I thought it was bigger, I took the measuements , what myself and finance' agreed on that THE VERY TOP SHELF WAS TO SMALL AND BOTTOM WAS BIGGER THAN THE TOP, CATS Love the shelf to ly on, they like to be high up. I think if u exchanged the 2 pieces the shelfs in each other 's place WOULD MAKE IT ALOT BETTER, MY CAT IS 13LB. TOP SHELF ONLY NEEDED TO BE BIGGER,  --- she loves box opening and the height. I done 3 different mail cat orders and 2 were disappointing, their a local store were considering if we purhase another, but thank you.
