Why Cats Scratch and How to Set Up a Scratching Spot
📝 Summary
Cats scratch to keep claws sharp (hunting, climbing, escape), leave scent to mark territory, and stretch the body — it's instinct, not a bad habit. Guide it: offer a horizontal and a vertical scratcher each ≥1.5x the cat's length, or DIY with sisal rope or cardboard. Skip plastic claw caps.
1 Why Cats Scratch
A common myth is that cats scratch because claws grow too long and annoy them — not really. In nature sharp claws matter for hunting, climbing trees, and escaping danger, so cats maintain them often to stay keen. Scratching also leaves scent from glands in the paw pads to mark territory, and it is a full-body stretch that loosens the muscles, which is why a cat just woken from a nap or let out of a crate heads straight for a post.
2 Building a Good Scratching Space
Have at least one horizontal and one vertical scratcher. The vertical post’s height and the horizontal one’s length should each be at least 1.5 times the cat’s body length so the whole stretch is satisfied. For DIY, sisal rope wrapped around a table or chair leg works well — that is the same rope on cat trees — and cardboard boxes make a decent alternative. Scratching is instinct, so the goal is to redirect and release it, not forbid it. Products like plastic claw caps fight the cat’s nature and are best skipped; living with a cat means accepting a little trouble along with the joy.
