I am thinking of switching over to only ASF's mainly because they have NO odor that I can smell. I got my first trio in march and havent changed the bedding yet. It doesnt appear soiled and still smells like fresh-cut wood shavings. Should I change it anyway??? I have probably changed my rat bedding about 3 times since then... How often do you guys completely clean the cages out for ASF's? Also, I know ASF's take longer to grow, but how long does it actually take to reach their adult size? A few months? More?
