Build steps

1. 1

   Confirm Installation Location and Cat Traffic Flow

   ≈ 15 min

   Decide the installation place for the slim cat tower (350×350×1500mm). Ideal locations are near windows or along walls, at positions easy for cats to jump onto. Choose a place where it can be fixed to the wall to prevent tipping.

   Measure

   W 350 mm

   MeasureSTEP 1 / 11

   Tip

   • Maintain at least 300mm distance from the ceiling so cats cannot push off the ceiling to climb.
   • Installing near windows is preferred as a sunbathing and outside-viewing spot.
   • For multiple cats, create a refuge with height over 1500mm.

   Watch out

   • Avoid placing directly under air conditioners; direct airflow may annoy cats.
   • Avoid structures where cats cannot get down after climbing; lower base boards should be arranged in steps.
2. 2

   Cut and Prepare Components

   ≈ 25 min

   Cut four base boards (15×350×350mm) from 15mm thick Lauan plywood. Prepare two hemp rope wrapped poles φ90×1500mm and two 2×4 lumber posts (38×89×1500mm). Prepare 4.5m of φ8mm hemp rope, 40 pieces of 50mm coarse-thread screws, and three 350×350mm boa material carpets.

   Cut

   Use the in-store cut service

   CutSTEP 2 / 11

   Tip

   • 15mm Lauan plywood offers good strength-to-weight balance; 12mm cannot support the weight adequately.
   • It's faster to buy pre-wrapped hemp rope poles; available at DIY stores.
   • Choose thin carpets for easier adhesion; thick ones prevent easy claw gripping.

   Watch out

   • Thin plywood breaks on impact when cats jump on.
   • Poles made of soft materials are unstable; select ones with hardwood cores even if wrapped with hemp rope.
3. 3

   Sand All Components

   ≈ 25 min

   Sand Lauan plywood and 2×4 lumber in order from #120 to #240 grit. Cats can lick and scratch these surfaces, so absolutely no splinters. Carefully bevel corners especially.

   Sand

   #120

   SandSTEP 3 / 11

   Tip

   • Smooth all surfaces cats can touch; verify by running your fingertip over them.
   • Plywood edges (ends) are rougher than finished faces and require focused sanding.
   • Perform sanding indoors or in ventilated areas to handle dust.

   Watch out

   • Even a single splinter can injure cats' tongues or paw pads.
   • Dust adhering to carpets is hard to remove; separate sanding area from assembly space.
4. 4

   Mark Post Positions on Base Boards

   ≈ 20 min

   Mark with pencil where posts will be attached on the four base boards. The first base board (bottom) has two posts arranged in a square. Boards 2 to 4 are arranged at different heights (e.g., 300mm, 600mm, 900mm). Offset slightly from the center line for cat ease of walking, considering left-right balance.

   Mark a line

   Use a try square

   MarkSTEP 4 / 11

   Tip

   • Uneven center of gravity makes the tower easy to tip; a square base with four posts is standard.
   • Arrange boards at staggered heights as steps for cats to climb.
   • Mark centers of holes with an awl for easier drilling.

   Watch out

   • Positioning posts too close to board edges risks edge splitting when screwing.
   • Misaligned post positions on all boards cause distortion in the whole assembly; use overlay tracing for accuracy.
5. 5

   Drill Pilot Holes on Base Boards and Posts

   ≈ 20 min

   Drill φ5mm pilot holes in base boards and 2×4 posts. Use countersink bits on base boards to recess screw heads flush. For hemp rope wrapped poles, fix with metal brackets included with the product.

   Drill a hole

   φ5mm

   DrillSTEP 5 / 11

   Tip

   • Countersinking produces a neat finish and prevents claws hooking on screw heads.
   • Use a drill stopper to control hole depth and prevent through-holes.
   • Keep at least 20mm distance from the end in 2×4 lumber to avoid splitting.

   Watch out

   • Driving 50mm screws without pilot holes causes 2×4 lumber to split.
   • Excessively deep countersinks result in weak fixation where screws might come loose.
6. 6

   Assemble Bottom Board and Posts

   ≈ 30 min

   Stand two posts (hemp rope wrapped pole and 2×4 lumber) vertically on bottom board (450×450). From under the board, drive three 50mm coarse-thread screws per post (six total). Confirm verticality with a carpenter's square during work. More screws here provide strength as this board supports the most weight.

   Build the frame

   Tighten joints firmly

   AssembleSTEP 6 / 11

   Tip

   • Check verticality with a level from two directions (front and side), aiming for zero deviation.
   • Applying wood glue on contact surfaces increases rigidity when screwing from below.
   • Screw heads under the bottom board are invisible, so increase screw count without worry.

   Watch out

   • Any tilt in posts causes upper boards to be unstable, unsettling cats.
   • Insufficient screws cause posts to wobble with cat activity.
7. 7

   Attach Middle and Upper Boards

   ≈ 30 min

   Attach middle boards (at heights 300 to 900mm) horizontally to posts. Drill φ5mm pilot holes from under each board, then drive 50mm coarse-thread screws into each post (six screws per board: two posts × three screws). Use a level to ensure horizontal placement. Secure fixation strong enough to withstand cats jumping impact.

   Build the frame

   Tighten joints firmly

   AssembleSTEP 7 / 11

   Tip

   • Cats notice if boards are not level.
   • Drive screws along posts' centerlines; near edges causes splitting.
   • Consider making upper boards smaller for center of gravity.

   Watch out

   • Impact during screw driving can upset level of lower boards; after assembling all three boards, recheck horizontality.
   • Insufficient screws risk accidents from falls considering 10kg cat weight plus dynamic load.
8. 8

   Wrap Hemp Rope (Scratching Post Function)

   ≈ 30 min

   If not using pre-wrapped hemp rope poles, tightly wrap φ8mm×4.5m hemp rope around 2×4 posts, fixing ends with staples or screws. Wrap direction bottom-up, tightly and without gaps.

   Build the frame

   Tighten joints firmly

   AssembleSTEP 8 / 11

   Tip

   • Start wrapping by inserting the rope end into a hole in the post and securing with wood glue to prevent loosening.
   • Staple frequently during wrapping to prevent slack.
   • Hide the end by inserting into the same hole as start for a clean finish.

   Watch out

   • Loose rope can unravel as cats pull on it; wrap tight and fix frequently.
   • Avoid synthetic fiber ropes; cats might chew and swallow dangerous fibers.
9. 9

   Attach Carpet (Boa Material)

   ≈ 25 min

   Attach carpet pieces onto the top surfaces of three boards (upper, middle, bottom) using strong double-sided tape or wood glue. Cut carpet corners to fit board shapes with a cutter. Adhesion must endure cats’ clawing without peeling off.

   Fix to the wall

   Anchor to studs

   InstallSTEP 9 / 11

   Tip

   • Choose strong double-sided tape; normal tape peels off under cat claws.
   • Align carpet nap direction uniformly for good appearance.
   • Leave slight excess at edges and fold under for better hold.

   Watch out

   • Weak adhesion causes peels during cat play, posing ingestion risk.
   • Avoid cheap carpets with latex backing that deteriorates into powder.
10. 10

    Fix to Wall for Tip-Over Prevention

    ≈ 20 min

    Secure the upper part of the tower to the wall using L-shaped brackets and seismic straps to prevent tipping. Ensure strong fixation into wall studs detected with a stud finder. This prevents toppling during earthquakes or vigorous cat movement.

    Fix to the wall

    Anchor to studs

    InstallSTEP 10 / 11

    Tip

    • Wall fixation is safety-critical; cats jumping can easily topple a 1200mm+ tower.
    • Seismic straps can be obtained cheaply but specialized products from home centers offer more reliability.
    • Do not anchor into gypsum board alone; always fix into studs.

    Watch out

    • Omitting wall fixation risks tower falling during earthquake, injuring cats.
    • Check bracket load ratings to support combined tower weight, cat load, and seismic forces.
11. 11

    Final Check and Introduce Cat

    ≈ 15 min

    Check tightness of all screws, carpet adhesion, and post stability. Place the tower in the final spot and verify levelness. If wobbling occurs, fix with felt pads under feet. Before introducing cats, shake the tower strongly to confirm stability.

    Done!

    Done — nice work!

    DoneSTEP 11 / 11

    Tip

    • Placing cat treats on boards right after completion helps cats approach without fear.
    • Do not force cats onto the tower initially; let them explore naturally.
    • Placing other furniture nearby to form 'steps' helps cats climb up easily over several days.

    Watch out

    • Incomplete final checks may cause cat injuries due to assembly faults.
    • 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.
• ⚠️Tighten all joints securely to support the cat's weight.
