I am going to have a rack of cages for my breeder rats. I have the rack located in my basment. Is it going to be too cold for the rats down there during the winter anyways? Maybe 50 or even maybe 40 degrees? My guinea pig used to live down there each winter but I think he was warm enough in his little house and all that fur, will the rats be okay? They will be in a tub that will have a lot of fluffy stuff on the floor so will that be okay? :confused: :rolleyes:
