Cat Tree seems to be enjoyed by my cats and is fitting its purpose to give them a space in the house. The only catch that we seem to have is the mini ramps going into the cubes, they seem to not be as stable and little short but the cats don't seem to mind to much as they are jumping into the landings and cubes. This could be the reason why they don't use them. It was fairly easy to put together, I have added twine to the legs to prolong the use of the bottom legs.
