Materials

Build steps

1. 1

   Confirm installation location and cat's moving path

   ≈ 15 min

   Decide on the installation spot for the wall-mounted cat step (400×250×200mm). Ideal locations are near windows or along walls where cats can easily jump. Choose a spot where it can be secured to the wall to prevent tipping over.

   Measure

   W 400 mm

   MeasureSTEP 1 / 11

   Tip

   • Leave at least 300mm space from the ceiling to prevent the cat from pushing and climbing the ceiling.
   • Installation near windows is preferred for sunbathing and outside viewing.
   • If you have multiple cats, create escape space by having heights 200mm or more apart.

   Watch out

   • Avoid installing directly below air conditioners as drafts may bother cats.
   • Avoid designs where cats climb high and cannot get down. Arrange base boards in a stepped manner.
2. 2

   Cut and prepare parts

   ≈ 25 min

   Cut one base board (15×250×400mm) from 15mm thick Lauan plywood. Prepare support posts: one hemp rope wrapped pole φ90×200mm, one 2×4 lumber (38×89×200mm), one meter of φ8mm hemp rope, forty 50mm coarse-thread screws, and one piece of boa material carpet (250×400mm).

   Cut

   Use the in-store cut service

   CutSTEP 2 / 11

   Tip

   • 15mm Lauan plywood balances strength and lightness well. 12mm is not sufficient to support weight.
   • Purchasing a premade hemp rope wrapped pole is faster; available at DIY stores.
   • Thin carpets are easier to attach; thick ones may not catch claws well.

   Watch out

   • Using thin plywood may crack from impact when cats jump.
   • Soft-core poles are unstable. Choose poles with hardwood cores even when wrapped with hemp rope.
3. 3

   Sand all parts

   ≈ 25 min

   Sand the Lauan plywood and 2×4 lumber in order: #120 grit then #240 grit. Since cats lick and scratch, avoid any splinters. Carefully bevel edges.

   Sand

   #120

   SandSTEP 3 / 11

   Tip

   • Make all cat-contact surfaces smooth; check by stroking with your finger pad.
   • Plywood edges are rougher than surfaces; sand these thoroughly.
   • Perform sanding indoors or in ventilated areas to manage dust.

   Watch out

   • Even a single splinter can injure a cat’s tongue or paw pads.
   • Dust sticking to carpet is hard to remove; use separate work areas.
4. 4

   Mark support post locations on base boards

   ≈ 20 min

   Mark with pencil where the support posts attach on the four base boards. For base board 1 (bottom board), arrange two posts in a square formation. For base boards 2 to 4, set at increasing heights (e.g. 300mm, 600mm, 900mm). Offset slightly from center line for easier cat walking.

   Mark a line

   Use a try square

   MarkSTEP 4 / 11

   Tip

   • Off-center base boards are prone to tipping; four posts in a square base are standard.
   • Arrange base boards at different heights as steps for easy cat climbing.
   • Mark hole centers clearly with a punch to facilitate drilling.

   Watch out

   • Placing support posts too close to board edges causes splitting when screwing.
   • Misaligned post positions on boards cause overall distortion; use overlay transfer for accuracy.
5. 5

   Drill pilot holes in base boards and support posts

   ≈ 20 min

   Drill φ5mm pilot holes in base boards and 2×4 lumber support posts. Use a countersink bit on base boards to recess screw heads flush. For hemp rope wrapped poles, use included metal brackets and hardware for attachment.

   Drill a hole

   φ5mm

   DrillSTEP 5 / 11

   Tip

   • Countersinking produces a clean finish, preventing claw snagging on screw heads.
   • Use drill stoppers to control hole depth and prevent drilling through.
   • Keep pilot holes in 2×4 lumber at least 20mm from edges to prevent splitting.

   Watch out

   • Driving 50mm screws without pilot holes causes lumber splitting.
   • Over-countersinking weakens screw holding strength.
6. 6

   Assemble bottom board and support posts

   ≈ 30 min

   Stand two posts (hemp rope wrapped pole and 2×4 lumber) vertically on the bottom board (450×450). From the underside of the board, drive three 50mm coarse-thread screws into each post (total six screws). Check verticality with a square during assembly. Use more screws here as the bottom board supports most weight.

   Build the frame

   Tighten joints firmly

   AssembleSTEP 6 / 11

   Tip

   • Check post verticality with a level from two directions (front and side) aiming for zero deviation.
   • Apply wood glue on joint surfaces before screwing for increased rigidity.
   • Screw heads on the underside of the bottom board can be numerous since not visible.

   Watch out

   • Even slight tilt of posts results in instability on upper boards.
   • Insufficient number of screws causes posts to wobble from cat movement.
7. 7

   Attach middle and upper base boards

   ≈ 30 min

   Attach middle base boards (heights 300~900mm) horizontally to the posts. Drill φ5mm pilot holes under base boards and drive 50mm coarse-thread screws into posts (6 screws per base board, 3 screws per post). Confirm horizontality with a level. Ensure fastening is strong enough to withstand impact from cats jumping.

   Build the frame

   Tighten joints firmly

   AssembleSTEP 7 / 11

   Tip

   • Non-level boards cause cats discomfort.
   • Drive screws centered on the posts; screws near edges may cause splitting.
   • Reducing size of boards toward the top helps maintain balance.

   Watch out

   • Screw impact may tilt lower boards; confirm horizontal alignment after assembly of all three levels.
   • Insufficient screws directly increase risk of falls; design load for 10kg cat plus dynamic loads.
8. 8

   Wrap hemp rope on 2×4 post (scratching post function)

   ≈ 30 min

   If not using a premade hemp rope wrapped pole, tightly wrap φ8mm hemp rope (1m) around the 2×4 post. Fix both ends with staples or screws. Wrap from bottom to top, tightly and without gaps.

   Build the frame

   Tighten joints firmly

   AssembleSTEP 8 / 11

   Tip

   • Start wrapping by inserting rope into a hole drilled in the post, affix with wood glue to secure.
   • Staple periodically while wrapping to prevent loosening.
   • Hide the end by tucking into the same hole for a neat finish.

   Watch out

   • Loose rope unwinds when cats pull. Wrap tightly and fix often.
   • Avoid synthetic fiber ropes as cats may chew and ingest harmful materials.
9. 9

   Attach carpet (boa material)

   ≈ 25 min

   Attach carpet to the top surface of three base boards (top, middle, base) using double-sided tape or wood glue. Trim carpet corners with a cutter to fit the board shape. Use adhesive strong enough to resist cat clawing.

   Fix to the wall

   Anchor to studs

   InstallSTEP 9 / 11

   Tip

   • Use strong type double-sided tape; regular tape peels off from cat claws.
   • Align carpet nap direction for better appearance.
   • Leave a small margin at edges and fold back underneath for stronger adhesion.

   Watch out

   • Weak adhesion causes carpet to peel off during play, posing ingestion hazard.
   • Avoid carpets with latex backing that breaks down and sheds dust.
10. 10

    Wall fixing to prevent tipping

    ≈ 20 min

    Secure the tower top to the wall using L brackets and seismic straps to prevent tipping. Fix firmly to wall studs following position confirmation with stud sensor. This safeguards against earthquakes or intense cat movements.

    Fix to the wall

    Anchor to studs

    InstallSTEP 10 / 11

    Tip

    • Wall fixing is mandatory for safety; a 1200mm high tower easily tips when cats jump on it.
    • Seismic straps can be found at 100-yen shops; specialized ones at hardware stores offer more reliability.
    • Drywall alone cannot hold mounts; secure into wall studs only.

    Watch out

    • Omitting wall fixing risks collapse during earthquakes and cat injuries.
    • Check load capacities of hardware; must support tower weight plus cat weight plus shock loads.
11. 11

    Final check and introduction to cat

    ≈ 15 min

    Check all screws are tight, carpets are adhered securely, and posts have no wobble. Set the structure in place and confirm level. If shaky, add felt pads to feet for adjustment. Shake gently to confirm stability before letting cats use.

    Done!

    Done — nice work!

    DoneSTEP 11 / 11

    Tip

    • Place cat treats on boards at first to reduce cat anxiety about climbing.
    • Do not force cats to climb on first day; allow natural exploration.
    • Place nearby furniture as
    • stairs
    • to encourage climbing.

    Watch out

    • Neglecting final inspection can cause injuries from assembly failures.
    • If cats avoid using it, it may be due to poor location or scent; observe for a while.

Warnings

• ⚠️Drill pilot holes before screwing to prevent wood splitting.
• ⚠️When fixing to the wall, always locate a stud (do not fix to drywall alone).
