It took my two cats about a week to really get used to it. Maybe it was the smell... Even though this is one of the only brands/models that says it doesn't use manufactured wood with formaldehyde in it (which was really important to me to keep my indoor air quality clean), there was some strong off-gassing for at least a week. But, besides that, it was easy to assemble, is very sturdy, the pedestal platform bed is big enough (most of the other brands have pedestal platform beds that are way too small for an average-sized cat), and the color is nice. The little house is way too small for any real use (maybe best for a tiny cat), but it's not a deal-breaker. The cup-shaped bed is weird, but fun. No one's used the hammock yet, so we'll see. All in all, it's a decent design. My two main reasons for buying it were the no formaldehyde and the large 15 inch size of the bed.
