It is a good cage, I bought the same one....BUT the chinchillas can get out of it because the bars are too big. You need to find a cage with small bars. Farret cages and Chin cages from the pet store would give you a better idea of how big the bars should be. You can use that cage and wrap chicken wire around it safely. The base of those is also not enough to hold in the chinny mess you will get! I did all of this with my baby thinking it would be ok, your best bet is to buy a chin cage or make one with bars small enough a chin wont get out.
