Quick answer: To protect sofa corners from cats overnight, fold a heavy spare curtain or drape over the corner and tuck it in so there is no loose fabric to grab, lift window curtains clear of the floor with tie-backs, and set a sturdy scratch surface right beside the corner. In the morning, fold the drape away and leave the scratcher in place.
Many cats do their most enthusiastic scratching at night or very early in the morning, when the house is quiet and they wake up ready to stretch. If the sofa sits near a window, the target is often the sofa corner and the floor-length curtains beside it.
You may not want covers on the sofa all day, especially when guests visit. This setup uses a spare curtain panel and a few tie-backs to protect both the corner and the curtains overnight, takes two minutes to put on and off, and works best when paired with a scratch surface the cat prefers.
Why Cats Scratch Corners at Night
Scratching is normal behaviour: cats scratch to stretch, keep claws in shape and leave scent marks. The ASPCA's guidance on destructive scratching explains that cats often scratch after waking, which for many cats is during the night. Corners are prominent, sturdy and on the cat's route around the room. Our explainer on why cats scratch corners covers the territory side in more detail.
Kittens and young adults tend to scratch the most, while older cats often scratch less but still want a morning stretch, so the same setup suits most ages with small tweaks.
What You Need to Protect Sofa Corners From Cats Overnight
- One heavy spare curtain panel or a thick canvas drape
- Two or three curtain tie-backs or soft fabric ties
- A few upholstery twist pins or large safety pins
- A sturdy scratch surface to place beside the corner
- A basket or drawer to store the drape during the day
Choose a tightly woven drape. Blackout curtains, canvas and heavy cotton work well; sheer or loosely woven fabric gives claws something to catch.
A spare curtain from a charity shop works fine as long as the weave is tight; check that it has no loose threads before use.
Step 1: Drape the Sofa Corner
Fold the spare curtain lengthwise so it is double thickness, then drape it over the sofa arm and down the outside corner to the floor. Tuck the top edge into the gap between the cushion and the arm so it cannot be pulled off. Fix the lower edge with two twist pins into the base fabric. There should be no loose flaps for the cat to grab or swing on.
Step 2: Lift the Window Curtains Clear
Floor-length curtains next to a sofa corner are an easy climb. Before bed, gather each curtain with a tie-back at about hip height so the bottom hangs well above the floor, or loop the bottom hem up over the tie-back. Our guide on how to stop cats scratching curtains has more permanent fixes, and our deterrents that don't ruin decor guide covers curtain protection in more depth.
Step 3: Give the Cat a Better Target
Covering the corner alone often moves the scratching somewhere else. Place a sturdy, tall scratch surface right next to the covered corner so the cat has an obvious alternative. Cats Protection's advice on scratching recommends sturdy posts tall enough for a full stretch, placed where the cat already scratches. A side table with a sisal face, such as the CozeCat Side Table, can stay beside the corner during the day too.
Step 4: The Morning Routine
In the morning, unpin the drape, fold it and put it in a basket or drawer. Release the curtain tie-backs. The scratch surface stays where it is. The whole routine takes about a minute, so the room looks normal for the day.
- Unpin and fold the drape
- Store it in a basket by the sofa
- Release the curtain tie-backs
- Check the corner for any new marks
- Reward the cat if it used the scratcher overnight
Adapting the Setup to Your Sofa
Square-armed sofas are the easiest to drape: the fabric sits flat and tucks in cleanly. Rolled arms need a longer drape and a twist pin on the inside of the roll so the fabric follows the curve. Leather and faux leather can be slippery; put a thin rubber rug grip under the drape so it stays put without pins. On a sectional, focus on the outside corners the cat can reach from the floor, not the inside angle. Our corner scratcher table for rolled-arm and armless sofas guide shows how corner shapes change the setup.
Making Night Scratching Less Likely
A short play session before bed tires the cat out and makes night scratching less likely. Feed a small meal after play, which many cats follow with grooming and sleep. Our overnight sofa arm scratcher setup covers a similar routine for arms rather than corners.
Training the Cat to Prefer the Scratcher
The drape works best as a short-term tool while you teach the cat to use the scratch surface. Rub a little catnip or silvervine on the scratcher if your cat responds, drag a wand toy across it to invite a scratch, and reward with a treat the moment the cat uses it. Do this every evening for a week or two. Our train your cat to use a scratcher in 7 days guide gives a day-by-day plan, and most cats can manage without the drape once the scratcher becomes their habit.
Watch the corner each morning. Fewer marks on the drape means the plan is working.
Keeping the Drape Clean
A drape picks up hair and scent over time. Shake it outside every few days and wash it every couple of weeks on a normal cycle with unscented detergent. Keep a second drape so one is always ready. Avoid strong-smelling fabric conditioners, which can make the cat more interested in scratching or sniffing the fabric.
Why Not Just Use Tape or Spray?
Double-sided tape works for some cats but leaves residue on some fabrics and must be replaced. Scented deterrent sprays can stain and some cats ignore them. A drape is reusable, leaves nothing behind and can be washed. PetMD's guide to stopping cats scratching furniture suggests combining a physical barrier with a better scratch option, which is exactly what this setup does. Our furniture protector tape pros and cons guide compares tape in detail.
When Overnight Protection Becomes Permanent
If you find yourself draping the corner every night for months, a permanent solution may be simpler. A scratcher table that sits flush against the sofa corner protects it all day and night, and looks like furniture rather than a cover.
Sizes and left, right or pair options are shown on the CozeCat Side Table page.
A Corner Scratcher That Stays Up All Day Single tables start from $199.99 and a Pair from $389.99. Orders go out with Next-day shipping, and unused tables can be returned within 30 days, with return shipping paid by the buyer unless the table arrived damaged or defective.
Where the Drape Setup Goes Wrong
- Using a thin or loose-weave fabric the cat can grab
- Leaving long flaps that turn the drape into a toy
- Covering the corner without offering a scratch surface
- Forgetting the curtains beside the sofa
- Shouting at the cat when it scratches at night

Overnight Sofa Corner and Curtain Protection: FAQs
Will a curtain over the sofa corner stop my cat scratching?
It stops claws reaching the upholstery, but on its own it may simply move the scratching elsewhere. Pair it with a sturdy scratch surface right next to the corner. Most cats use the scratcher once the corner is less appealing, especially if you reward them when they do.
What fabric works best as an overnight drape?
A heavy, tightly woven fabric such as a blackout curtain, canvas or thick cotton. Fold it double and tuck it in firmly. Avoid sheer, knitted or loosely woven fabrics, which give claws something to catch and can turn the drape into a climbing toy.
How do I stop my cat climbing the curtains at night?
Before bed, gather floor-length curtains with tie-backs at about hip height so they hang clear of the floor. Give the cat a tall scratch surface and a high perch nearby to satisfy the urge to climb. In the morning, release the tie-backs so the room looks normal.
What makes a cat attack the sofa corner after dark?
Many cats scratch when they wake, and they often wake during the night or early morning. Scratching stretches muscles and marks territory. A play session and small meal before bed help, as does placing a scratch surface at the spot the cat already uses at night.
