Hello. I'm a new rattie owner and I had a question about the free roam area. I have a carpeted floor in my room and I was wondering what to put on it, and if I need to? I have already taken a year before getting them to research about vets, cages, behavior, ect., But never found anything helpful about carpet. Also I'm getting my DCN cage on Monday for my two dumbos Salem and Raven!
