How to Make a Cat House Out of Wood Pallets: DIY Guide

Building a cat house from wood pallets is a rewarding project for any pet owner. With a bit of planning and simple tools, you can create a cozy, durable shelter for your cat—whether it’s an indoor haven or an outdoor retreat.

Wood pallets are cheap, often free, and surprisingly versatile. Many people overlook pallets, but they can be transformed into something beautiful and practical. Here, you’ll learn everything you need to make your own cat house from wood pallets, with clear steps, tips, and guidance for beginners.

Why Use Wood Pallets For A Cat House?

Wood pallets are popular for DIY projects because they are affordable, strong, and recyclable. Most pallets are made from hardwoods like oak or pine, which provide stability and a rustic look. According to the EPA, over 500 million pallets are produced in the US each year, and many end up as waste. Repurposing them helps reduce landfill and saves money.

Pallet wood is ideal for a cat house because:

• It handles weather well (with proper treatment)
• It’s easy to work with basic tools
• You can find them free at warehouses, stores, and shipping centers

But not all pallets are safe. Always check for markings like “HT” (heat treated), which means the wood is safe for pets. Avoid pallets with “MB” (methyl bromide), as this chemical is toxic.

Planning Your Cat House

Before you start, think about your cat’s needs and your space. Ask yourself:

• Will the house be indoors or outdoors?
• How big should it be for your cat?
• Do you want one or more levels?
• Will you add features like scratching posts or windows?

Outdoor cat houses need weather protection, while indoor houses can be simpler. Most cats prefer a space that is at least 18 x 18 inches and 12 inches tall. If you have more than one cat, adjust the size for comfort.

Sizing Guide

Here’s a quick sizing reference for different cat types:

Gathering Materials And Tools

You don’t need fancy equipment. The basics are enough for most pallet projects. Here’s what you’ll need:

• 2–3 wood pallets (heat-treated only)
• Hammer or pry bar
• Saw (hand saw or circular saw)
• Sandpaper or power sander
• Screws or nails (1.5 to 2 inches)
• Drill
• Measuring tape
• Pencil
• Wood sealer or pet-safe paint
• Hinges (optional, for doors or roofs)
• Waterproof roof material (for outdoors)

Optional extras:

• Insulation (foam or old blankets)
• Cat bedding
• Clear plastic for windows

Preparing Your Pallets

Most pallets are rough and may contain nails or dirt. Preparing them well is vital for your cat’s safety.

• Inspect each pallet: Remove broken pieces, nails, or staples.
• Wash thoroughly: Use soap and water, let dry fully.
• Disassemble: Pry apart the boards gently to avoid splitting.
• Sand all surfaces: Smooth any rough edges and splinters.

A common mistake is skipping the sanding step. Cats’ paws are sensitive, and rough wood can cause injury. Be patient—this step makes a big difference.

Designing The Cat House Structure

You can build a simple box or get creative with multiple levels. For beginners, a single-level house is easiest. Here’s a basic plan:

• Four walls (pallet boards)
• Floor (pallet boards)
• Roof (pallet boards or waterproof material)
• Entry hole (about 6–8 inches wide)
• Optional: Window or ventilation hole

Start with the basic box if you’re new to woodworking. You can always add extra features later.

Step-by-step Construction Guide

Let’s walk through building a single-level cat house.

1. Cut Your Pallet Boards

Measure and cut boards for the walls, floor, and roof. For a medium cat house:

• Walls: Four boards, each 18 inches long
• Floor: Four boards, 18 inches long
• Roof: Four boards, 18 inches long

Double-check measurements before cutting. Mistakes here waste wood and time.

2. Assemble The Floor

Lay four boards side by side. Screw or nail them into two crosspieces underneath for stability. This creates a strong base.

3. Build The Walls

Attach the wall boards vertically to the floor. Secure each board with screws or nails. Assemble three sides first, leaving one side open for the entry hole.

4. Create The Entry Hole

Cut a hole about 6–8 inches wide and 8–10 inches tall in one wall. Smooth the edges with sandpaper.

5. Attach The Roof

Place roof boards across the top. For outdoor houses, cover the roof with waterproof material like plastic sheeting or shingles.

6. Add Extras

Install a window for light or ventilation, using clear plastic. Add insulation if needed—especially for outdoor houses.

7. Paint Or Seal

Apply pet-safe wood sealer or paint. This protects the wood and helps it last longer. Avoid strong-smelling products—cats dislike harsh odors.

Practical Tips For A Safe, Cozy Cat House

• Elevate the house: Raise it 2–4 inches off the ground to prevent dampness and insect problems.
• Add bedding: Use washable blankets or soft foam.
• Ventilate: A small window or hole helps airflow and keeps the house from smelling musty.
• Secure the roof: Use hinges for easy cleaning access.
• Check stability: Make sure the house doesn’t wobble or tip.

Many beginners forget to add elevation or ventilation. These features are simple but make a big difference for your cat’s comfort and health.

Decorating And Personalizing

Cats love cozy spaces, so add personal touches:

• Paint the house with your cat’s name
• Attach scratching posts or pads to the sides
• Add toys inside
• Use colorful, pet-safe fabrics

Don’t use stickers or decorations your cat might chew. Instead, focus on items that are fun and safe.

Maintaining Your Cat House

Regular maintenance keeps your cat house clean and safe:

• Inspect for loose nails or boards every month
• Wash bedding weekly
• Check for mold, especially after rain
• Reapply wood sealer once a year

If you use your house outdoors, place it in a sheltered spot, such as under a porch or against a wall. This protects it from harsh weather.

Maintenance Comparison

Here’s a quick look at upkeep for indoor vs. outdoor cat houses:

Common Mistakes And How To Avoid Them

• Using untreated or toxic pallets: Always check markings. Only use heat-treated wood.
• Skipping sanding: Rough wood can injure your cat.
• Ignoring ventilation: Cats need fresh air. Add a window or hole.
• Making entry hole too small: Measure carefully. Cats need space to enter comfortably.
• Not securing the structure: Loose boards or nails can cause accidents.

Many beginners think a “quick build” is good enough. But quality matters more than speed. Take time to do each step well.

Real-life Examples

People around the world have built amazing cat houses from pallets. For example, a shelter in Oregon built 20 pallet cat houses for feral cats in winter. They insulated each house with foam and raised them off the ground. The cats stayed warmer and healthier, and the project cost less than $30 per house.

Another pet owner in Texas created a two-story pallet cat house with ramps, windows, and scratching posts. Their cats loved climbing and exploring different levels.
