I bought this to replace a stand that didn't have sleeping areas. One of my boys readily took to this cat stand. He sleeps on all the levels and because the middle shelf sticks out he can jump to the top level easily. He and his brother are 15 so not as much jumping in them. Rather lazy they are. I bought a self heating mat for the middle level and Rhett really likes that also. I did put a towel around the back of the bottom level to make it darker and cozier for sleeping.
