Quick answer: A DIY kitten playhouse from moving boxes takes under an hour: strip tape and labels, cut two kitten-sized doorways and a window, join two boxes with paper tape or plain flour paste, and line the floor with a towel. Use the rest of the weekend to add a tunnel and a second level, and check the boxes daily for chewed pieces.
Moving boxes are perfect for a kitten playhouse: sturdy, free and the right size for a small cat to hide, pounce and nap in. A basic house takes less than an hour. The weekend gives you time to watch how your kitten uses it and to add the bits it enjoys most.
This plan splits the work into a short Saturday build and a Sunday of upgrades and play, with safety checks along the way. You need two or three moving boxes, a craft knife or strong scissors, plain paper tape or flour paste, a pencil and an old towel.
Saturday Morning: Choosing and Preparing Boxes
Pick boxes that are clean, dry and free of strong smells. Double-walled moving boxes last longer than thin delivery boxes. Remove every bit of plastic tape, staples, labels and printed plastic wrapping, because kittens chew. Our guide to tape, ink and staples to avoid lists what to strip out. Leave the boxes open in a ventilated room for an hour if they smell of storage or damp.
Cats Protection's advice on bringing a cat home suggests giving a new kitten places to hide; a playhouse gives it one it can call its own from the first week.
Saturday: The One-Hour DIY Kitten Playhouse Build
- Mark two doorways about 12 cm wide on opposite sides of the first box, so the kitten is never trapped
- Cut the doorways with a craft knife, keeping fingers clear, and round the corners
- Cut a small window on a third side for peeking
- Fold the flaps in to strengthen the roof, or tape them flat with paper tape
- Join a second box to the first through matching doorways
- Line the floor with a folded towel
Keep all cutting on a board and away from the kitten. Put the knife away before the kitten comes near.
Kitten-Safe Materials and Joins
| Material | Use it | Avoid |
|---|---|---|
| Paper tape | For joins and edges | Plastic packing tape |
| Flour and water paste | For gluing panels | Hot glue strings |
| Plain cardboard | Walls and floors | Glossy printed boxes |
| Cotton towel | Floor lining | Loose-thread blankets |
If you use paste, let it dry fully before the kitten plays. Hot glue can leave thin strands that kittens chew; if you use it, trim every strand.
Saturday Afternoon: First Introductions
Put the playhouse on the floor in a quiet corner where the kitten already spends time. Drop a toy inside or a few kibbles at the entrance, then sit nearby and let the kitten explore in its own time. Do not push it inside. Most kittens are investigating within minutes; shy ones may wait until the room is quiet.
Sunday Morning: Adding a Tunnel
Cut both ends from a long, narrow box and tape it to one doorway to make a tunnel. Kittens love running through and ambushing toys at the far end. Keep the tunnel short enough that you can see through it, and make sure both ends are open so the kitten can always get out. Our cardboard castle rotation system shows how to swap tunnels for variety.
Sunday: Adding a Low Second Level
Put a smaller box on top of the main house and cut a hole in the roof below it, with a short ramp of folded cardboard inside for a young kitten. Keep the top level low; kittens are agile but clumsy, and a playhouse that tips over can scare them off it. Weigh the base with a heavy book inside a sealed bag under the towel if the house feels light.

Play Ideas for the Weekend
The Ohio State Indoor Pet Initiative's page on toys for indoor cats recommends toys that let cats chase and pounce. Use the playhouse doorways for peek-a-boo with a wand toy, roll a ball through the tunnel or hide treats under the towel for the kitten to find. Short sessions of a few minutes, several times a day, suit kittens best. Our 10-minute kitten play routine has a template.
Rules for Supervision
- Supervise play with any string or wand toy
- Check for loose pieces of tape or cardboard after each session
- Do not leave string toys inside the playhouse
- Remove the house if the kitten is chewing and swallowing cardboard
- Keep the craft knife and tape roll out of reach
Finding a Quiet Corner for the Box House
Choose a draft-free spot with a little natural light, away from heaters and fireplaces. A corner of the living room works well, so the kitten can play near the family but still retreat. International Cat Care's advice on making your home cat friendly recommends providing hiding places in quiet areas; a playhouse in a busy walkway will be used less.
Planning the Weekend Timetable
| When | Task | Time |
|---|---|---|
| Saturday morning | Strip boxes, air them out | 30 minutes |
| Saturday late morning | Cut and join the main house | Under 1 hour |
| Saturday afternoon | Introductions and short play | 10 minutes, several times |
| Sunday morning | Add the tunnel | 20 minutes |
| Sunday afternoon | Add the low second level and check stability | 30 minutes |
| Sunday evening | Final safety check and tidy up | 10 minutes |
The whole weekend adds up to about three hours of work, spread out so the kitten has time to get used to each new part before the next one arrives. If the kitten seems overwhelmed, leave the upgrades for the following weekend.
If Your Kitten Ignores the Playhouse
Some kittens take a few days to trust a new object. Rub a soft cloth on the kitten's cheeks and wipe it around the doorways, so the house smells familiar. Move it closer to where the kitten sleeps, or put its usual blanket inside instead of a new towel. Play with a wand toy near the entrance and let the lure disappear inside; curiosity usually wins. Avoid lifting the kitten into the house, which can make it wary. If the kitten still prefers a different box or the space under a chair, cut a doorway in that box instead and build from there. The best playhouse is the one the kitten chooses.
Daily and Weekly Checks
Each day, look for soggy, torn or chewed areas, and remove any loose bits. Shake out the towel. Each week, replace the towel with a clean one and decide whether a box needs replacing. Cardboard is meant to be temporary, so expect to swap out a panel every couple of weeks with an active kitten. If the kitten has an accident inside, replace that box.
Teaching Good Scratching Early
Kittens learn where to scratch early. Lay a small corrugated cardboard pad inside or next to the playhouse, and praise the kitten when it uses it. Our best corrugated cardboard for kitten scratchers and how to stop kitten scratching furniture guides explain what to try if the kitten starts on the sofa.
Making It a Family Project
Children can help decorate the outside with crayons or stickers on the outside walls only, away from doorways where the kitten might chew. Let them choose where the windows go. Keep the cutting to adults. Our kids and cats weekend cardboard castle build has more family-friendly ideas, and the cardboard castle and box enrichment hub collects other designs.
Moving Box Playhouse FAQs
Is cardboard safe for kittens?
Plain, clean cardboard is generally safe for supervised play. Remove all plastic tape, staples, labels and glossy printing first. Replace boxes that become soggy, torn or heavily chewed, and stop using them if your kitten is swallowing pieces of cardboard.
How big should the doorways be in a kitten playhouse?
Doorways about 12 cm wide suit most kittens. Cut at least two, on different sides, so the kitten can never be cornered inside. As the kitten grows, enlarge the doorways or build a new house from bigger boxes, and round off every cut corner so whiskers and paws do not catch.
What can I use instead of tape to join boxes?
Plain paper tape or a paste made from flour and water works well and is safer than plastic packing tape. Let paste dry fully before play. If you use hot glue, trim every thin strand so the kitten cannot chew them.
How long does a cardboard playhouse last?
With an active kitten, expect to replace a panel every couple of weeks and the whole house after a month or two. Check it daily for chewed or soggy areas and remove loose bits. Replace any box the kitten has had an accident in.
