Can I just say keeping your chinchillas in a glass vivarium could kill it.
Chinchillas do not cope with humidity and so a glass cage is a definite no no.
If your chin managed to drag a cable into her cage then it was simply because you left it too close to the cage for her to get at.
Anyone reading this please do not be tempted to by vivariums to house chinchillas.
How do you put shelves into a vivarium for her to use?
