We got this playpen for our kitten at the time who is now 7 months she loves it, we have her food in it and her little box..we put two of the shelves
together on top yes you can't open one of the top doors because of it..no big deal ,our cats likes the wider shelve on top to sleep on and we have the other shelve over her food dishes so she can get up onto her top shelf ...she sleeps in there at night and enjoys it so much so when there are people over she will go into her cage and lay on the top , to be left alone..she will go into the cage by herself at night to go to sleep ..it does take two people to put this together if you want it done right..we did use the big Cable Ties to secure the sides of the cage better for extra safety for our loving pet..best buy we ever made for our kitten...and peace of mind when go out for the day..a must buy..!!!
