just my two cents.
I agree - when I used Aspen - I did a complete break down and cleaned/disinfected once a month at least. With fibrous beddings, it was impossible to get all the dirty bedding out with just spot cleaning.

Now I use newspaper and they get cleaned/disinfected once a week or more often if they defecate before then (and they do!)
