13 Cozy Cat Bed Ideas Using Simple Cardboard
Let’s be honest—if you bring home a fancy, expensive cat bed, your cat will probably ignore it and sleep in the Amazon box it came in. We’ve all been there. Instead of fighting it, why not lean into your cat’s love for cardboard? It’s free, endlessly customizable, and surprisingly cozy when you add the right touches.
I’ve spent way too many weekends turning old shipping boxes into little palaces for my own furball. Here are 13 of my favorite DIY cardboard cat bed ideas that are simple, budget-friendly, and actually look cute in your home. Grab a box cutter and some tape—let’s get crafting!
1. The Classic Donut Bed
This is the easiest win. Take a large, shallow box and cut the sides down to about four inches high. Then, roll up an old towel or sweater into a circle and place it inside the box to form a rim. That’s it. Your cat gets that secure, cradled feeling without any complicated cutting.
The key here is making sure the box is wide enough for your cat to stretch out. If the rim is too high, they’ll feel trapped. Keep it low and plush.
I like to add a fleece blanket at the bottom so it feels extra soft against their paws. It’s the kind of bed they’ll sink into and refuse to leave.

2. The Hidden Cave Box
Some cats love to be completely covered. For this one, use a taller box, like a medium-sized moving box. Cut a round doorway on one side, about six inches from the bottom. Make sure the edges are smooth—sand them down or cover them with duct tape so your cat doesn’t get scratched.
Place a soft cushion or an old pillow inside. The darkness makes it perfect for shy cats or kittens who need a safe space to nap.
One tip: don’t make the doorway too big. Cats prefer a snug entrance they have to squeeze through a little. It makes them feel hidden and secure.

3. The Flat Tray Lounger
If your cat is a sprawler, they don’t want walls. They just want a flat, stable surface. Take a sturdy box and cut it down so the sides are only two inches high. This creates a low tray that’s perfect for belly-up naps.
The low edges give them a sense of boundary without confining them. It’s also great for hot days when they want to press their belly against something cool.
You can line it with a thin cotton cloth or leave it bare. Some cats actually love the texture of plain cardboard against their fur.

4. The Double-Decker Box
Have two boxes of different sizes? Stack them. Tape the smaller one securely on top of the larger one. Cut a hole in the top of the bottom box and the bottom of the top box so they connect. This gives your cat two levels to choose from.
Put a soft bed in the bottom box and leave the top box empty with a towel. Cats love having options, especially when they can look down on the world from above.
Make sure the structure is stable before you let your cat try it. You don’t want it wobbling and scaring them off.

5. The Scallop Edge Box
This one looks fancy but is actually super simple. Take a medium box and cut the sides down to about six inches. Then, cut scalloped curves along the top edge—like a pie crust. It looks adorable and fits perfectly into a boho or farmhouse decor vibe.
Use a pencil to sketch the curves before you cut. This makes it look intentional rather than messy.
Add a chunky knit blanket inside. The scalloped edges give your cat a nice spot to rest their chin while they watch you work.

6. The Multi-Box Cat Lounge
Why settle for one box when you can make a whole complex? Tape three or four boxes together in a row. Cut connecting holes between them so your cat can travel from one to the other without leaving the cardboard kingdom.
Put different textures in each box—one with a towel, one with a fleece blanket, one with a crinkly paper bag. This keeps things interesting for curious cats.
It’s a great project for a rainy afternoon. Just make sure the boxes are all roughly the same height so the floors line up.

7. The Hanging Hammock Box
This one takes a little more effort but is worth it. Cut a large box into a rectangular shape, leaving the bottom intact. Then, using strong rope or straps, hang it from a sturdy table or a wall-mounted hook. The box becomes a swinging bed.
Make sure you reinforce the corners with extra tape and duct tape. The last thing you want is your cat crashing down mid-nap.
Place a soft blanket inside. The gentle rocking motion will put them right to sleep, just like a baby.

8. The Window Sill Box
If your cat loves watching birds, this is the bed for them. Find a flat, shallow box that fits snugly on your windowsill. Cut the sides down to about three inches. Then, place a folded towel inside.
The shallow sides let them see out easily while still giving them a defined space. It’s like their own personal observation deck.
You can add a small piece of non-slip shelf liner underneath the box so it doesn’t slide around when they jump in and out.

9. The Corner Wedge Bed
Got a corner that’s not being used? Make a bed that fits right into it. Find a box that’s roughly square, then cut it diagonally from one corner to the opposite to create a triangular shape. Or simply cut the box in half diagonally.
This fits neatly into a corner and gives your cat a cozy, enclosed feeling without taking up too much floor space.
Line it with a soft throw pillow or an old sweatshirt. The triangle shape feels safe and snug.

10. The Cardboard Crate with a Curtain
This is for the dramatic cats. Take a tall box and cut a large opening on one side. Then, instead of leaving it open, tape a piece of fabric over the opening, leaving a slit in the middle. Your cat has to push through the fabric to get in.
This creates a sense of privacy that cats absolutely love. It’s like their own little fort.
Use a lightweight fabric like cotton or linen so it’s easy for them to push through. The heavier the fabric, the more frustrating it is.

11. The Two-Box Tunnel
Cut the bottom out of two boxes. Then, tape them together end to end, creating a long tunnel. Add a soft blanket at one end. Your cat can run through the tunnel and crash into the cozy pile at the end.
This is perfect for kittens or active cats who like to play before they nap. The tunnel gives them a fun path to zoom through.
Make sure the tunnel is wide enough for your cat to turn around in. If it’s too narrow, they’ll feel trapped.

12. The Elevated Box Bed
Use two sturdy boxes. Tape them together so one is on top of the other. Cut a hole in the top box so your cat can climb inside. The bottom box stays solid as a base. This gives you a raised bed that keeps your cat off the cold floor.
It’s perfect for older cats who have joint pain and need some extra warmth. The elevation helps keep them cozy.
Place a thick folded blanket in the top box. You can even add a heating pad underneath it (on low) for extra comfort on chilly days.

13. The Simple Flat Cardboard Pad
Sometimes the best bed is no bed at all. Cut a piece of cardboard to the size of a standard cat bed. Then, simply fold a soft blanket over it and place it on the floor. The cardboard gives it a little structure and keeps the blanket from sliding around.
It’s the most minimal option on this list, but it works. Cats love the combination of soft blanket and firm cardboard underneath.
If your cat is picky, this is the one to try first. It’s so simple that there’s nothing to reject.

Final Thoughts
Cardboard is honestly the best cat toy and bed material out there. It’s free, recyclable, and you can replace it whenever it gets worn out. Your cat doesn’t care if it’s ugly—they just care that it smells like home and feels safe.
I’ve made at least five of these and my cat has a favorite for every mood. Try a couple of these and see which one your furry friend likes best. You might be surprised by what they choose.
FAQ
Is cardboard safe for cats to sleep on?
Yes, plain cardboard is safe. Just make sure there are no staples, tape, or sharp edges. Smooth down any rough cuts with sandpaper or cover them with duct tape.
How long does a cardboard cat bed last?
It depends on your cat’s scratching habits. Some beds last months, others only a few weeks. When it gets flimsy or dirty, just recycle it and make a new one.
What if my cat doesn’t like the box?
Try placing a piece of your worn clothing inside, like an old t-shirt. Your scent will make it more appealing. Also, try putting it in a quiet corner where they already like to nap.
Can I paint or decorate the cardboard?
Absolutely. Use non-toxic acrylic paint or washi tape to make it look cute. Just make sure the paint is fully dry before your cat uses it.
How do I clean a cardboard cat bed?
You can’t really wash cardboard. Instead, use a removable blanket or towel inside. When the cardboard gets dirty or smells, it’s time to toss it and build a fresh one.
