21 DIY Cat House Ideas: Keep Your Furry Friend Cozy and Happy
Let’s be honest—cats are basically little rulers of our homes. They demand comfort, style, and sometimes an irrational amount of attention.
But giving them their own space doesn’t have to mean spending a fortune on fancy store-bought houses.
I’ve tried a few DIY solutions myself, and let me tell you, there’s nothing more satisfying than seeing your cat immediately claim your creation as their throne.
So, whether you’re working with cardboard, wood, or just a pile of blankets, here are 21 creative DIY cat house ideas that will keep your furball cozy and you smiling.
1. Cardboard Castle
Yes, it sounds basic, but hear me out. Cardboard is cheap, easy to cut, and surprisingly durable if you layer it right.
- Use multiple boxes to create a multi-level castle.
- Cut windows and doors for peek-a-boo fun.
- Add blankets inside for a soft touch.
My cat literally spends hours pretending to be royalty in hers.
2. Upcycled Wooden Crate House
Old wooden crates can become stylish cat houses with minimal effort. Stack them, paint them, or just leave them rustic.
Pro tip: Sand any rough edges and line with a cushion. Your cat will appreciate the comfy interior without splinters.
3. Hanging Hammock Bed
Cats love to feel elevated and safe. A hammock that hangs between two supports or under a shelf is perfect.
- Use sturdy fabric.
- Secure it well with hooks.
- Optional: add a pillow for extra comfort.
My cat refuses to touch the floor now—she’s too busy lounging like a tiny, judgmental queen.
4. PVC Tube Playhouse
PVC pipes are surprisingly versatile. Connect them to create tunnels and cubbies that cats can crawl through and nap in.
Why it works: Cats love hiding spots, and the tubes double as a playful maze.
5. Cardboard Igloo
Round shapes are cozy. Take a large box, cut a circular entrance, and add a soft blanket inside.
Extra touch: Paint the outside or wrap it with fabric for style. My cat calls it “her secret bunker.”
6. Suitcase Cat House
Old suitcases aren’t just vintage décor—they’re cozy hideaways. Remove one side, add a cushion, and suddenly your old suitcase is a cat palace.
FYI: My cat took over mine within minutes, ignoring all other beds I bought her.
7. Blanket Fort House
You know those blanket forts you made as a kid? Cats love them too.
- Use a small table or box as a frame.
- Drape a blanket over it.
- Add pillows inside.
Easy, fast, and your cat will feel like the ruler of a secret kingdom.
8. Wooden Shelf Perch
Install a small shelf in a quiet corner. Line it with a soft cushion. Cats love height, and it keeps them off the floor.
- Bonus: doubles as a lookout point.
- Easy to clean underneath.
My cat sits there all day, silently judging everyone. Classic cat behavior.
9. Cardboard Condo with Multiple Levels
Stack smaller boxes to create a multi-story condo. Cut doors between levels for exploration.
Why it works: Cats love climbing and jumping, so this keeps them active.
10. DIY Cat Teepee
Teepees aren’t just for kids. A small wooden frame with fabric draped over it creates a snug little den.
- Add a pillow or blanket inside.
- Optional: attach a hanging toy for entertainment.
This one’s a hit with shy cats—they can retreat and feel safe.
11. Mason Jar Cat House Accent
Okay, hear me out—tiny mason jars can’t house your cat, but using them for accessories or a mini “entrance area” adds charm to any DIY house.
- Attach jars as food or water stations.
- Keeps small accessories organized.
It’s a subtle touch that makes your project feel professional.
12. Pallet Cat House
Wood pallets are cheap and plentiful. Sand them down, stack creatively, and add cushions to make a rustic cat home.
- Multi-level stacking encourages climbing.
- Easy to customize.
My cat loves the gaps between the pallets—it doubles as a hide-and-pounce zone.
13. Hanging Basket Hideaway
Baskets are perfect for DIY wall-mounted houses. Hang them securely and add a cushion.
Tip: Make sure your basket is strong enough—safety first!
14. Repurposed Drawer Cat Bed
Old drawers from dressers? Perfect for a cozy, stylish cat bed.
- Remove one side for easy entry.
- Sand rough edges.
- Add a soft blanket inside.
It’s like giving your cat a mini apartment.
15. Fabric Cube House
Sew or buy fabric cubes that fit together to make modular cat houses.
- Stack or arrange in different configurations.
- Cats love climbing inside and between cubes.
I made one, and my cat spends hours popping in and out like a little ninja.
16. Cardboard Tunnel Maze
Combine several cardboard tubes or boxes to make a maze-like tunnel system.
- Add small entrances and exits.
- Encourage exploration with treats.
Cats love to stalk through tunnels—it’s basically their indoor jungle.
17. DIY Cat Igloo with Foam
Use craft foam or soft insulation boards to make a semi-rigid igloo shape. Cover with a blanket or faux fur.
Why it works: Keeps warmth in and creates a super cozy nook.
18. Wall-Mounted Cat Steps
Not exactly a house, but steps leading to high shelves or perches make a functional DIY home.
- Allows cats to climb safely.
- Keeps them entertained.
Perfect for small apartments where floor space is limited.

It’s simple but surprisingly effective.

Milk crates aren’t just for storage. Stack them, cut openings, and create a multi-level adventure house.

Final Thoughts
Building a DIY cat house doesn’t have to be complicated, expensive, or Pinterest-perfect. The best projects combine comfort, safety, and a touch of creativity.
