Jeremy (Who Dah?), Big Kitty, and overall picture. I'm 6 foot, the ledge he'll be able to get to is about 10 feet. I'm standing in front of the thing so the cat tree looks smaller.. See that folding chair in the background right past my leg? That is right next to it to give you perspective. Big Kitty doesn't look so bit in this shot either! Again you can see the ledge on the top where he'll be able to get to. Oh, and I'm not flipping you all off or anything.. I cut my finger doing something STUPID w/ the drill while mounting this thing.. So it has one of those plastic things on it w/ tape around it! I had to attach the cat house inside. The base of the tree BARELY fit in the door.. And I mean we pushed it through and there are blue/purple marks on my walls now.. heeh!:
