Query: solid scratch post

I have a big Maine coon who was scratching my rented apartment's door frames, so I ordered this scratch post after reading other reviews. I used a cat dancer to get him to jump and climb on it and he was instantly in love with it! No more scratching at door frames. It's really easy to put together, just 2 screws in the base, and is solid enough for my big cat to run and jump on it and climb all over. It is HUGE, make sure you check out the measurements.
