Quick answer: To anchor a tall DIY cat tower in an apartment, find a wall stud or use a fixing rated for your wall type, attach a metal L-bracket or furniture strap to the upper third of the tower, and pull it snug against the wall. Check your lease first, test by pushing the top firmly, and recheck screws every month.
A tall cat tower is great for climbing cats, but height brings tipping risk. Cats leap onto and off top platforms with real force. An anchor turns a tall freestanding tower into one held by the building itself.
This checklist walks through each step for apartments, where walls, leases and neighbours add a few extra considerations. For base design, see our cat tree stability guide.
Work through the steps in order and tick each one off before letting a cat climb.
Our DIY cat tree hub links the full build guides if you have not built the tower yet.
Step 1: Decide whether the tower needs anchoring
As a simple rule, anchor any tower that is taller than about three times the width of its base, any tower with platforms overhanging the base, and any tower used by kittens, large cats or more than one cat. If in doubt, anchor it. The CPSC Anchor It campaign explains why tall furniture in homes should be secured against tipping.
Why tall towers tip
A cat tower tips when the force at the top, multiplied by the height, overcomes the weight of the tower acting over the width of its base. Tall towers have a long lever arm, and cats apply force exactly at the top: landing, launching, scratching and play-fighting. A cat that weighs 5 kg can push with several times that force for a split second when it jumps. Even a tower that feels solid when you lean on it gently can move under that load. An anchor adds a fixing at the top, where the force is greatest, so the tower cannot lean far enough to fall.
Our cat tree height guide explains how tall a tower really needs to be for different cats.
Step 2: Check your lease
Read the lease section on alterations and wall fixings. Many leases allow small screws for pictures and furniture safety straps, provided you fill the holes when you leave. Some require written permission. Send a short message to your landlord describing the fixing and its purpose. Keeping a record protects your deposit.
Step 3: Identify your wall type
Apartments may have plasterboard on timber or metal studs, solid brick or concrete, or older lath and plaster. Knock on the wall: a hollow sound suggests plasterboard; a dull solid sound suggests masonry. A stud finder helps locate timber or metal studs. Each wall type needs different fixings.
Step 4: Choose the right fixing
| Wall type | Suitable fixing | Notes |
|---|---|---|
| Plasterboard on timber stud | Wood screw into stud | Best option; locate stud centre |
| Plasterboard, no stud | Heavy-duty hollow wall anchor | Check the rating on the packet |
| Brick or concrete | Masonry plug and screw | Use a masonry drill bit |
| Metal stud | Self-drilling screw or toggle | Follow the anchor's instructions |
Our stud-free anchoring guide covers options when a stud is not where you need it.
Step 5: Choose the hardware
Metal L-brackets give a rigid fixing and suit towers that stand right against the wall. Furniture safety straps, usually a webbing or steel cable with brackets on each end, allow a small gap and are easier to fit and remove. Either works if fitted securely. Choose hardware designed for anti-tip use rather than general hooks.
Step 6: Find the fixing point on the tower
Attach the anchor to the upper third of the tower, on the main post or a solid frame member, not a thin platform or carpeted panel. The higher the anchor, the better it resists tipping. Screw into solid wood with screws long enough to grip well.
Step 7: Fit the anchor
Mark the wall position level with the tower fixing point. Drill a pilot hole, insert the plug or anchor if needed and fix the wall bracket. Attach the tower bracket. Connect the strap or bracket and pull it snug so the tower cannot lean forward. Avoid over-tightening, which can pull the tower off vertical.
Step 8: Test it properly
Push the top platform firmly forward, sideways and back. The tower should not tip forward at all and should barely move. Press down on platform edges. Check that the wall fixing has not moved. Repeat after a day and again after a week, because fixings can settle.
Step 9: Protect cats from the hardware
Make sure straps are tight enough that a cat cannot get a paw or head caught behind them. Cover sharp bracket edges with tape or a small cap. Keep spare screws and plugs away from cats; small parts can be swallowed. VCA guidance on foreign bodies in cats explains why small objects are a risk.
Step 10: Monthly checks
Each month, tighten screws on the tower and the anchor, inspect straps for fraying and check the wall for cracks around the fixing. Look for loose platforms, too. Our wobbly cat tree fixes guide covers repairs.
Placement that supports the anchor
Corners are ideal, because the tower can be anchored to one wall and braced by another. Keep the tower away from windows that open, balcony doors and radiators. Leave a landing area in front. Our corner cat tree ideas show compact layouts.
Noise and shared walls
In apartments, anchoring to a shared wall can pass knocks and thuds to neighbours. Use a rubber washer between the bracket and wall, and choose a strap rather than a rigid bracket if noise is a concern.
Moving out
When you move, remove the anchor, fill the hole with filler, sand it smooth and touch up the paint. Keep the hardware with the tower so you can anchor it again in your next home.
Special cases
Older cats and cats with arthritis may land awkwardly, so anchoring matters even for moderate heights; VCA guidance on arthritis in cats describes signs of joint pain. Multi-cat households put more load on towers, so anchor every tall tower.
Tools you will need
Most anchors need only a few tools: a stud finder or a small magnet to locate screws in plasterboard, a pencil, a spirit level, a drill with wood and masonry bits, a screwdriver and the fixings themselves. A second person helps hold the tower upright while you mark positions. Lay a towel on the floor to catch dust, and vacuum afterwards so cats do not walk through it. If you are not comfortable drilling, a handyperson can fit an anchor quickly, and it is worth the small cost for a tall tower.
What if you cannot anchor at all
Some leases forbid any wall fixing, and some walls are unsuitable. In that case, reduce the risk in other ways. Lower the tower, or remove the top platform. Add weight to the base with a sealed slab fixed underneath. Place the tower in a corner, so two walls limit how far it can lean. Choose a wider base. Our temporary cat tree solutions guide covers more options for strict leases. A shorter, heavier tower is a better choice than a tall one that cannot be secured.
Signs an anchor is failing
Watch for a gap opening between the strap bracket and the wall, a screw head standing proud, cracks in plaster around the fixing, a strap that has gone slack or a tower that has started to lean. Any of these means the anchor needs attention before the next climb. Tighten, refix in a new hole or move to a stud. Never ignore a loose anchor, because a tower that is partly held can swing in a way that surprises a cat.

FAQ: Anchoring a Tall DIY Cat Tower
Do I need to anchor a cat tower?
Anchor tall or slim towers, towers with overhanging platforms and towers used by active or multiple cats.
Can I anchor without drilling?
Some tension systems work, but a screwed fixing is more secure. See our stud-free options.
Where should the anchor attach?
To the upper third of the tower, on a solid post or frame.
What if I hit no stud?
Use a heavy-duty hollow wall anchor rated for the load, or move the tower to a stud.
How often should I check the anchor?
Monthly, and after moving the tower.
