Chinchillas should be kept in cages made of metal. Since they are extremely active animals, the larger the cage, the better.
A tall and wide cage is the best, but tall is better than wide if you can't get both.
A chinchilla can get its feet caught in wire floors, which can cause serious physical harm.
Chinchillas overheat easily, so it's ideal to keep them in a room that is between 60 °F (16 °C) and 70 °F (21 °C).
Do not allow them to be in high humidity, either. If you have a humid home, put them near a dehumidifier.
Your chinchilla should have a supply of good quality timothy hay available to them at all times.
Providing hay gives your chinchilla necessary fiber. Chewing hay helps them avoid tooth overgrowth.
If they are handled from birth, they will be tame and docile.
Chinchillas are usually very friendly but shouldn't be over-handled.
Chinchillas' teeth grow continuously and can grow up to 12 inches (30 cm) a year.
Also provide your chinchilla with branches that can be climbed and gnawed on.
