The Wilton Mall no longer has a pet store, Benson's does not carry Chinchillas that I'm aware. There is a Pet Smart in the Target plaza right next to the mall, but for a Chinchilla you may have to take a trip to the Albany area.
Pet smart in target plaza
Pet smart not far from the mall or benson is close too
I know there is not a pet store in Wilton mall anymore.
you should ask the pet store directly, google probably no idea.
