Not Good for a "Fat Cat".  My cat loves the scratching pad and does not walk past it without scratching.  He wants to get up on the tree, and he still climbs on his old cat tree, but he just doesn't fit on the tiny little platforms of the new tree.  We took two of the platforms off to make more room and put cat treats on the remaining ones to entice him.  He got up on them and I wish more than anything I had my phone on me to take a picture.  His XL Body hung off the platform.  Good looking tree, easy to put together and if you have a skinny cat could work great.
