I love mine too, although i have to admit there are some things that i'm not too happy with. The pans are plastic so if you have rats that like to chew...which most people do, you better hope they don't discover that the pans can be chewed through. I have this problem in one of my girls and I'm going to have to buy new pans at some point. Also the bar space is terrible for rats. I don't think its right to fatten rats up so they won't escape a cage...it poses alot of health risks. I had to spend alot of time modifying my cage so my girls could live in there...cuz even a full grown girl rat could escape.
Other than those two complaints, i love the cage though. its huge and the big doors are amazing. I guess there are pros and cons in all cages though and since it is designed to be a ferret cage, not a rat cage, i guess i can't really complain. I can't wait til the rat nation comes out!
