Cats love it. Only flaw is there is only one platform to jump down onto from the very top. I bring this up because one of my cats got cornered when another wanted her top spot and she was not directly over the round platform where she could easily jump on to escape. Other than that it is perfect. My older cat never used the other cat tree we had but as soon as I’d assembled this tree, he jumped up to first platform and made it his spot.
Update 12122  my cats no longer use this tree. One of my cats had an accident trying to launch onto it and hit herself into the small round platform. They won’t even use it as a scratching post. Not sure what happened but it is very disappointing. Perhaps it’s too narrow I am donating it to our humane society here on the island.
