Hello all. I am new to this website and new to owning my rats. We adopted 4 of them and we really do love them BUT.... they just smell so bad. Its not really them but the stink of there cage. I dont know what Im doing wrong. Can anyone please give me suggestions on this.... I have them in a two story ferret nation cage. They have hammocks and I have two big litter boxes with shaving in them because of the wire floor. I also do put some towels down not realizing when I got the cage that I couldnt put any bedding down and I worry about there little feet and bars. Currently they only have one shelf as I took the other one out cause they kept peeing on it and it just smelled. Im really frustrated and could use some help. Thank you
