I actually wrote a favorable post recently but I am running into problems with this climber!! Like some of the folk below I am finding it wobbly--I have one cat that will sleep in the hutch but mostly when the cats try to climb it is wobbles and scares them and also I just witnessed one cat try to take hold of the top shelf to get onto it and slipped off and fell because the cloth used to cover this one does not give them any grip. I have an older one of this manufacturer that the cloth is fine. also the other tree I have has a little edge around each high shelf for grip and safety this one is just flat and slippery. Disappointed!!!
