How To Build A DIY Cat Tree Using Repurposed Furniture And Sisal Rope

Cats thrive in vertical spaces. They instinctively seek high perches for safety, observation, and exercise. Commercial cat trees can be expensive, bulky, and often made with low-quality materials that don’t last. A smarter, more sustainable solution is building your own cat tree using repurposed furniture and sisal rope. This approach not only reduces waste but also allows you to tailor the design to your home’s layout and your cat’s unique behaviors. With basic tools, some creativity, and a few hours of work, you can construct a durable, stylish, and functional climbing structure that blends seamlessly into your living space.

Why Build a Cat Tree from Repurposed Materials?

Traditional cat trees are often constructed from particleboard, synthetic fabrics, and glued joints that degrade quickly under scratching and daily use. By contrast, repurposing old furniture—such as end tables, dressers, or wooden shelves—provides a sturdier foundation. Solid wood frames from secondhand nightstands or bookshelves offer load-bearing strength that supports even large cats during vigorous play.

Sisal rope, known for its coarse texture and durability, is ideal for scratching posts. Unlike carpet or fabric, it resists fraying and mimics the rough bark cats naturally scratch in the wild. Combining these elements creates a cat tree that satisfies instinctual behaviors while reducing environmental impact.

“Cats benefit emotionally and physically from having dedicated vertical territory. A well-built, stable cat tree encourages healthy scratching and reduces stress-related behaviors.” — Dr. Lena Ruiz, Feline Behavior Specialist

Tip: Look for furniture with flat surfaces and square edges—these are easier to modify and safer for cats to balance on.

Materials and Tools You’ll Need

Before starting construction, gather all necessary supplies. Using reclaimed materials means inventorying what you already have or sourcing affordable items from thrift stores, online marketplaces, or curbside pickups.

Core Components

• Repurposed furniture base: Sturdy side table, small dresser, or wooden stool
• Sisal rope: 3/8-inch thickness, natural fiber (minimum 50 feet depending on size)
• Wooden poles: Untreated pine or hardwood dowels (2–4 inches in diameter)
• Platforms: Scrap plywood, old shelves, or drawer fronts
• Fabric remnants: Fleece or carpet scraps for bedding areas
• Non-toxic wood glue: For securing layers and joints
• Heavy-duty screws: At least 2 inches long for structural integrity
• Staple gun and staples: To attach fabric and sisal

Essential Tools

• Power drill with screwdriver bits
• Hand saw or circular saw (for cutting wood)
• Measuring tape and level
• Scissors or utility knife
• Sandpaper (medium and fine grit)

Tip: Always sand down sharp edges and splinter-prone surfaces before letting your cat interact with the structure.

Step-by-Step Construction Guide

Follow this detailed sequence to assemble a safe, engaging cat tree using repurposed components.

1. Evaluate and prepare the base furniture. Choose a piece at least 18 inches tall with a flat top. Remove drawers, hardware, or loose parts. Sand any rough areas and ensure the unit doesn’t wobble. If needed, reinforce legs with corner brackets.
2. Attach vertical support poles. Determine where you want scratching posts. Drill pilot holes into the base and secure wooden dowels vertically using wood glue and screws driven through the bottom or sides. For added stability, anchor the pole internally if the base has cavities (e.g., inside a hollow nightstand).
3. Wrap poles with sisal rope. Starting at the base, apply a dab of wood glue and begin wrapping the rope tightly around the pole. Overlap each layer slightly to prevent gaps. Secure every 6–8 inches with staples driven into the wood. Continue until the pole is fully covered, then glue and staple the end. Allow 24 hours for adhesive to cure.
4. Build elevated platforms. Cut scrap wood into rectangular or circular platforms (12x12 inches minimum). Sand edges smooth. Attach to the main structure using L-brackets and screws. Position them near the top of sisal-wrapped poles so cats can climb up and rest. Angle platforms slightly inward for better grip.
5. Add resting spots and hideaways. Repurpose shallow drawers or open boxes by lining them with soft fabric. Secure them to platforms using brackets or adhesive. Alternatively, mount a cushioned hammock between two poles using heavy-duty straps.
6. Incorporate interactive elements. Hang dangling toys from platform undersides using braided cotton cord. Avoid small parts that could be chewed off. Rotate toys weekly to maintain interest.
7. Final inspection. Shake the structure firmly to test stability. Confirm all screws are tight, ropes are secure, and no sharp points remain exposed. Wipe down with a damp cloth to remove dust.

Timeline for Assembly

Stage	Estimated Time	Notes
Planning & Sourcing	1–3 days	Search local listings; inspect for wood quality
Preparation	1–2 hours	Sanding, disassembly, measuring
Construction	3–5 hours	Allow drying time between glue steps
Finishing & Testing	1 hour	Add fabric, inspect stability
Total Active Time	5–8 hours	Over 2–3 sessions recommended

Design Considerations for Multi-Cat Households

If you have more than one cat, design becomes critical. Conflicts often arise when resources like perches or hiding spots are limited. A well-planned cat tree should allow multiple cats to occupy different levels without feeling crowded.

Include at least one escape route or secondary exit point, especially if placing the tree near walls. Cats prefer being able to observe their surroundings, so position the tree near a window or in an open area of the room. Avoid overcrowding with too many platforms—prioritize quality over quantity.

Do’s and Don’ts for Safe Design

Do	Don't
Use untreated, non-toxic wood	Paint or stain surfaces cats may lick
Anchor tall structures to the wall	Allow wobbling or tipping hazards
Provide multiple entry/exit points	Create enclosed spaces with only one exit
Test weight capacity with gradual use	Assume all old furniture is structurally sound

Tip: Place a soft rug beneath the cat tree to cushion falls and protect flooring from scratches.

Real Example: Transforming an Old Nightstand into a Cat Tower

Sarah, a pet owner in Portland, Oregon, rescued a damaged wooden nightstand from a curb during bulk trash pickup. The piece had a chipped veneer and a missing drawer knob, but the frame was solid maple. Instead of discarding it, she decided to convert it into a space-saving cat tree for her two indoor cats, Milo and Luna.

She removed the remaining drawer and reinforced the internal shelf with cross-bracing. She drilled holes in the top corners and inserted two 3-inch-diameter wooden poles, securing them with epoxy and screws. After wrapping both poles in natural sisal rope, she attached a 14x14-inch plywood platform to the top using metal brackets. On one side, she mounted a repurposed drawer lined with fleece as a cozy sleeping nook.

The final product stood 48 inches tall, fit perfectly beside her couch, and gave both cats access to elevated lounging and scratching. “They use it every day,” Sarah said. “Milo spends hours sharpening his claws, and Luna naps on top like it’s her throne.”

Expert Tips for Long-Term Use and Maintenance

A well-built cat tree can last years with minimal upkeep. However, regular inspection ensures continued safety and functionality.

• Check sisal wraps monthly for loosening or excessive wear. Re-staple or re-wrap sections as needed.
• Vacuum platforms and fabric surfaces weekly to remove fur and dander.
• Tighten screws and brackets every 3–6 months, especially in homes with active cats.
• Rotate or replace dangling toys to prevent boredom and chewing hazards.
• If the base begins to wobble, install anti-tip brackets anchored into wall studs.

“Durability starts with smart material choices. Sisal and solid wood outperform synthetic alternatives in both function and longevity.” — Mark Tran, Pet Furniture Designer

Frequently Asked Questions

Can I use carpet instead of sisal rope?

You can, but sisal is far superior for scratching. Most carpets are too soft and wear out quickly. If you must use carpet, choose commercial-grade loop-free varieties and attach them securely with staples and adhesive.

How do I get my cat to use the new tree?

Place treats, catnip, or a favorite toy on upper platforms. Spend time nearby encouraging exploration. Some cats take days to warm up to new structures—patience is key. Avoid forcing interaction.

Is it safe to anchor a cat tree to drywall?

No. Drywall anchors may fail under stress. Always secure wall brackets into wooden studs using appropriate fasteners. Use a stud finder to locate framing before installation.
