I have not posted in forever...sorry. I went back to work full time in April and with the Rattery and a 2 year old it has been kind of hectic. The boys are doing great, as well as the girls. I eneded up switching the boys to a large Martin's cage...I had the double unit critter nation for my boys since Feb and although it is a beautiful cage. I was frustrated with it for several reasons. First the pans were too shallow for bedding so I had to use fleece, which the boys peed all over and then destroyed. So I was having to change the fleece like every 2 days at least and always running out of it. Also b/c of the shallow pans they would throw out a ton of poops/food stuff all the time. I was constantly having to vacuum around their cage (to keep my 2 year old from playing in or eating it :0) Lastly and the real kicker for me, living in a top floor apt, I was not able to take it outside to hose down and it was way too big and heavy to get in the shower. So even with wiping it down I could never get it clean enough (since pee would get in the grooves)
Overall it really is a nice cage and If I did not have so many rats to clean up after, maybe the fleece and poops on the floor would not bother me as much. But I think you would definitely need a way to hose it down good regularly. Most people that have a CN love them, so maybe I am too picky :) or maybe my boys are complete slobs :)either way the Martin's works better for us.
I ended up selling it to Carolina Rescue really cheap to help them out. Rather than save it and maybe not use it for awhile.
