For Older Cats
Wobble-Free
The tree itself is nice once it is done but it took me over 1.5 hours to build by myself. The box is incredibly heavy at 45.8 lbs and was hard to move upstairs. I wish the instructions were a little clearer because there are 18 different posts to keep track of during the build process. Cats like it but be prepared for a project.
