Where to Place a Cat Scratcher to Protect Your Sofa

The thing we did not expect, and now hear about constantly: plenty of cats do not scratch a new sisal pad at all to begin with. They sleep on it.

It happened to me with the first one I put up, and I assumed I had bought the wrong thing. It is not the wrong thing. It turns out to be the point.

The advice you will read everywhere — put a scratcher next to the furniture your cat is ruining — is correct but incomplete. It treats a scratcher as a decoy. In practice the pads that get used are the ones a cat also wants to be on, and that changes where you put them.

Start with the corner they already chose

It is nearly always the same corner. Not the middle of the sofa, not the back cushions — the outside corner of the arm, at about the height of a cat standing on its back legs, worn to a pale fringe while the rest of the upholstery stays new.

Three things are usually true of that spot.

It is sturdy. Scratching is a full-body stretch — shoulders, spine, the long muscles down the back — and that needs something that will not move. A sofa arm is anchored by the weight of the whole sofa. A lightweight post that rocks under load fails on the first try, and cats do not give a wobbling surface a second chance.

It is visible. Scratching leaves a visual mark and a scent mark from glands in the paws. Both are signals, and a signal where nobody passes is wasted. So the chosen corner is nearly always on a route: beside a doorway, at the end of a hall, on the path between the food bowl and the window.

It has grain. Claws need something to catch and drag through. Woven upholstery has texture running the length of the arm, which is exactly why the marks always run the same direction.

From a cat's point of view, a sofa arm is an unusually good scratching surface that happens to also be furniture.

The rule: intercept, don't relocate

The mistake I made first, and the one I hear about most, is putting the new pad somewhere convenient for the human — the spare room, beside the litter box, tucked behind a chair. The cat carries on with the sofa, the pad is declared a failure, and it goes in a cupboard.

What works: put the new surface within about one cat-length of the damaged spot. You are not moving the behaviour to a better room. You are giving the same impulse, in the same place, on the same route, something better to land on.

Two metres away is not close. Beside the arm is close.

Sticking one to the sofa itself

Most sofas take a pad on the side panel without any trouble. There is a trick worth knowing that nobody tells you: you often do not need the adhesive at all.

The pad comes with a hook-and-loop fastener — the hook half (the scratchy one) and the loop half (the soft, fuzzy one). Peel the soft half away and throw it out. Woven upholstery is a loop surface. Press the hook half straight onto the side of the sofa and it grips, with nothing sticky touching the fabric, and it lifts off when you want to move it.

Two honest caveats.

• Corduroy will not hold. The ribs run one way and there is nothing for the hooks to bite. The same goes for tightly woven flat weaves, leather and most faux leathers. If you press the hook half against the fabric with your thumb and it slides rather than catches, that sofa is a no.
• Test somewhere hidden first. On loose or delicate weaves — linen especially — hooks can pull a thread. The back of the sofa, low down, tells you in ten seconds.

Then ask a second question: where does your cat like to be?

This is the part I got wrong at the start, and the part that has changed how we think about the product.

Watching our own cats and hearing from customers and friends, a pattern keeps coming up: a lot of cats like the smell of raw sisal. Not in a dramatic way — they do not react to it like catnip. They just choose to be near it. Some barely scratch the pad at all at first and simply sleep on it.

If that happens to you, nothing has gone wrong. The pad is doing the harder half of the job: it has become one of your cat's places. Scratching follows, because the first thing a cat does on waking is stretch, and a stretch that starts on a sisal surface tends to finish there.

So place it where the two answers overlap — where they scratch, and where they already choose to sit. If those are the same spot, that is your answer and you are done.

The play-mat use nobody plans for

Here is the one I did not see coming. A flat pad on the floor turned out to be the best place in the flat to play with a wand toy.

Play is when claws come all the way out. Mei is a laser-and-wand fanatic, and the damage in my old rental was not from calm afternoon scratching — it was from her landing hard against the wall and the edge of the sofa mid-chase. Once there was a sisal pad on the floor where the chase kept ending, that is what took the claws instead.

If you play with your cat in a rented flat, this matters more than the sofa does. A wall costs you a deposit. Choose the spot where the chase ends — usually a corner, or the foot of a wall she runs at — and put a pad there before you buy anything else.

Height is not a detail

Watch your cat stretch against something and note where the front paws land. That height — not a standard height — is where a wall-mounted pad goes.

Cats that stretch tall want the top edge at or just above their full reach; the stretch is the point, and stopping short of it is unsatisfying. Cats that scratch flat-out, braced on the back legs and pulling backward, want something on the floor and will ignore a wall.

Most homes have one of each. Watching for a day costs nothing and saves a wasted purchase. Our sisal pads mount on walls, doors, cabinets and tile, and lie flat on the floor — you do not have to guess correctly on the first day, which is mostly why we made them that way.

What to do about the sofa in the meantime

A new surface takes a couple of weeks to earn trust. While it does, make the old spot boring rather than punishing it — punishment teaches a cat to scratch when you are out of the room, which is worse for everyone.

Cover the worn corner with something that has no grain to catch: a smooth throw pulled tight, wide packing tape, a fitted arm cover. Take it off once the new pad is in regular use. The aim is a short dull period for the sofa, not a permanent piece of tape on your furniture.

Give it two weeks

Expect a day or two of sniffing and ignoring, then sitting, then — often quite suddenly — scratching.

If nothing at all has happened after two weeks, change the placement, not the product. Move it closer to the damaged spot, or turn it from vertical to horizontal. Those two adjustments account for nearly every "it didn't work" we hear about.

Renting, and worried about the wall rather than the sofa? This is the whole story of how we got here — including the deposit I did not get back. For the narrow technical question, see will an adhesive scratcher damage my wall. Still deciding between wall and floor? Start here.
