Jax Chinchilla Rescue
use critter care bedding. it elemates the smell all together. that way you don't smell anything and don't have the pans every couple days... just once a week
Critter Care is like Carefresh. Carefresh has been known to cause impactions in chinchillas who have eaten it. Some people still use it, but I would rather be safe than sorry. I only use pine or aspen shavings, or fleece. For smell I would recommend KD pine shavings changed out every few days.
