Made this cat scratching post for our kitties, although its dimensions might qualify it to be considered a cat pillar rather than a post. The cat scratching pillar measures over 7 feet tall and required 900 feet of sisal rope! The pillar leads up to a high perch above the fridge.
If I had a room designated as the ''cat's room'' I would do this, but not throughout my entire house. The cats have access to the entire house, but my entire house would not be dedicated as a ''cat house.''
