Are you concerned with the glue on the toilet paper rolls?
If so you can buy the cardboard rolls that people ship posters in or that carpet comes rolled on. Those don't contain any glue.
If you are concerned about them eating the paper, there is nothing wrong with that, its just like human children eating paper, it does digest.
You can buy or making hanging toys for your chin, and clip them on at different levels (i.e. from the ceiling, from the side near to ceiling and from the side a little lower) all around the cage.
Also one thing i've found that chins like are shiny objects. Buy some florists wire from michaels, and go to home depot and buy some washers and nuts and also some keyrings and you can wrap the wire around them to make hanging toys out of those as well. I wrap the wire around each object (and sometimes two) every 2 inches or so. I placed this in a cage with a fur chewer and hes been so busy playing with that and his wooden toys he has stopped.
You can also place the chiller on her floor, you may have to wash it once in a while but atleast she'll have it.
If you have metal (wire) shelves you can use on of those really big binder clips to clip it to the shelf.
