I am just a kitten so mommy won't let me go outside yet, so this tower is just what I need to see what's out there. I use the posts to scratch on and to climb so I don't need to use the furniture to sharpen my claws, yet. I use all the tower to play and sleep and mommy has put a ball chasing toy on the bottom so I can use every inch of my new play station. I am a happy kitty.
