Cat trees: what to check before you buy

Cat trees look interchangeable in listing photos. They are not. Two towers at the same price and the same advertised height can differ by five kilos of base weight and half the sisal thickness, and only one of them will still be standing straight in a year.

This page works through the specifications in the order they matter: stability first, because a wobbly tree is abandoned within days; then post height and sisal, because scratching is the point; then platform size; then the extras that marketing leads with.

1. Stability: base width and total weight

A wide, heavy base is the single biggest factor in whether a tall tree tips or stays rock solid. Cats do not step onto platforms. They launch, land, and push off again, and each of those movements applies a sideways force at the top of a lever.

What to look for:

• Base footprint of at least 50 × 50 cm for a tree up to 120 cm tall, and 70 × 70 cm or more once you pass 150 cm.
• Base board thickness of 15 mm or more. Thin particleboard flexes, and flex at the base becomes a visible sway at the top perch.
• Shipping weight as a proxy. A 150 cm tree that ships at 12 kg is built from denser material than an identical-looking one at 7 kg.
• A wall strap included in the box for anything above 160 cm, or any tree going on carpet, which is softer and less forgiving than hard floor.

2. Height: how tall a cat tree should be

Height is what cats are buying. Vertical space is how a cat manages territory, avoids the dog, escapes a toddler and watches the street. A tree that only reaches sofa height offers nothing the sofa does not.

Most domestic cats settle at between 120 and 160 cm, which is no accident — that band covers windowsills, kitchen counters, bookshelf tops and wardrobe tops. The tree competes with those spots, so it needs to match them.

• Under 90 cm: kittens, senior cats and arthritic cats. Also a sensible second tree for a multi-cat home.
• 120–160 cm: the standard adult range, and where most well-built trees sit.
• Above 180 cm or floor-to-ceiling: excellent for confident climbers, but only with a wide base or a tension-fit ceiling brace.

One caveat that gets missed: an older cat that loved a tall tree at five may not manage it at twelve. Trees with evenly spaced steps of roughly 30 cm stay usable far longer than trees with one big leap between levels.

3. Sisal: thickness beats surface area

Natural sisal is the most durable and satisfying scratching surface for most cats, and it beats carpet on every measure that matters. Carpet mats down, hides claw sheaths, and quietly teaches a cat that carpet is fair game — which is a problem if you own stairs.

Two forms are common:

• Sisal rope wound around a cardboard or wooden core. Look for 6 mm or thicker. At 3–4 mm the rope shreds under daily use and starts unwinding at the top. Winding should be tight, with no visible gaps between turns.
• Sisal fabric wrapped and stapled to the post. More expensive, noticeably longer-lived, and it does not unravel when a single strand breaks.

Post length matters as much as material. A cat scratches to stretch, so it needs to reach up with its front paws fully extended and claws above shoulder height. That means at least 60 cm of uninterrupted post for an average adult, and closer to 75 cm for a large breed. A tree with eight short 30 cm posts offers less real scratching than one with two long ones.

4. Platforms, hammocks and condos

Cats sleep curled or stretched, and a platform that only accommodates the curl gets used half as often. Measure your cat lying flat, nose to base of tail, and use that as the minimum diameter.

Beyond size, three features earn their place:

• A raised lip or edge on the top perch. Cats sleep against a rim; a flat disc feels exposed.
• One enclosed cubby low down. Nervous cats and new arrivals want a hiding spot at ground level, not at height.
• A hammock slung between posts. Older cats favour these because there is no climb, and the fabric holds body heat.

Dangling toys on elastic are the feature most likely to be photographed and least likely to matter. They are chewed off within a month.

Cat trees for large breeds

Maine Coons, Ragdolls, Savannahs, Norwegian Forest Cats, Siberians and Chausies routinely reach 7–10 kg, and the standard cat tree is designed around a 4 kg cat. The failure mode is not dramatic collapse; it is a slow lean, a platform that sags at one edge, and a cat that quietly stops using it.

For a cat over 7 kg, treat these as hard requirements:

• Platforms 40–50 cm across, so the cat can lie fully stretched without a limb hanging.
• Posts of 9 cm diameter or more, with a solid wood or thick-wall cardboard core rather than a hollow tube.
• A base of 70 × 70 cm minimum, and a stated weight capacity above 10 kg.
• Bolted, not dowelled, joints. Screw-in poles that thread into a metal insert stay tight; glued dowels loosen.
• Wider entry holes on cubbies. A 20 cm opening that fits a domestic shorthair does not fit a Maine Coon's shoulders.

If you are matching furniture to a specific breed, the cat breeds list gives adult weight ranges for 75 breeds, which is the number you actually need here.

Where to put it

Placement decides use more often than price does. The best-built tree in a spare bedroom loses to a mediocre one by a living room window.

• Against a window with something to watch — a bird feeder, a street, a garden.
• In an occupied room. Cats want to observe their household, not be filed away from it.
• Near the furniture already being scratched. Moving the target one metre from the sofa arm works far better than putting it in another room and hoping.
• Not next to the litter tray or food bowls. Cats keep those zones separate.

If a cat ignores a new tree, rubbing the posts with catnip or silver vine, feeding a few meals on the lowest platform, and playing a wand toy up the levels usually converts it within a week.

Wall-mounted and floor-to-ceiling options

Two variants solve real problems:

• Floor-to-ceiling trees brace between floor and ceiling under tension. They take almost no footprint and cannot tip, which makes them the strongest option for small flats — provided the ceiling is solid, not a suspended tile grid.
• Wall-mounted shelves and bridges free the floor entirely and can be arranged into a route around a room. They need studs or proper cavity fixings, and each shelf should be rated well above your cat's weight because landing force exceeds standing weight.

Both suit multi-cat homes, where the goal is more separate high spots rather than one tall tree that a dominant cat monopolises.
