Before I got Frankie I bought a catbed and a scratchingpost. I tried to get him to used them, but he didn't like them. He was actually afraid of the bed, and he only used the scratchingpost as a stand for scratching higher on the wall.
I tried everything to make him scratch the post instead of the wall, even holding his paws and "scratch" it. I saw stupid youtube-videos about clickers and rewarding your cat. Nothing worked.
So I came over some catnip at the store. Not in a spray, but the actual herb. They said I should rub it on the things I want him to like. After I took a handful of catnip and smeared it on his stuff he went crazy. He started rubbing his face in the bed he was afraid of and cuddling with his scratchingpost, but also scratching it.
