Getting new cage soon help

Ok, so I'm going to be getting a ferret nation cage soon hopefully. I'm confused on what to modify. Are you supposed to get fleece liners AND bass pans? If you get fleece liners do the chins pee on it? Or do you use a litter box? If I get bass pans what should I use. Carefresh? Cuz, when i'm cleaning my chins cage she seems to try to eat her carefresh.. she can't get to it in her cage though. So i'm worried she'll eat it if I use that. I can only use carefresh though because the other stuff makes us allergic. Since i'm in Canada it's really hard to get chinchilla fleece and stuff. Does anyone know where I can order in Canada for Fleece liners or Bass pans? I hope I make sense.. :) Thanks
