I have been having issues with my cage smelling and I am in the process of experimenting things that could work. It doesn't "stink" all it really is is the guinea pig marking their territory i guess but their cage is in my bedroom. A while ago I asked my mom if she had any ideas and she mentioned cat litter. But to put it under the fleece in a thin layer. Would that work if I got the right kind of litter or should I just do something else. Thanks
