Behaviour:
The chinchilla is a nocturnal animal, it sleeps all day and begins to come out at dusk. It is a social animal, so it is best to have several chinchillas. Be careful, two males together could fight. It is preferable to put together a male and one or more females.
Handling:
Don't grab your chinchilla by the scruff of the neck or the tip of the tail, as it can shed in patches. It is best to hold it with one hand at shoulder level and the second under the croup.
