PetSmart sells Kaytee brand aspen, right?? I used to use that for the few snakes I keep on aspen until I started using LM brand aspen. If you think the Kaytee stuff is low on dust, you should try the LM. I know it's not as common, but in my experience it has WAY LESS dust than the LM. Also, it's cut a little different and yields itself better to tunnelling.
