DIY Cat Tree

How to Build a Custom Cat Tree at Home

Creating a DIY cat tree is a fun and rewarding project that provides your feline friend with a space to climb, scratch, and lounge. Instead of spending hundreds of dollars on store-bought cat furniture, you can build a custom cat tree suited to your home’s space and your cat’s needs. With just a few tools, materials, and creativity, you can construct a durable, stylish, and budget-friendly cat tower. This guide walks you through everything—from planning and materials to the step-by-step building process.

Introduction

Last spring, we took in an abandoned kitten. Our fat old cat was accepting enough, giving a little nuzzle, but the dogs were another story. They were apoplectic at this new addition, so we needed a cat tree—fast. (For the record, the dogs and cat have since become friends.)

Cat trees, towers, and window perches allow cats to survey their territory from above, giving them a sense of security and a place to relax far from the chaos below. The standard pet-store cat tree worked for a while, but my dream of a custom cat tree—complete with ramps, hammocks, and hideaways—wasn’t going to come from a boxed purchase. I needed something that fit my space and my cat’s adventurous spirit.

This guide details the process of building a DIY cat tree from scratch. It took about two days to complete, and it’s a big structure, perfect for an open floor plan with high ceilings. However, you can scale it down by making a smaller base and reducing the number of levels if needed.

Why Build Your Own Cat Tree?

• Customizable: Adjust size, style, and materials to match your space.
• Budget-Friendly: Use reclaimed wood and affordable materials.
• Durable: Sturdy construction lasts longer than store-bought options.
• Engaging for Cats: Add hammocks, ramps, and scratching posts.

Now, let’s dive into the materials and tools required for this DIY cat tree project.

Tools Required

Before you start, gather the following tools to make construction smoother and more efficient:

• Circular saw – For cutting wood to size
• Drill or impact driver – To secure screws and assemble components
• Drill bits (various sizes) – For drilling pilot holes
• Hammer – To drive in nails where needed
• Hot melt glue gun – For attaching carpet or fabric
• Jigsaw (optional) – To cut custom shapes for platforms
• Level – To ensure the structure is stable
• Miter saw or miter box with hand saw – For making angled cuts
• Scissors – For cutting fabric or carpet

These materials ensure your DIY cat tree is sturdy, comfortable, and fun for your feline friend. Now, let’s get into the step-by-step process of building your custom cat tree.

How to Build a DIY Cat Tree

Building a DIY cat tree is straightforward if you follow the right steps. Below is a detailed guide on how to construct your own, ensuring both stability and fun for your cat.

11 Steps to Build a DIY Cat Tree

Building a DIY cat tree is a great way to create a fun, comfortable, and safe space for your cat while saving money. Follow these 11 detailed steps to construct a custom cat tree that suits your home and your feline’s needs.

Step 1: Build the Base

The base is the foundation of your cat tree, so it needs to be sturdy and stable.

• Cut 2×4 wood boards into:
  • Two pieces (4 feet long)
  • Six pieces (21 inches long)
• Arrange two 4-foot pieces and two 21-inch pieces into a rectangle, placing the 21-inch pieces inside the longer ones.
• The final perimeter should be 2 feet by 4 feet.
• Add a 21-inch crosspiece in the center for additional support.
• Use a speed square to ensure corners are square.
• Screw or nail the base together securely.

This strong base ensures the cat tree doesn’t wobble when your cat jumps on it.

Step 2: Attach the Middle Post

The middle post provides stability and acts as a climbing area.

• Cut 4×4 posts to your desired heights based on your cat’s agility. (Example: 2 feet, 4 feet, and 6 feet).
• Stand the tallest post at the back intersection of the base and crosspiece.
• Secure it to the base and crosspiece using screws.
• Attach another 21-inch 2×4 next to the post—this will provide support for the floor in the next steps.

This post acts as a central support for the tree structure.

Step 3: Attach Floor Supports

Floor supports help stabilize the structure and provide a place for platforms.

• Stand the shortest post inside the base on the left side.
• Place a 21-inch 2×4 next to the post and screw it into the base.
• Repeat this step on the right side using the post as a guide.

These supports will help hold up the flooring and create climbing levels.

Step 4: Add Trim

Adding trim helps cover screws and gives a finished look.

• Cut a 4-inch-wide wooden picket to 4 feet long.
• Attach it to the front of the base to hide screws and create a clean edge.

This step enhances the visual appeal of your DIY cat tree.

Step 5: Add Posts and Flooring

Now, it’s time to add more posts and floors for climbing and resting.

• Attach a 6-inch board or wooden picket to the front as the first floor.
• Align the left-side post behind this board and secure it into the base and crosspiece.
• Add two more floorboards to create a sturdy floor section.
• Repeat the process for the right-side post to complete the flooring.

This step creates multiple levels for climbing and resting.

Step 6: Make the Shelves

Shelves provide resting areas and exciting climbing opportunities.

• Measure and cut shelves using a circular saw.
• Use a jigsaw to create rounded or freeform shapes if desired.
• If you prefer, leave shelves as rectangles or squares.

Custom shelves allow you to design a cat tree that fits your space and style.

Step 7: Add Shelf Supports

Supports keep the shelves sturdy and safe.

• Cut 2x2s and 2x4s for supports.
  • Use four 2x2s for lower shelves.
  • Use two 2x4s for the largest, highest shelf.
• Screw supports into the sides of the posts, making sure they are level.
• If desired, add picket trim to cover exposed 2x4s for a polished look.

These supports ensure that shelves stay in place even with active cats jumping on them.

Step 8: Attach and Upholster Shelves

Adding soft fabric makes the cat tree comfortable and inviting.

• Cut carpet remnants, bath mats, or fabric to match the shelf sizes.
• Before attaching, consider adding a scratcher to one of the shelves (see Step 9).
• Place each shelf onto the supports and screw them in place.
• Cover the shelves with carpet and glue it down securely.
• Use sisal trim around the shelf perimeters for a scratch-friendly edge.

This step ensures your cat has a cozy and non-slip surface to lounge on.

Step 9: Add Scratchers

Scratching posts and scratcher sections keep your cat entertained and protect your furniture.

• Wrap sisal rope around the posts at various heights.
• Start by tying a knot at the back and wrap the rope around the loose end.
• Secure it with glue or a screw to prevent unraveling.
• (Optional) Create a scratching edge on a shelf:
  • Drill ½-inch holes in a line, 1 inch from the edge.
  • Use a jigsaw to cut out segments between the holes.
  • Wrap sisal rope through the holes and around the edge.
  • Secure with glue or screws.

Adding multiple scratchers prevents your cat from clawing your furniture.

Step 10: Add Safety Anchors and Toys

Safety is important, especially if you have an active or large cat.

• Attach a 90-degree angle bracket to the top and middle shelves.
• Use drywall anchors to secure the cat tree to the wall.
• If desired, add a 2×2 brace between the tallest posts to prevent wobbling.
• Hang cat toys from the shelves using hooks.

This ensures the cat tree stays secure and fun for your feline.

Step 11: Final Checks & Let Your Cat Enjoy

Before introducing your cat to the new tree, do a final safety check.

• Make sure all screws and nails are securely in place.
• Check for any loose carpet or fabric that may need re-gluing.
• Gently shake the structure to test stability.
• Place your cat’s favorite treats or toys on the tree to encourage exploration.

Once everything looks good, let your cat explore their new playground!
