Materials

Build steps

1. 1

   Confirm installation location and cat's movement path

   ≈ 15 min

   Decide the installation spot for the mini cat walk (350×200×200mm). Ideally near a window or along a wall where the cat can easily jump on. Choose a location where it can be fixed to the wall to prevent tipping over.

   Measure

   W 350 mm

   MeasureSTEP 1 / 11

   Tip

   • Leave at least 300mm between the top and ceiling to prevent the cat from pushing and climbing the ceiling.
   • Installing near a window is favored for sunbathing and viewing outside.
   • For multiple cats, create escape spaces by placing platforms at heights of 200mm or more.

   Watch out

   • Avoid direct air conditioner blows as cats dislike it.
   • Avoid structures from which cats cannot climb down; platforms should be arranged stepwise.
2. 2

   Cut and prepare materials

   ≈ 25 min

   Cut one platform board (15×200×350mm) from 15mm thick meranti plywood. Prepare one hemp rope wrapped pole post (φ90×200mm), one 2x4 lumber post (38×89×200mm), 1m of φ8mm hemp rope, forty 50mm coarse-thread screws, and one carpet piece (boa material) 200×350mm.

   Cut

   Use the in-store cut service

   CutSTEP 2 / 11

   Tip

   • 15mm meranti plywood offers a good balance of strength and lightness; 12mm is insufficient to support weight.
   • It’s faster to purchase a hemp rope wrapped pole as a ready-made product, available at DIY stores.
   • Thin carpets are easier to attach; thick ones hinder nail scratching.

   Watch out

   • Using thin plywood risks cracking from the impact of the cat jumping.
   • Posts made of soft material are unstable; choose hardwood core wrapped with hemp rope.
3. 3

   Sand all materials

   ≈ 25 min

   Sand the meranti plywood and 2x4 lumber starting with #120 grit, then #240 grit. Since cats lick and scratch, avoid any splinters, especially carefully chamfer edges.

   Sand

   #120

   SandSTEP 3 / 11

   Tip

   • Smooth all surfaces the cat will touch; verify by running the pad of your finger.
   • Plywood edges are rougher than the surface; focus sanding there.
   • Perform sanding indoors or in ventilated areas to control dust.

   Watch out

   • Even one splinter can injure a cat’s tongue or paw pads.
   • Dust clinging to the carpet is difficult to remove; keep work areas separate.
4. 4

   Mark post positions on platform boards

   ≈ 20 min

   Mark with pencil the positions to attach posts on four platform boards. The base platform places two posts in a square layout. The upper platforms are arranged stair-stepwise by height (e.g., 300mm, 600mm, 900mm). Offsetting slightly from the centerline on each board improves cat walking comfort.

   Mark a line

   Use a try square

   MarkSTEP 4 / 11

   Tip

   • If the center of gravity is off, the structure tips easily; a square base with four posts is basic.
   • Arranging platforms in stair-step fashion helps cats climb.
   • Use an awl to clearly mark hole centers, making drilling easier.

   Watch out

   • Positioning posts too close to the edge causes edge splitting when screwing.
   • Misaligned post positions distort the entire structure; accurately transfer marks by stacking.
5. 5

   Drill pilot holes on platform boards and posts

   ≈ 20 min

   Drill φ5mm pilot holes on the platform boards and 2x4 posts. On platform boards, add countersinking with a countersink bit so screw heads sit flush. Use metal brackets included with the hemp rope wrapped pole to attach it.

   Drill a hole

   φ5mm

   DrillSTEP 5 / 11

   Tip

   • Countersinking creates a neat finish and prevents cats from scratching on screw heads.
   • Use a drill stopper to control hole depth and prevent through-holes.
   • Keep pilot holes on 2x4 posts at least 20mm from edges to avoid splitting.

   Watch out

   • Driving 50mm screws without pilot holes causes splitting in 2x4 posts.
   • Countersinks that are too deep reduce joint strength, causing screw loosening.
6. 6

   Assemble base platform and posts

   ≈ 30 min

   Stand two posts (hemp rope wrapped pole and 2x4 lumber) vertically on the base platform (450×450), then drive three 50mm coarse-thread screws into each post from the platform’s underside (6 screws total). Use a carpenter’s square to confirm verticality. Use more screws here as this base bears the greatest load.

   Build the frame

   Tighten joints firmly

   AssembleSTEP 6 / 11

   Tip

   • Confirm post verticality in two directions (front and side) with a level aiming for zero deviation.
   • Apply wood glue on joints before screwing to increase rigidity.
   • Since the underside of the base platform is hidden, more screws can be used without cosmetic concern.

   Watch out

   • Even slight post tilt causes upper platforms to lean, making cats uneasy.
   • Insufficient screw quantity allows post wobbling from cat movements.
7. 7

   Attach mid and top platform boards

   ≈ 30 min

   Attach mid-level platforms (heights 300mm to 900mm) horizontally to posts. Drill φ5mm pilot holes from underside and drive 50mm coarse-thread screws (6 per platform: 3 per post, 2 posts). Use a level to ensure platforms are horizontal. Ensure fixing strength withstands impacts from cats jumping.

   Build the frame

   Tighten joints firmly

   AssembleSTEP 7 / 11

   Tip

   • Uneven platforms cause cats discomfort.
   • Drive screws along the post's centerline; positioning screws near edges risks splitting.
   • Reducing platform size towards the top can improve center of gravity.

   Watch out

   • Screwing impacts may disturb the horizontal alignment of lower platforms; after assembling three levels, recheck levels overall.
   • Insufficient screw counts risk falling accidents; design for 10kg cat weight 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 2x4 post from bottom to top. Fix both ends with staples or screws. Avoid gaps by wrapping tightly without space.

   Build the frame

   Tighten joints firmly

   AssembleSTEP 8 / 11

   Tip

   • Start by drilling a hole in post to tuck in the rope end, securing with wood glue for durability.
   • Staple regularly while wrapping to prevent loosening.
   • Tuck the rope end back into the starting hole for neatness.

   Watch out

   • Loose rope unravels when pulled by cats; wrap tightly and fix frequently.
   • Avoid synthetic fiber ropes; cats may chew and ingest them.
9. 9

   Attach carpet (boa material)

   ≈ 25 min

   Attach carpet pieces to the top surfaces of three platform boards (top, mid, base) using double-sided tape or wood glue. Trim carpet edges with a cutter to fit the platform shape. Fix firmly to prevent peeling under cat scratching.

   Fix to the wall

   Anchor to studs

   InstallSTEP 9 / 11

   Tip

   • Use strong double-sided tape resistant to cat claws peeling off.
   • Align carpet pile direction for good appearance.
   • Leave extra carpet edges, fold under the platform for stronger adhesion.

   Watch out

   • Weak adhesion risks peeling during play and ingestion hazard.
   • Avoid cheap carpets with latex backing that degrade to powder.
10. 10

    Fix to wall to prevent tipping

    ≈ 20 min

    Secure the upper part of the tower to the wall with L-brackets and seismic straps to avoid tipping. Confirm attachment points on wall studs using a stud finder. Fix firmly to withstand earthquakes and vigorous cat movements.

    Fix to the wall

    Anchor to studs

    InstallSTEP 10 / 11

    Tip

    • Wall fixing is essential for safety; a 1200mm tall tower can easily tip if not secured.
    • Seismic straps are inexpensive at 100-yen stores; dedicated ones from home centers (~1000 yen) are more reliable.
    • Fix into wall studs, as gypsum board alone can’t support loads.

    Watch out

    • Skipping wall fixing risks collapse and traps cats under towers during earthquakes.
    • Check bracket load capacity to support the total weight plus cats and seismic forces.
11. 11

    Final inspection and cat introduction

    ≈ 15 min

    Check all screws are tight, carpets firmly attached, and posts stable. Place unit in installation spot and confirm levelness with a level. Adjust any wobble by attaching felt pads under feet. Before introducing the cat, shake unit strongly to verify stability.

    Done!

    Done — nice work!

    DoneSTEP 11 / 11

    Tip

    • Placing treats on platforms encourages cautious cats to climb.
    • Don’t force cats to climb initially; let them explore naturally.
    • Place other furniture nearby as steps to the tower to facilitate climbing for a few days.

    Watch out

    • Incomplete checks lead to injuries from poor assembly; inspect carefully.
    • If cats avoid climbing, location or scent may be unsuitable; observe for a while.

Warnings

• ⚠️Drill pilot holes before driving screws to prevent wood splitting.
• ⚠️Tighten all joints securely to support the cat's weight.
