My cat's love thier new Cat Tree.  It was easy to put together by myself (took about an hour) with my 8 year old tabby supervising.  She inspected each level as it went up and now has made the top level her own.  The two top shelves are a good size, perfect for naps and surveillance.  The tree has a small footprint and fits in my condo perfectly, but is large enough to provide both cats with plenty of room for play. The posts are wrapped in sisal rope and get lots of scratching instead of my couch! It is sturdy and yet still looks classy enough for my living room.  I definitly recommend this cat tree to anyone.
