Our cats are most happy with this condo, and so are the people, because it is sturdy, attractive and not so large as to be obtrusive in our living room.  I sprinkled a bit of catnip on the top and inside to get the cats to investigate it, and they decided right away it was a comfortable place to hang out.  Plus, excellent price and fast shipping from Wayfair!

Pros: Great value, good quality
