DIY Scratching Post That Cats Actually Use

Cats do not scratch to sharpen claws. They scratch to shed claw sheaths, stretch the whole body, and leave scent from glands in their paws. Understanding that tells you exactly why most home-made posts fail: they are too short, too wobbly, and in the wrong place.

The three rules

1. Tall enough for a full stretch. Measure your cat stretched up a wall and add 10cm. For most cats that means at least 75cm, ideally closer to a metre.
2. Absolutely rigid. If it wobbles once, the cat will never trust it again. The base must be wide and heavy.
3. Where the cat already scratches. Not tucked behind a door. Next to the couch arm they have been shredding, or beside where they sleep, because scratching usually follows waking.

What to build it from

A 70x70mm timber post from a hardware shop, cut to length, screwed through a 40x40cm board of 18mm chipboard or pine. Screw up through the base into the post with three long screws so there is no movement at all. Add a second board on the bottom if it still tips.

Wrap the post in sisal rope — around 15 to 20 metres for a metre-high post, available at most hardware shops. Staple or tack the end at the bottom, wrap tightly with each turn pushed hard against the last, and secure the top. Sisal rope is far better than carpet, because carpet teaches the cat that carpet is for scratching.

Horizontal scratchers count too

Many cats prefer scratching horizontally. A flat corrugated cardboard pad in a shallow wooden tray, made from layers of cardboard cut into strips and packed tightly on edge, costs nothing and is often used more than a post. Sprinkle catnip between layers.

Getting them to use it

Rub catnip or silver vine on it. Play with a wand toy so the chase ends at the post. Reward with a treat the first few times they touch it. Meanwhile make the couch less appealing temporarily — double-sided tape or a piece of tin foil on the arm works, and can come off after a week or two.

Never punish scratching. It is a hardwired behaviour and stopping it entirely is not a realistic goal; redirecting it is.
