Catland, wecome to pet talk!
It has been generally observed that any wood structure will suffice for a scratching post. I have a home-made "A-frame" easel. My furkids are constantly scratching and climbing it. They really like to dig their claws into something that is soft, such as redwood, or cedar. White pine will do, just as long as it is soft wood. Also, that they like to stretch their bodies when digging their claws into the wood. Nearly anything will do for a scratching post. Just a log nailed to a flat piece of wood will make a fine post for them, especially if it pine with the bark still on it.The post length should exceed the length of the cat so, they can stretch out.
