Took her awhile to decide she would climb on it . I think it came with an unfamiliar smell , after I vacuumed it she stays on it all the time . At 16 pounds she doesn't trust the sitting circles so I took them off . Placed the top scratching post on top of the other post  , making one 3 post long scratcher . Since she is a long cat she likes stretching to claw . She hides stuff she is not suppose to have inside it , like pencils , water battle caps , and racquet balls  . The house looks small but she curls up inside no problem .
