What type of litter do you use?

I don't know about you guys, but we love our litter DUSTY, even though our Mom doesn't buy that kind anymore (hrmph!)...but if we could design our own litter, it would be this (thanks to Zoolatry for the creative contest idea!) Our Mom said just last night that Marley needed to visit Tut's tomb because his bum was stinky!
