This is definitely the "Rolls Royce" of cages.I received it , had it put together , and went online to purchase "another one"! I have them on one wall in my office , boys in one , girls in the other ! I rescue...I do not breed. Everything is good , it's a great product. With "one"exception...the small animal community is crying for 4" deep pans on the full levels. It would only benefit this manufacturer to hear them .
