My roommates cats loved it! Perfect height, I got this one specifically to fit the large 20lb cat on the top part (our king) and he fits just fine, the cats dont use the hammock below but LOVE the igloo section. My only qualms is I wish there was more room on the bottom for the cats to climb because every time they get on they seem a bit confused and reluctant to jump on because of the lack of room below, but they sure do ADORE the middle-Up~
