"We bought a cat tree from CozyCatFurniture.com and our two kittens love it. Here is it: http://www.cozycatfurniture.com/cat-trees/cat-climber-in-forest-style-with-tunnels-beds.html . It is fun to watch them attack each other from the different levels. It is sturdy and easy to assemble. The girls have had great fun with the leaves and I just keep tying them back on when needed. I plan on buying another tree soon and attaching them together for a bigger play area. This is definitely a good buy."
