Understand what cats like before you start building

To design a cat tree your pet will actually use, it helps to understand feline behavior.

Here’s what cats naturally gravitate toward:

Vertical space: Cats love to climb and observe from above
Scratching surfaces: Essential for claw maintenance and marking territory
Perches: Flat, comfy spots to nap or survey their domain
Hiding spots: Enclosed cubbies or hammocks provide security
Toys and movement: Hanging toys or dangling ropes add entertainment

Materials you’ll need to build a sturdy DIY cat tree

To make a sturdy and safe DIY cat tree, you’ll want quality materials. Here’s a list to get you started:

Plywood or MDF board (for platforms and base)
2x4s or other wood posts (for vertical supports)
Sisal rope (ideal scratching surface)
Carpet remnants or fleece (for comfort and grip)
Wood screws, bolts, and brackets
Staple gun staples and wood glue
Non-toxic paint or sealant (if finishing the wood)

Pet-safe tip: Always choose untreated wood and non-toxic adhesives or finishes.

Budget-friendly options: Repurpose old furniture, cardboard tubes, or scraps from a hardware store.

Expert-backed tips for choosing the right materials

Use safe, natural materials to build lasting trees
“Stick to untreated wood like pine or plywood and natural sisal rope,” advises Dogs District. “These materials are both durable and pet-safe. Avoid any toxic finishes or splinter-prone surfaces for your cat’s safety.”

Repurpose natural materials for a rustic, safe design
“Repurposed tree stumps or branches can make beautiful, stable cat trees,” says Katzenworld. “Secure them to a heavy base like a paving stone using proper drilling tools. These natural elements add character to your home and give your cat a taste of the outdoors.”

Solid wood and sisal rope create long-lasting durability
“We design our trees using real wood and natural sisal for superior durability,” explains At Hilde & Phil. “Cats can be tough on furniture, so secure all vertical posts to a weighted base. These core principles have helped us build pieces that thousands of cats still love today.”

Support vertical movement with thoughtful traction and design
“Cats experience their world vertically, so a good cat tree should support that safely,” says Cat Therapy. “Wider bases, textured surfaces like cork, and performance velvet cushions can make a huge difference. Mixing materials also helps your design blend with your home while enriching your cat’s environment.”

Pick materials cats love
“Choose fleece for soft bedding and sisal for scratching,” advises Severn Wishes. “Hoover your tree weekly to remove fur and check for loose parts. Multilayer structures give cats places to hide, climb, and lounge.”

How to build your own cat tree in 7 steps

You can adapt these steps based on your chosen style, but this general process works for most DIY cat trees.

1. Plan and measure

Sketch your design first
Measure your space and decide how tall/wide the tree will be
Plan where each level and feature will go

2. Cut the wood

Use a circular saw to cut platforms, base pieces, and vertical supports
Sand edges to prevent splinters

3. Assemble the base and supports

Attach vertical posts to a large, heavy base for stability
Use wood screws and brackets for secure fastening
Double up the base if needed for extra support

4. Add platforms and perches

Stagger them to encourage climbing
Use screws or corner brackets to attach each level

5. Wrap posts with sisal rope

Apply glue in sections and tightly wrap rope around posts
Staple rope ends down for extra hold

6. Cover surfaces with carpet or fabric

Cut carpet or fleece to size and staple or glue it down
Cover perches and cubbies for comfort

7. Safety checks and stability

Test each section to ensure it holds your cat’s weight
Make sure the structure doesn’t wobble or tip
Anchor the tree to a wall for extra safety (especially if tall)

Expert tips for building a stable, functional cat tree

Stability is the foundation of a safe cat tree
“When designing a DIY cat tree, always prioritize stability,” advises Sophisticated Scratch. “Use a wide, sturdy base—especially for large or active cats—and avoid hazardous fasteners like exposed staples or nails. Thick lumber and non-toxic materials go a long way in creating a safe space your cat can trust.”

Maximize vertical space while protecting stability
“To fully engage your cat’s climbing instincts, consider building a floor-to-ceiling cat tree—but don’t exceed 126 inches,” says Petomg. “Beyond that height, even tight ceiling fits can lead to instability over time. We recommend rubberwood for a durable, premium feel, and adding toys or catnip at the top to encourage exploration.”

Design vertically with both function and style in mind
“Cats love to climb and perch, so always think vertically when building a DIY cat tree,” says Clean Litter Club. “Use real wood and sisal rope for strength and scratchability, and don’t shy away from incorporating style. Just like with DIY litter box furniture, your design can be both functional and look great in your home.”

Mind the spacing and positioning for better usability
“When building a cat tree, use a heavy 24-inch base and space platforms 12 to 18 inches apart,” recommends Step4Ward Media. “This setup makes jumping and climbing easier for cats of all ages. Place the tree by a window to add visual stimulation and natural light.”

Build with safety, not just height, in mind
“Real wood and wide bases are non-negotiables for stability,” says Tabbycatcorner. “I use glue and screws for every platform, and always anchor taller builds to prevent tipping. Rope posts last longer than carpet, and platforms at varied heights keep my cats engaged.”

Start with structure, then add comfort and enrichment
“A wide base, strong brackets, and sturdy materials like PVC or wood make all the difference,” says PetsWeekly. “Sisal rope satisfies scratching needs, while soft fabrics create inviting nap spots. Always test for wobble—especially with active cats—and anchor if needed.”

Change the layout to keep cats curious
“Use different-sized trees, modular shelves, or movable setups to create variety,” recommends Chicago Black Cat. “Positioning trees near window ledges or furniture gives cats fresh perspectives. Rotating the layout occasionally helps prevent boredom.”

Design for all ages and abilities
“Consider age, size, and temperament when designing your cat tree,” shares Cats with Jazz. “Stability is key, but so is accessibility. Ramps, cozy hideaways, and perch levels offer enrichment for kittens, seniors, and every cat in between.”

Optional upgrades to enhance your DIY cat tree

Want to go above and beyond? Here are a few fun upgrades:

Hammocks: Hang a fabric sling between posts
Ramps or bridges: Connect levels or extend to other furniture
Cubby holes: Add enclosed boxes for cozy naps
Wall-mounted extensions: Let the cat tree connect to shelves
Integrated toys: Dangle feathers, balls, or bells from posts

Expand cat territory with stylish DIY shelf hacks
“You don’t have to sacrifice style for your cat’s happiness,” explains Hauspanther. “Try repurposing shelves by adding non-slip surfaces like yoga mats or rug remnants. This simple, low-cost approach gives your cat more space to explore—without cluttering your decor.”

Mix textures and design for your cat’s senses
“When you build a cat tree, think like a cat designer,” says Shichic. “Combine sisal, wood, and faux fur for tactile variety. A touch of catnip and smart placement make it both inviting and functional—without sacrificing your style.”

Design your cat tree like functional home décor
“Treat your DIY cat tree like a sculpture that both you and your cat will love,” says Catenary Home. “Use solid wood for structure, add soft cushions, and create at least three tiers in a natural flow. Neutral tones and high-end materials can help it become a lasting centerpiece in your home.”

Where to place your DIY cat tree for maximum cat happiness

Choosing the right location is just as important as the tree’s design. Cats love being part of the action—but they also crave security. Here’s what to consider:

Place it near a window: Most cats love to sunbathe and watch the world go by.
Avoid isolated corners: Choose spots where your cat already hangs out or where you spend time, like the living room or home office.
Use wall support for tall trees: If your tree is over 4 feet, placing it against a wall adds stability and gives your cat a sense of safety.
Mind traffic flow: Make sure your cat has easy access without being in the way of foot traffic or noisy appliances.
Create a cat-friendly zone: If you have multiple cats, place additional trees in different areas to reduce territorial tension.

Choose the best location to enrich your cat’s day
“Cats love being near their people and soaking up the sun,” says CatScapes. “Position your cat tree near a window or in a room you frequent. If your cat prefers privacy, try placing it between walls or in a corner for a cozy, secure feel.”

Safety tips for building a secure DIY cat tree

Keeping your cat safe is priority #1. Keep these tips in mind:

Stability matters: Use a wide base and heavy materials
Anchor if needed: Secure the tree to the wall with L-brackets
Avoid sharp edges: Sand all corners and surfaces
Use pet-safe materials: No treated wood, toxic glue, or flaking paint
Maintain regularly: Tighten screws, replace worn-out parts, and clean surfaces

Use sisal rope for safety and multi-cat harmony
“We recommend using a wide 24-inch base and sisal rope instead of carpet,” says Cat Aquariums. “It’s safer for claws, easier to replace, and provides better grip. For multi-cat homes, build multiple platforms and ensure each cat has a private hideaway.”
