Hi

I was looking for cat trees/scratching posts for my two Maine Coons and Selkcah who breeds Norwegian Tree Forest cats recommended this:

Catrix Cat Activity Centre & Scratching Post

Its absolutely brillant - no screws, no bolts, modular and no unsafe bits. Look at the video on the site - you can expand it and you see 2 Maine Coons playing on it - which = stable! it comes with sisal and furry stuff posts. The guy who sells it is very, very approachable. They also have stands at cat shows.

I ordered via the web and got it delivered - absolutely no probs.
