Hi, Randi.

If Europe is anything like the US, you will have to make your own or buy from the internet. Big stretches over three feet (nearly a meter) toe to toe and most of the commercial, inexpensive stratchy posts in the stores only come up to his belly button!

The most popular material is not actually wood, but sisal, so you might consider that. Most kitties, for some reason, find it irresistable to scratch. You can easily make your own because sisal twine is pretty easy to find. Here is a good example you could use to make your own:



Also, it may not have to be a post, espcecially since he's already gotten in the habit of scratching a wall. You might could find a pad of sisal especially made to hang on a door knob and either train him to use it on the knob or mount it to a hidden wall. Here's an example:



If he insists on wood, though, I have actually heard of people going to a firewood dealer and buying an uncut log and nailing it to a flat board. The wood is untreated and would eventually detiorate and have to be replaced, of course. Here is a good commercial example:



Hope these help. Good luck with that big, bad boy!
