PVA
Use a water-based PVA wood or craft glue labelled non-toxic. Avoid hot glue, which leaves hard ridges kittens can chew, and solvent-based or spray adhesives. Run a thin line of glue along one face of each strip, press the next strip against it and keep the stack square against a board.
Clamp the finished pad lightly between two boards, or wrap it with string, and let it dry for 24 hours away from the kitten. Our page on tapes and adhesives for cat furniture goes into more detail on what to avoid.
A Simple Frame or None at All
A 40 by 20 by 5 cm pad can sit on the floor on its own. If the kitten pushes it around, glue it into a shallow tray made from a single-wall box lid, or add a non-slip mat underneath. A heavier frame is not needed until the cat is older and stronger.
Placing the Pad and Encouraging Use
Put the pad where the kitten plays and sleeps, and another beside any furniture it has started to scratch. Drag a wand toy across the surface so claws catch on the flutes. Praise or a small treat after each use helps the habit form.
If the kitten has already started on the sofa, read how to stop kitten scratching furniture for a fuller plan.
Reading What the Kitten Prefers
Watch the first few days of use closely. A kitten that rakes the pad flat on the floor and ignores your sofa is telling you it is a horizontal scratcher, at least for now. One that keeps reaching up the side of a chair or the curtains wants something upright. Our guide to vertical versus horizontal scratchers explains the signs in more detail.
Some kittens go for rugs and doormats instead. That usually means they like a looser, deeper texture than tightly packed cardboard. Try a pad made from C flute cut slightly wider, at 6 cm, so the flutes feel deeper, or lay a sisal mat next to the cardboard and see which wins. Our page on why cats scratch carpet covers this habit.
Making Spare Pads in One Session
Because pads wear out within weeks, it saves time to cut and glue three at once. One sheet from a large moving box often yields enough strips for two pads. Glue them on the same evening, label each with the date, and store the spares in a dry cupboard so they do not absorb moisture and go soft.
Rotating pads also helps keep the kitten interested. A fresh pad with crisp flutes is more inviting than a flattened one, and swapping it in the same spot keeps the habit tied to that location rather than to one particular pad. Put worn pads in the recycling bin rather than leaving them where the kitten can shred and swallow the loose fibres.
A cardboard pad also makes a good test before you commit to a bigger build. If the kitten uses it every day, you know cardboard suits it and can scale up; if not, try sisal before spending time on a larger cardboard scratcher.
When to Move Up From Cardboard
Cardboard pads wear quickly, often in two to six weeks of daily use. Replace the pad when the surface is flattened or shedding heavily. By around six months many cats want to stretch upright as well, which is the point to add a taller sisal scratcher.
A sofa-side scratcher for when the kitten grows Once your kitten starts stretching tall against the couch, the CozeCats Side Table gives it a sisal face at the sofa arm with a table top for you. Orders leave with next-day shipping, and there is a 30-day return window, with return shipping paid by the buyer.
If you prefer to keep building, our guide to a large scratcher that lasts scales up the same cardboard approach, and the CozeCats Side Table is an alternative when time is short.
Kitten Cardboard Scratcher Questions
What cardboard is best for a kitten scratcher?
Plain single-wall C-flute shipping cardboard is the easiest choice. Its 4 mm flutes are soft enough for small claws and easy to cut. Avoid glossy, printed or greasy boxes and double-wall board, and remove all tape, labels and staples before you cut the strips.
How much cardboard do I need for a 40 by 20 cm pad?
Each 40 by 5 cm strip uses 200 square centimetres. With C flute about 4 mm thick, you need about 50 strips to fill 20 cm, which is roughly 1 square metre of board. B flute is thinner, so plan on about 67 strips and 1.33 square metres.
Which glue is safe for bonding kitten scratcher strips?
Use a water-based PVA glue labelled non-toxic, applied in a thin line along each strip. Avoid hot glue, which leaves hard ridges, and solvent or spray adhesives. Clamp the pad lightly and let it dry for 24 hours away from the kitten before it is used.
Which direction should I cut the cardboard strips?
Cut across the corrugations so the scratching face shows the open ends of the flutes. That is the surface kittens dig into. Strips cut along the flutes give a flat liner surface that is far less satisfying and peels apart quickly once the kitten starts scratching it.
How often should I replace a kitten's cardboard pad?
Most pads last two to six weeks with daily use. Replace the pad once the surface is flattened or shedding lots of fibres. Keep making new ones until the kitten is around six months old, then add a taller sisal scratcher for upright stretching.
