Thanks yall for all your answers, and your own routines. I'm going to keep trying the spot cleaning for now and keep an eye out (and I guess nose too) for when he needs a complete change.

Right now I'm using aspen shavings, but when I'm finished with this bag I want try the carefresh. I used that for my pet rabbit and liked for him. I forgot that it said it can be used on such a wide variety of animals.
