Materials

Build steps

1. 1

   Confirm installation location and cat's traffic flow

   ≈ 15 min

   Decide the installation location for the shelf board style cat walk (500×250×200mm). Ideal spots are near windows or along walls, where cats can easily jump on. Choose a location that allows fixing to the wall to prevent tipping over.

   Measure

   W 500 mm

   MeasureSTEP 1 / 11

   Tip

   • Maintain a distance of at least 300mm from the ceiling to prevent the cat from pushing against and climbing the ceiling.
   • Installation near windows is preferred as a spot for sunbathing or viewing outside.
   • If housing multiple cats, create escape spots by placing platforms at heights of 200mm or more.

   Watch out

   • Avoid placing directly under an air conditioner. Cats dislike direct cold air.
   • Avoid structures where cats can climb high but cannot get down; ensure lower base boards are arranged in steps.
2. 2

   Cut and prepare materials

   ≈ 25 min

   Cut one base board (15×250×500mm) from 15mm lauan plywood. Prepare one hemp rope wrapped pole (φ90×200mm) and one 2×4 lumber post (38×89×200mm). Prepare 1m of φ8mm hemp rope, 40 pieces of 50mm coarse-thread screws, and one carpet (boa material) 250×500mm.

   Cut

   Use the in-store cut service

   CutSTEP 2 / 11

   Tip

   • 15mm lauan plywood balances strength and lightness well. 12mm thickness cannot support the weight adequately.
   • Purchasing pre-made hemp rope wrapped poles is faster; available at DIY stores.
   • Choose thin carpet for easier adhesion. Thick carpet is harder for cats to hook their claws into.

   Watch out

   • Using thin plywood risks cracking under the impact of cats jumping on.
   • Soft post cores are unstable. Choose hardwood cores even if wrapped with hemp rope.
3. 3

   Sand all materials

   ≈ 25 min

   Sand the lauan plywood and 2×4 lumber in order from #120 grit to #240 grit. Since cats may lick or scratch surfaces, splinters are absolutely unacceptable. Pay special attention to chamfering corners smoothly.

   Sand

   #120

   SandSTEP 3 / 11

   Tip

   • Smooth all parts the cat will touch; check by rubbing with the pads of your fingers.
   • Edges of plywood cross-sections are rougher than finished surfaces; concentrate on sanding these.
   • Perform sanding indoors or in a well-ventilated area to manage dust.

   Watch out

   • Even a single splinter can injure a cat's tongue or paw pads.
   • Dust settling on the carpet is difficult to remove; use separate areas for sanding and carpet work.
4. 4

   Mark post positions on base boards

   ≈ 20 min

   Mark screw positions for posts on all four base boards with pencil. For base board 1 (bottom), arrange two posts in a square layout. For base boards 2 to 4, arrange posts at different heights (e.g., 300mm, 600mm, 900mm). Offset slightly from the centerline of the boards for better cat walking balance.

   Mark a line

   Use a try square

   MarkSTEP 4 / 11

   Tip

   • Uneven weight distribution makes the structure prone to tipping; use a square base shape with four posts.
   • Arrange the boards in stair-step formation to make climbing easier for the cat.
   • Using a punch to mark hole centers makes drilling easier.

   Watch out

   • Placing post positions too close to edges can cause splitting when screws are driven.
   • Misaligned post positions on all boards cause overall distortion; ensure precise transfer by stacking and tracing.
5. 5

   Drill pilot holes in base boards and posts

   ≈ 20 min

   Drill φ5mm pilot holes in the base boards and 2×4 lumber posts. On the base boards, countersink with a countersink bit so screw heads are flush. For the hemp rope wrapped poles, use metal brackets included with the product for screw fastening.

   Drill a hole

   φ5mm

   DrillSTEP 5 / 11

   Tip

   • Countersinking gives a clean finish and prevents cats from catching claws on screw heads.
   • Use a drill stop to control hole depth and prevent through-holes.
   • Keep pilot holes at least 20mm from the edge in 2×4 lumber to prevent splitting.

   Watch out

   • Driving 50mm screws without pilot holes will split the 2×4 lumber.
   • Too deep countersinking weakens screw holding strength.
6. 6

   Assemble bottom board and posts

   ≈ 30 min

   Stand the two posts (hemp rope wrapped pole and 2×4 lumber) vertically on the bottom board (450×450). Drive three 50mm coarse-thread screws into each post from the underside of the board (6 screws total). Use a carpenter's square to confirm vertical alignment during assembly. Add extra screws on the bottom board as it bears the most weight.

   Build the frame

   Tighten joints firmly

   AssembleSTEP 6 / 11

   Tip

   • Check verticality of posts with a level in two directions (front and side), aiming for zero level deviation.
   • Apply wood glue on contact surfaces to increase rigidity when driving screws.
   • Since the underside of the bottom board is hidden, increase screw count without concern about screw head appearance.

   Watch out

   • Even slight leaning in posts causes upper boards to tilt, making cats uneasy.
   • Insufficient screws cause posts to wobble from cat movement.
7. 7

   Attach middle and upper boards

   ≈ 30 min

   Attach the middle boards (heights 300~900mm) horizontally to posts. Drill φ5mm pilot holes from underside of boards and drive 50mm coarse-thread screws into posts (6 screws per board: 2 screws per post × 3 posts). Check level to ensure each board is horizontal. Secure joints to withstand impact when cats jump on them.

   Build the frame

   Tighten joints firmly

   AssembleSTEP 7 / 11

   Tip

   • Cats sense discomfort if boards are not level.
   • Screw into the centerline of posts; screwing too close to edges causes splitting.
   • Consider tapering boards smaller at higher levels to adjust the center of gravity.

   Watch out

   • Driving screws may affect level of lower boards; recheck level after assembling all three boards.
   • Insufficient screws directly cause risk of falls; account for cats up to 10kg plus dynamic loads.
8. 8

   Wrap hemp rope for scratching post function

   ≈ 30 min

   If not using a pre-wrapped hemp rope pole, tightly wrap 1m of φ8mm hemp rope around the 2×4 post from bottom to top. Fix both ends with staples or screws. Avoid gaps by wrapping densely.

   Build the frame

   Tighten joints firmly

   AssembleSTEP 8 / 11

   Tip

   • Start rope wrap by inserting it into a drilled hole and securing with wood glue to prevent loosening.
   • Staple frequently during wrapping to keep rope tight.
   • Hide the end by inserting it in the same hole to achieve a neat finish.

   Watch out

   • Loose rope unravels as cats pull at it; wrap tightly and fix frequently.
   • Avoid synthetic fiber ropes as cats may chew and ingest harmful materials.
9. 9

   Adhere carpet (boa material)

   ≈ 25 min

   Attach carpet to top surfaces of three boards (upper, middle, base) using double-sided tape or wood glue. Cut carpet corners with a cutter to match board shape. Ensure adhesion strength to resist peeling by cat claws.

   Fix to the wall

   Anchor to studs

   InstallSTEP 9 / 11

   Tip

   • Choose strong double-sided tape; regular tape peels under cat claw force.
   • Align carpet nap direction uniformly for better appearance.
   • Leave some extra carpet at edges and fold underside for better adhesion and durability.

   Watch out

   • Weak adhesion risks carpet coming off during play, posing ingestion hazards.
   • Avoid cheap carpets with latex backing that degrade into powder.
10. 10

    Fix to wall to prevent tipping

    ≈ 20 min

    Fix the top of the tower to the wall using L-brackets and earthquake-resistant belts to prevent tipping. Secure firmly into wall studs confirmed by stud finder. This prevents falling during earthquakes or vigorous cat movement.

    Fix to the wall

    Anchor to studs

    InstallSTEP 10 / 11

    Tip

    • Wall fixation is essential for safety; cats jumping can easily topple a 1200mm high tower.
    • Earthquake-resistant belts are available in 100-yen shops; specialized belts from home centers are more reliable.
    • Do not fix only to gypsum board; always secure to wall studs.

    Watch out

    • Omitting wall fixation risks tower falling during earthquakes, causing injury to cats.
    • Confirm bracket load capacity; it must support tower weight plus cat weight and seismic forces.
11. 11

    Final inspection and cat introduction

    ≈ 15 min

    Check all screws are tight, carpet is secured, and posts have no wobble. Place the tower in installation location and check level with a level tool. If unstable, apply felt pads to the feet to adjust. Before introducing cats, shake the tower strongly to check stability.

    Done!

    Done — nice work!

    DoneSTEP 11 / 11

    Tip

    • Placing cat treats on boards immediately after completion encourages cats to climb without fear.
    • Do not force cats to mount on first day; allow natural exploration.
    • Place nearby furniture to create a 'stairway' to help cats climb over a few days.

    Watch out

    • Poor checks and assembly may cause injury to cats; final inspection must be thorough.
    • If cats do not climb, location or scent may be unsuitable; observe for some time.

Warnings

• ⚠️Drill pilot holes before driving screws to prevent wood splitting.
• ⚠️Ensure all joints are securely tightened to withstand the cat's weight.
