Cage arrived missing parts and bent. Apparently someone else tried for an hour to put it together only to realize it isn't possible with the missing ladder and attachment piece needed to connect the exercise wheel. Cage should come with two ladders, one bent to attach the first platform and a straight ladder to attach the first platform to the second one. The product we received appeared to be a return and was missing the straight ladder plus the piece needed to attach wheel. Save your money-don't buy yourself aggravation!
