Just because chins are nocturnal does not mean they should be in a dark room during the day. Follow the natural cycle of day light which would be the natural cycle a chin would have in the wild. They will have no problem sleeping and will be up playing in the evening. We use lighting that is energy efficient so it does not add any heat to the rescue. I have several nightlights throughout the rescue to represent moon light when it's time to say good night.
So after you get all the supplies and have the cage set up, you're ready for the big day! It's time to bring home your new chinchilla companion.
