I love this beautiful cat tree and it's now in our family room where we lounge around and watch TV. My husband and my friend, Joy, jumped right in assembling this huge cat condo despite the poor directions. I was their step and fetch it assistant, so the three of us had it assembled in about 3-4 hours after Mark laid out all the parts to make assembly easier and faster. I have a cattery so I introduced my cats one at a time to this awesome cat tree and they loved it. The ladder was broken underneath the faux fur but Mark and Joy made it work. I added more dangling toys which they love. I would suggest three people assemble this big thing to make it go faster and with less frustration. I don't think cats over 10 lbs would have much wiggle room maneuvering up and down this cool cat tree.
