It took a while for me to get my cat to use it. It like it and it was easy to put together. The very top level is a little wobbly, not much but my cat doesn't trust it enough to visit that level. He doesn't care for the enclosed area too much but will go there if I place snacks in there. It seems as though there is enough room for him to turn around, but maybe he would like a little more, not sure.
