Congrats about your new chinchilla. That cage is fine for now, but I would suggest getting a cage with multiple levels and more space because chinchillas are very active and love to climb and jump. A multiple level cage with more room would be the ideal thing, but for the time being that cage would work. If you do use that cage, you might want to give your chinchilla lots of time to run around in an open space so they still get plenty of exercise.
I hoped this helped! Any questions about chinchillas just ask
