Quick answer: A scratch+hide combo from moving boxes takes about an hour: one box becomes the hideout, strips cut from a second box are packed into a tight corrugated block that forms the scratch wall, and the two are joined with paper tape. Put it near where your cat already naps, and replace the scratch block when it turns to fluff.
Moving leaves a stack of sturdy boxes and a cat that is often unsettled by new rooms and new smells. Turning two of those boxes into a place to hide and a place to scratch gives the cat both jobs in one spot, which is useful when you have not yet unpacked enough to set up proper furniture.
This is the one-hour weekend version, laid out by the clock. If you want more on which tape, inks and staples to strip off first, the cardboard tape, ink and staples safety guide covers it. The cardboard cat castle and box enrichment hub links related projects.
What You Need Before the Clock Starts
Gather everything first so the hour is spent building, not searching. You need two plain corrugated boxes, one about the size of a carry-on case and one smaller, a sharp utility knife with a fresh blade, a metal ruler, a pencil, brown paper tape or a starch-based paste, and a heavy book or two to press layers while you work.
Avoid boxes that held cleaning products, have printed glossy coatings or smell of anything strong. Cats explore with their noses first, and a box that smells of detergent is less likely to be used. Pull off any plastic tape you can reach; brown paper tape is a better choice for joints because it tears cleanly and does not leave sticky strips a cat can chew.
- Two plain corrugated boxes, one larger for the hideout
- Utility knife, metal ruler and pencil
- Brown paper tape or flour-and-water paste
- Heavy books for pressing
- An old towel or T-shirt for the floor of the hideout
Minutes 0 to 15: Shaping the Hideout
Stand the larger box on its side so the opening faces sideways. Fold the flaps inward and tape them flat so they form a double-thickness wall rather than loose edges. Cut a single doorway in one short side, about 15 centimetres wide and 18 centimetres high for an adult cat, with the bottom edge a few centimetres above the floor so bedding stays inside.
A second, smaller exit on the opposite side helps nervous cats, which often prefer a space they can leave by another route. Round off every corner of the cut openings with the knife so no sharp cardboard points stick out. Lay the old towel inside, folded to fit the floor.
International Cat Care notes that cats need places to disappear from view, and a box with a doorway placed against a wall meets that need straight away.
Minutes 15 to 40: Building the Scratch Wall
The scratch wall is where most of the time goes. Cut the smaller box into strips about 6 centimetres wide, cutting across the corrugation so the ridges run along the short edge of each strip. You need enough strips to make a block roughly 30 centimetres long once stacked on edge.
- Lay the strips on their edges, ridges facing up, packed tightly side by side.
- Wrap the block with a long strip of the box's outer wall, like a belt, and tape the ends together.
- Press the block under books for five minutes so the strips settle.
- Check the scratch face: the edges should be level and tight, with no loose strips that lift out.
Packing the strips tightly is what makes the block last. Loose strips pull out in the first session and leave a cat with nothing to grip. If the block feels soft, add two more strips and re-wrap.
Minutes 40 to 55: Joining the Scratch+Hide Combo
There are two common layouts. In the first, the scratch block is fixed upright against one outer side of the hideout, so the cat can stretch up it and then step inside. In the second, the block lies flat on top of the hideout, giving a scratch pad and a lookout in one. Upright suits cats that scratch furniture legs and door frames; flat suits cats that scratch rugs.
Fix the block with paper tape around the hideout's outer wall, or with a thin layer of flour-and-water paste and a few minutes under a book. Avoid hot glue on any surface a cat will claw or chew. Push and pull the finished piece hard: if the block wobbles, tape it again. Cats rely on a surface staying put; Ohio State's guidance is that a scratch post should be sturdy enough that it does not fall when used.
Checking the Build Before the Cat Gets It
Spend two minutes on a final check before introducing the piece. Run a hand around every edge of both doorways and the scratch block; anything that catches skin will catch a whisker or a paw. Lift the hideout by one corner and shake it gently: nothing should rattle loose. Press down on the roof with the weight you would expect from a cat jumping on top. If it caves in, add a folded cardboard brace inside along the long wall.
Look inside with a torch as well. Loose staples hide in the bottom seams of moving boxes, and a scrap of tape stuck to the floor can end up wrapped round a paw. Finally, sniff it. If the box still smells of the warehouse or the removal van, leave it in a ventilated room for an afternoon before the cat meets it.
Minutes 55 to 60: Placement and First Introduction
Place the combo where the cat already spends time, not in a spare corner. In a half-unpacked home, that is often near your bed, the sofa or the window the cat has claimed. Rub a little catnip or silvervine on the scratch face if your cat responds to it, and drop a treat just inside the doorway.
Then leave it alone. Many cats ignore a new object for a day before trying it. If yours has not used it after three days, try moving it closer to a spot it scratches already, or swap the layout from flat to upright. If children want to help, the kids-and-cats weekend scratch-hide build splits the job into tasks they can do safely.
Weekend Variations and When to Rebuild
Once the basic piece works, small changes keep it interesting. Add a second scratch block on the other side, cut a window in the roof for a cat that likes to peer out, or join two hideouts with a short tunnel made from a third box. Keep any variation solid enough not to collapse when the cat jumps on top.
Cardboard is a consumable. Replace the scratch block once the face is worn into a dip or sheds heavily, and recycle the whole piece if it gets wet, smells of urine or starts to sag. Keep an eye out for chewing as well: VCA notes that swallowed foreign material can block a cat's gut, so remove any piece being eaten rather than scratched.
If the box becomes a favourite, it is a good sign the cat wants a permanent scratch-and-rest spot. For bigger builds, see the one-hour cardboard castle from moving boxes, our notes on the best corrugated cardboard for a homemade scratcher and how many scratching posts a cat needs.
One-Hour Box Build Questions
How long does a cardboard scratch+hide combo last?
It depends on how hard your cat scratches. A tightly packed corrugated block often lasts several weeks before the face wears into a dip. The hideout itself can last months if it stays dry. Replace the scratch block when it sheds heavily, and recycle the whole box if it gets wet or soiled.
Is tape safe to use on a cat box hideout?
Brown paper tape is a safer choice than plastic packing tape because it tears cleanly and leaves no sticky strips. Remove as much plastic tape as you can before building, and keep all tape on outer surfaces away from the scratch face and doorway. Watch for chewing and remove any loose pieces your cat picks at.
Why won't my cat use the new box scratcher?
Many cats ignore new objects for a day or two. Placement is the most common problem, so move it to a spot your cat already rests or scratches. Try the scratch block upright instead of flat, or the other way around, and add a little catnip or silvervine if your cat responds to it.
What size doorway should a cat hideout have?
For an average adult cat, an opening about 15 centimetres wide and 18 centimetres high works well, with the bottom edge raised a few centimetres to keep bedding in. Larger cats may need more room. Round off cut corners and consider a second exit for nervous cats that prefer more than one way out.
