I purchased this because my cats like to club high cat posts. It fits secure floor to ceiling. They like to scratch the sisal rope. The reason for 3 stars is because the shelves are an odd shape so my cats can’t climb over each shelf to get to the next level. The only shelves they like are the wedge shelf and the little round bed shelf. I ended up taking all the square shelves off completely and putting the round bed at the top and then the wedge shelf below that one so they climb up the post to the wedge shelf. The picture shows the cat post before I removed the square shelves. Also the round bed shelf fits my 8 pound cats but any larger won’t fit.
