What I did on mine was get some rack shelfing from home depot and put heat tape on the bottom adjusted the bottom shelf so i
could fit 3 2ft tupper ware containers.The rack is 4ft long by2ft
wide by 2 section of 3 foot high and the cages fit perfect.You have no wasted space and only cost 49.97 for 2 set up instead of
a 100.00 plus for one(no offense jeff)you can kinda see them in the photo
