My girls love trees to scratch at. Any wood, really.

But a big ole piece of wood with bark is always a favorite.

If you want to completely stop scratching on certain surfaces - use plastic. Packing tape, plastic wrap, cling wrap, poly wrap, whatever. They hate plastic.

The back of a couple of my couches I’ve cut out poly(6mil) wrap to shape and they do not go near it. Same for the sides temporarily.

Door frames have clear packing tape smoothly covering the places they went for.
