Why Is My Indoor Cat Scratching Everything?

Cats scratch to shed nail sheaths, stretch the whole body, and leave visual and scent marks. You cannot stop it, and should not try — the goal is to make your preferred surface the obvious choice.

Why cats scratch

  • Nail care — removing the outer sheath
  • Stretching the shoulders, back and toes
  • Marking territory visually and with scent from paw glands
  • Releasing tension after conflict, excitement or a surprise

Why your sofa wins

Sofas are tall, stable, textured and in the middle of the household's social space — exactly the specification of a good scratching site. Posts fail when they are short, wobbly or hidden in a spare room.

Choosing a post the cat will use

FeatureWhat to look for
HeightTaller than the cat's full stretch
StabilityHeavy base; no wobble under full weight
MaterialSisal rope or sisal fabric; some cats prefer cardboard
OrientationOffer both vertical and horizontal options
PlacementNext to the furniture being scratched, then move slowly

Redirecting the habit

  1. Put the new post directly beside the damaged spot.
  2. Make the furniture less appealing temporarily — a cover or double-sided tape.
  3. Reward the cat when it uses the post; never punish scratching.
  4. Keep nails trimmed to reduce damage in the meantime.
  5. Once the post is used consistently, move it a few centimetres a day if needed.

Declawing is not an option

Declawing removes bone, not just claw, and is banned or considered unethical in many countries. Environmental changes and nail trimming address the problem without harming the cat.

Frequently asked questions

Will trimming nails stop scratching?
It reduces damage but not the behaviour, because scratching also serves stretching and marking needs. Trim nails and provide good posts together.
How many scratching posts does one cat need?
At least two in different rooms, ideally with different orientations and surfaces. In multi-cat homes, more.
Does catnip help train a cat to a post?
It can. Rubbing catnip or a silvervine product on a new post encourages first contact; the reward for using it does the rest.
