Here is my current tree. See the corners and bottom are totally scratched away, and making a mess. I thought the cats would like to scratch on the real wood tree parts, but they never do. They like to sleep in the top perch and the kitty cup, but hardly ever go in the box with the hole. Hanna will sleep in the tube, but the other two cats never do. My other cat tree is a 4 level rectangle box with holes, and it really isn't that stable. Hanna uses that one, but the otehr two cats are wary - they never go on it.
