I LOOKED AT SEVERAL CAT TOWERS.  LET ME TELL YOU THAT THEY ARE EXPENSIVE!  MOST OF THEM  WITH CUBBIES ARE NOT FULLY ENCLOSED,   THIS IS THE MAIN REASON I PURCHASED THIS ONE.  IT IS SPACIOUS ENOUGH FOR OUR LARGE CAT ALSO.  THE ONLY DOWNSIDE IS THE CARPET IS THIN BUT I GAVE THIS PRODUCT 5 STARS BECAUSE THE PRICE IS RIGHT FOR WHAT YOU ARE GETTING.  OVERALL IT IS A GOOD PRODUCT THAT I WOULD RECOMMEND.
