Bought this for our 8yr old cat who didn't have enough high spots to sit on. She was straight onto it when built (which didn't take long and had easy instructions to follow) which surprised us knowing how fussy she can be.  We put it beside the stairs and she now runs round in circles having great fun. Plenty of shelves to sit on and definitely a big hit. Having bought other toys  beds etc in past and seen them ignored,  I'm really happy with this purchase. Its extends or shortens at top to fit any room height and is really sturdy.  And she's found her favourite bed already lol. Perfect cat tree. ⭐⭐⭐⭐⭐
