Chinchillas are animals that have to be careful with water, let’s see exactly why. Chinchillas have fur that is incredibly thick and this thick fur if it were to get wet cant dry on its own. If it gets wet then their skin will grow mold and that can make them sick. So you can’t give them a water bowl in their chinchilla cage. That will just really put them in a bad position.
You need to get a bigger water bottle, like the one that you would give to your hamster. This way they only get water when they drink and they fall or spill it all over. You might be wondering about moisture since that is still a little problem. They do have maintenance that helps to keep them dry and that is why they take those fun looking dust baths.
