I'm at a loss....

Came home tonight after work to find one of my chinchillas dead. I'm at a loss of what I did wrong. She lived in the same cage as her mother and her mother looks fine.



Should I clean the cage to clean the smell of her?



What can I do for the mother?



I've been apologizing everytime I see her.



I'm so sorry Roo.



I'm so sorry Boo.
