I adopted a 10yo kitty and needed a tree for him that isn't too high and provides 3 easy to access levels so he can jump up and down on them instead of directly to the floor.  Most trees seem to have levels that are almost directly under each other which would make it difficult for an older kitty to use. However this 10yo doesn't act his age, he's a bit of a spaz and zooms around including up and down this tree LOL  This is well made but I would prefer if all legs were sisal because the carpet gets torn up easily.
