Chinchillas are very destructive .This means that cages that you can buy are normally made of metal.This is not my prefered choice as mine are always made of wood with wire fronts

The chinchilla cage should be the biggest you can afford and accomodate.The absolute minimum that i use for one or two chinchillas is 3 foot long by 20inchs wide and 20 inchs deep.

However big your cage is though, chinchillas should still be allowed free play time in one room on a daily basis. They should not be given the run of more than one room for several reasons:

1. They will gnaw anything within their reach. And there is not much which is out of their reach... Chinchillas jump high, fit into the tiniest spaces and are very fast and agile. You will need to chinchilla proof that room by encasing any free wires, filling or obstructing any gaps and by removing any dangerous objects they could hurt themselves on or eat. Chinchillas will eat anything they can. That includes carpet, wallpaper, even the walls themselves...! Unless you are able and you want to dedicate your whole place to chinchillas and turn it into some kind of giant cage, keep the chinchillas to one room only.
2. Even a very tame and well trained chinchilla can sometimes be very hard to catch. Getting hold of them when in one room is hard enough, you do not want to chase it around a whole house or flat!
The cage: make sure that your cage does not contain any wire shelves and floor. Serious accidents have happened when chinchillas got a foot caught in the wire (i.e.amputation of a leg, death)! Take wire shelves out or cover them with hardboard or wood. Bedding: most people use wood shavings. Make sure you do not use cedar as it is toxic! Pine is ok if nothing else is available. I personally use wood shaving that is dust extracted and treated. I find it works well and poses no dangers to my chinchillas

Furniture: Shelves should be wood. Untreated pine is fine (DIY bookshelves are great). They should have a nest box, no bedding is needed in it.I do put some hay into the nest box as i find they appear to feel more secure and they do eat it.

I also give my chinchillas toys to gnaw like pieces of wood, toilet paper roll, bark, twigs,and make perches out of large willow branchs with 4 inch plastic pipes hanging down from the top of the cage

The cages below can be split into two separate cages when needed.
