Here is Bob on the first cat tree that I built for him. This is one long cat, the platform that he is lying on is about 28” and if he stretches out he will hang off either end. I made this one because I couldn’t find a scratching post that was long enough for him if he was completely stretched out. By the way that is about 38”, yes I measured it once. I wanted to be sure that he had a proper scratching post, didn’t I?
