BOUGHT THIS CAT TREE TO REPLACE SMALLER ONE. IF YOUR CAT IS A "TREE DWELLER" THIS IS THE ONE. MY OLD CAT TREE WAS 52"AND THE HEIGHT WAS ADAQUATE BUT IN MY CATS WORLD THE HIGHER THE BETTER. SHE LOVES THE UPPER LEVEL AND THE SECOND LEVEL IS GREAT FOR LOOKING OUT THE STANDARD BACK STORM DOOR. I BOUGHT THIS ONE ALSO BECAUSE OF THE "BIGGER HOUSE" AND THE HIGHER LEVEL THAT IT SITS. SHE NEVER WENT IN HER "OLD HOUSE: BUT LOVES THIS ONE WITH THE 2 ENTRANCES AND HIGHER OPENINGS. I PUT HER TOYS IN THERE AND SHE LOVES TO "PUSH" THEM OUT TO MAKE ROOM FOR HER. BEST CAT TREE FOR THE PRICE--
