Quick answer: A scratch+hide combo from moving boxes is one sturdy box turned into a cave, with a pad of stacked corrugated cardboard strips glued to its lid as a scratch surface. With two or three leftover boxes, a craft knife and non-toxic glue, the whole build takes under an hour and fits beside a sofa in a small apartment.
After a move, most apartments have a stack of boxes and a cat exploring every one of them. Before they go to recycling, the best few can become a piece of cat furniture that does two jobs at once: somewhere to hide and somewhere to scratch.
Combining the two in one footprint suits small spaces. This build uses only boxes, a knife, a ruler and glue. For bigger multi-room designs, see our moving box cat castle, and for a version built around a sturdier frame, our scratch and hide combo guide.
Why a Scratch+Hide Combo Works in Small Spaces
Cats need both a retreat and a scratch outlet, and in an apartment floor space is tight. International Cat Care recommends giving cats high places to sit and places to disappear from view, and the same organisation lists cardboard boxes and paper bags among simple enrichment. A single box that offers a hideaway below and a scratch pad on top covers both in one spot.
Many cats also like to scratch after waking, so a scratch surface right on top of their resting place gets used naturally. Our news piece on why cats scratch after waking up explains the habit.
Materials and the One-Hour Plan
| Time | Task |
|---|---|
| 0 to 10 min | Choose boxes, strip tape, labels and staples |
| 10 to 20 min | Cut the entrance and reinforce the cave box |
| 20 to 45 min | Cut and glue corrugated strips into a scratch pad |
| 45 to 55 min | Fix the pad to the lid and add a liner |
| 55 to 60 min | Check for sharp edges and place it |
You need one strong box for the cave, about 40 x 30 x 30 cm, and one or two extra boxes for scratch strips. Use non-toxic water-based glue such as PVA. Our cardboard safety checklist lists what to remove before you start.
Step 1: Build the Cave
- Pick the sturdiest box, ideally double-wall cardboard.
- Tape the bottom flaps from the outside only.
- Cut an entrance on a short side, about 18 cm wide, leaving a 5 cm lip at the bottom.
- Fold the top flaps inward and glue them down to make a double-thickness lid.
- Add a folded towel or fleece inside as a removable liner.
A double-thickness lid matters because the scratch pad sits on top and the cat will stand and push on it.
Step 2: Make the Scratch Pad
- Cut the extra boxes into strips about 5 cm wide, across the corrugation so the ridges show on the cut edge.
- Make enough strips to cover the lid when stood on edge, usually 40 to 60.
- Glue the strips together side by side, edges up, in a tight block.
- Wrap the block with one long strip as a border and glue it.
- Leave it under a heavy book for 10 minutes while the glue grabs.
Cutting across the corrugation exposes the honeycomb edge that cats like to dig into. Ohio State's Indoor Pet Initiative notes that some cats prefer horizontal surfaces and recommends several scratching posts along the routes cats travel, so a flat pad on a box suits many cats well.
Step 3: Combine and Finish
Glue the scratch pad to the centre of the lid with a generous line of glue around its edge. Press it down and let it set. Trim any loose strips and run your hand around the entrance and edges to check for sharp points.
If the box feels light, put a heavy book or a bag of rice in a back corner inside, under the liner, so it does not slide when the cat scratches. A rubber mat underneath also stops sliding on hard floors.
Best Apartment Spots for the Box Combo
| Spot | Why it works |
|---|---|
| Beside the sofa arm | Puts the scratch pad where the cat already scratches |
| Near a window | Combines a lookout from the top with a hide below |
| By the bedroom door | Matches morning scratching after sleep |
| Avoid: busy hallway | Cat cannot rest in the hide |
| Avoid: next to the litter tray | Cats prefer to keep rest and toilet areas apart |
Try one spot for a week. If the cat uses the hide but not the pad, move it closer to the furniture it scratches. Our apartment scratch and hide layout shows a few more options.
Upkeep and Replacement
Cardboard scratch pads wear down, and that is part of the design. When the top is scooped out, cut a new pad and glue it on, or flip the old pad if both sides were glued well. Replace the whole box if it gets damp, crushed or smelly. Wash the liner weekly.
- Vacuum shreds every few days.
- Check the lid for sagging under the pad.
- Make a spare pad when you have new boxes.
- Recycle worn cardboard rather than keeping it.
Keeping spares means the cat is never without its scratch spot, which is what protects the sofa.
Variations for Different Cats
- Large cats: use a bigger box and a wider entrance, about 22 cm.
- Shy cats: add a fabric curtain over the entrance.
- Two cats: build two smaller combos rather than one shared one.
- Vertical scratchers: glue a tall strip pad to one side of the box instead of the lid.
- Seniors: keep the entrance lip low and skip the raised pad.

Common Mistakes to Avoid
A few errors turn a quick build into a short-lived one. Using a single-wall box for the cave is the most common: the lid sags as soon as the cat stands on the pad. Cutting strips along the corrugation is another, because it leaves smooth faces the cat cannot dig into. Leaving staples or tape inside, using strong-smelling glue or putting the combo next to the litter tray will also make many cats avoid it.
Finally, do not expect the cat to use it straight away. Drop a treat inside, drag a toy across the pad and give it a few days. Most cats investigate a new box within hours, but the scratch pad may take longer to become part of the routine.
Choosing Which Moving Boxes to Keep
Not every box from a move is worth using. The best candidates are clean, dry and rigid, with no oil or food stains and no strong smell from storage. Double-wall boxes used for books or kitchenware are ideal for the cave, because they hold their shape when a cat stands on the lid. Lighter single-wall boxes are fine for cutting into scratch strips.
Skip boxes that were stored in a damp garage or basement, any that held cleaning products, and boxes with heavy printing on the inside. Flatten the rest and keep two or three spare for replacement pads later.
Making It Look Tidy in a Living Room
Cardboard furniture can look temporary. Wrapping the cave sides in a plain cotton remnant or brown kraft paper hides box printing and makes the combo blend in beside a sofa. Keep the scratch pad itself bare so the cat can dig into the corrugated edges.
Moving Box Scratch and Hide FAQ
How do I make a cat scratcher and hideaway from moving boxes?
Turn one strong box into a cave by cutting an entrance and gluing the top flaps into a double lid. Cut other boxes into strips across the corrugation, glue them on edge into a block and fix it to the lid. Add a washable liner inside and check for sharp edges.
Is cardboard glue safe for cats?
Use a non-toxic, water-based glue such as PVA and let it dry fully before the cat uses the box. Avoid strong-smelling solvent adhesives and hot glue strings that can be pulled off. Remove all tape, staples and labels from the boxes before you start building.
How long does a cardboard scratch pad last?
It depends on how much your cat scratches, but pads usually wear down over weeks rather than months. When the surface is deeply scooped out, cut and glue on a new pad or flip it if both faces are usable. Replace the whole box if it gets damp or crushed.
Where should I put a scratch and hide box in a small apartment?
Next to the furniture your cat already scratches, such as the sofa arm, or near a window or bedroom door where it scratches after sleeping. Keep it away from busy walkways and the litter tray so the cat can rest undisturbed in the hide.
