Aquariums should never be used because the chinchilla can easily over heat in them. I prefer wooden shelves because they give the chinchillas a great chew toy. Wire shelves can be used as long as they are the same size wire as the floor. Pine shavings can be used to line the cage or pan. Care should be taken when choosing where to place the cage.
Chinchillas have such thick fur that overheating is a danger.
They must also stay out of drafts. Also, because they are awake at night, your bedroom may not be the best area. Accessories Chinchillas need a glass water bottle. Plastic can be used, but if the chinchilla can reach it, he will most likely chew a hole in it. Food bowls are best hooked to the side of the cage.
