Had this for a couple years now & my cat still adores it.He is very fussy & for first 6 months he didn't use it at all.Now it's used daily.He sits on top looking out the window, hides in the bottom with his toys & adores the top scratching post which has stopped him scratching elsewhere in the house.The top cover had to be removed, made the top too small and hard to access but he's happy without it & in warm weather will sleep on top without the cover.He's a very long cat & it works for him.
