How to Choose a Cat Tree Your Cat Will Actually Use

Katherine ReadOctober 6, 20269 min read

A cat tree earns its floor space when it’s tall enough to stretch on, steady enough not to rock, roomy enough to lie on, and parked where your cat already wants to be. Height on its own is never the whole specification, and most buying guides jump straight to named products instead of telling you that.

The criteria below come from veterinary and welfare bodies, plus two peer-reviewed papers on how cats use what we buy them. You won’t find a product named here or a price quoted. By the end you can size up any tower in any store, including the one your cat ignores.

Why Cats Want Height in the First Place

Elevation is a feline need rather than a luxury, and that’s where your shopping list starts. The AAFP and ISFM feline environmental needs guidelines list elevated areas alongside food, water and litter as key environmental resources. They describe a safe place as private, secure and “often in a raised location,” and they say access to an elevated area lets a cat monitor its environment.

Ohio State’s Indoor Pet Initiative says it plainer. A cat that sleeps somewhere high knows that no other animal or person can sneak up on it. The charity International Cat Care calls cats natural climbers that rest high because that’s where they feel safe.

So that’s what you’re buying: a perch, meaning any raised surface your cat can sit, sleep or look out from. The carpeted tubes underneath are only the delivery mechanism. There is more in our guide to keeping your cat happy and healthy.

Decide Where It Goes Before You Decide What to Buy

Placement decides whether the thing gets used, so pick your spot before you pick the model. Four locations have real support behind them. A tree that hits none of them will sit empty in a spare room while your cat sleeps on the radiator.

At a window. The AAFP/ISFM guidelines want at least one indoor resting area that gives the cat visibility of the outdoors. OSU gives you the reason: a cat that can hear and smell something it can’t see may be frightened by it.
Near where your cat sleeps. DePorter and Elzerman’s review places scratching options close to the cat’s sleeping areas. OSU explains the pull: cats scratch near where they nap so they can stretch after one.
On a route your cat walks. OSU recommends room entrances and the routes to food, water and the litter box. Cats use what they pass.
Beside whatever is being shredded. Cornell’s Feline Health Center tells you to put the acceptable surface next to the unacceptable one. You then move it gradually to where you want it.

Will Your Cat Actually Fit on the Perches?

A perch has to be wide enough and long enough for your cat to stretch out fully. That’s the AAFP/ISFM standard, and it’s a measurement you take off your own cat rather than off a product page.

Wait until your cat is flopped out asleep, measure nose to tail base, then hold that figure against the platform size in the listing. But a cat whose legs overhang the edge won’t settle there.

Perch shape matters as much as raw size does. The same guidelines describe a hammock-style dip in the middle of a perch as an aid to the cat’s sense of feeling hidden, so a padded, dished platform beats a flat board. International Cat Care is blunt about the consequence: beds too small for a cat to rest comfortably are less likely to get used.

No veterinary or welfare body publishes a perch size in inches, which is why you get a test here instead of a number.

The Stability Test You Can Run in 10 Seconds

Quick answer: Push the top level sideways with one hand. If it rocks, shifts or creaks, your cat has already made the decision for you. DePorter and Elzerman state that any scratching post should be sturdy and not waver if the cat exerts force on it. The ASPCA agrees that all cats want a post that won’t shift or collapse when used.

Cornell sets the same bar from the other side. Any post you buy or build should be sturdy enough that it doesn’t topple over during use. Stability is a behavior criterion as much as a safety one. That is because a tower that moves under load teaches your cat, in one landing, not to trust it.

Load the top level rather than the base, because the top is where your cat lands and where the twisting force is worst. Treat anything tall and top-heavy as a wall-anchoring job. No veterinary or welfare source names a height at which anchoring starts to matter, so err toward the bracket.

Sisal Rope or Carpet? What Cats Actually Use

Sisal rope is your better default, and survey data from thousands of cat owners sits behind that rather than a retailer’s product page. A survey by Wilson and colleagues collected answers from 4,331 cat owners across 39 countries. Carpet was the substrate owners offered most often, while rope was the one cats used most often when it was available. You and your cat are shopping for different things.

Surface	What the research says	Best for
Sisal rope	Used most often when offered, and OSU calls it tough enough for repeated use	Your default choice
Carpet	Offered most, used less, though cats aged 10 to 14 preferred it most often	Senior cats, carpet-scratchers

Your own cat’s preference overrides every rule above. Cornell tells you to match the surface to whatever your cat already scratches, so a committed carpet-scratcher may genuinely want carpet. The ASPCA notes that some cats prefer horizontal or slanted posts over vertical ones. One detail is worth carrying into the store with you: the published literature specifies sisal rope, not sisal fabric.

The Only Cat Tree Spec Published Research Backs

Exactly one real specification exists in the published literature, and you can hold any tower against it. DePorter and Elzerman’s 2019 review in the Journal of Feline Medicine and Surgery describes the ideal post as sisal rope over a vertical scratching surface, at least 3 feet tall. It should also carry two or more levels and a base between 1 and 3 feet wide.

Wilson’s survey points the same way. Cats scratched their preferred surface more often when the post was a simple upright, or a cat tree with two or more levels and at least 3 feet of height.

Read the limits of that spec carefully before you spend anything. It’s a scratching post spec rather than a rule about total tower height, and the base figure is a footprint rather than a stability rating. International Cat Care says scratching posts should be as tall as possible, so your cat can scratch vertically at full stretch. Cornell puts a functional floor under that: a post should be at least as tall as your cat standing on the hind legs with the front legs outstretched.

Two Cats Need Two Routes Up, Not One Big Tower

One tall cat tree in one corner is a single resource, however many levels it has. The rule from International Cat Care is one resource per cat plus one extra, positioned in different locations, and high resting places are on that list.

Count the cats, then add one. Three cats that aren’t one social group need four of every resource, so count your cats before you count the platforms.
Separate them. The AAFP/ISFM guidelines want at least as many single-cat safe places as there are cats in your home, in areas separated from each other.
Check the ways up. In a multi-cat household those guidelines want a safe place to have more than one entry, so one cat can’t easily block another’s access.

Bottlenecks turn a shared tree into a flashpoint, and a cat that senses a threat wants somewhere raised and private to retreat to. Wilson’s data cuts both ways for you. Unwanted scratching didn’t increase as households added cats, but it did decrease as the number of post types rose. So variety beats size.

Kittens, Senior Cats, and Sore Joints

Taller is not better for an older cat. For kittens and older cats with limited mobility, the AAFP/ISFM guidelines place boxes, perches and shelves at a relatively low height, or at levels reachable via ramps.

Three sourced adaptations cover it. Drop the overall height first. Then add a series of steps or a ramp, which is International Cat Care’s recommendation for cats with arthritis. Or stand furniture alongside the tree as a halfway platform, which is how the same charity suggests you make a high resting place easy to reach.

Then watch for the one signal that matters most to you. International Cat Care lists reluctance, hesitance or refusal to jump up or down among the signs of arthritis, which it calls very common in older cats. A cat that suddenly abandons a tree it used for years is telling you about its joints. Ask your vet before you shop for a replacement.

Cat Tree Specs Nobody Can Actually Back Up

Four numbers turn up on nearly every cat tree guide online. Not one of them traces back to a veterinary body, a welfare organization or a published paper, so you can ignore all four.

Spec you will see quoted	What the evidence actually supports
24 to 36 inches for small spaces, 48 to 72 for multi-cat homes	The only sourced figure is 3 feet of vertical scratching surface
Anchor anything over 60 inches to the wall	The principle holds, but the threshold appears only on retail pages
Platforms 18 to 20 inches wide for large breeds	The sourced standard is functional: long and wide enough for your cat to stretch on
A narrow base is safer	Wilson’s survey measured which bases were used more, not which were stable

A guide that can’t tell you where its numbers came from can’t tell you whether they apply to your cat.

What to Take Into the Store

Six checks decide it, and you can run every one of them on the showroom floor.

Measure your cat stretched out, then insist the perch is longer and wider.
Push the top level sideways and reject anything that rocks.
Count the routes up if more than one cat will use it.
Match the surface to whatever your cat already scratches.
Pick the window first, then find a tree that fits beside it.
Lower the height for a senior cat, or plan a ramp.

For more height in a room, our genius cat furniture hacks cover the DIY end.

Then watch what happens over your first two weeks. Where your cat settles tells you more than any spec sheet can. The top perch means the height was right, the enclosed box means it wanted shelter, and the windowsill two feet away means you picked the wrong corner. Use that for the next perch you add.

FAQs

How tall should a cat tree be?

At least 3 feet of vertical scratching surface, which is the one height figure published research supports. DePorter and Elzerman name it and Wilson’s survey backs it. Cornell adds a functional floor for you: the post should be at least as tall as your cat standing on the hind legs with the front legs outstretched. Beyond that, the inch bands quoted online trace back to retailers rather than to evidence.

Why won’t my cat use its cat tree?

Usually one of four reasons. The perch may be too small to lie on, or the tower rocks when your cat lands on it. The surface may be wrong for that cat, or the tree stands in a room your cat doesn’t use. So fix the cheapest one first, which is the room.

Is a cat tower the same thing as a cat tree?

Yes. Retailers use cat tree, cat tower and cat condo interchangeably, though condo usually signals an enclosed box level. None of the terms carries a standard specification, so judge the object in front of you rather than its label.

Will a cat tree stop my cat scratching the furniture?

A cat tree reduces furniture scratching rather than ending it. Wilson’s survey found unwanted scratching decreased as the number of post types in a home rose, so one tree is a start rather than a cure. A cat committed to your couch arm may need a second surface standing beside it.
