This cat tree goes perfectly with our living room décor.  My 7lb cat loves the upper perch and platform.  Both cats like the house, but don't seem interested in the tunnel feature.  I would not recommend this for large cats.  It is a tiny bit wobbly.  We solved this problem by placing it in a corner of the room.

Pros: Great value, easy assembly, cats love all the levels
Cons: Not for large cats, a little wobbly
