Hmm, why switch to "organic" kitty litter in the first place for these purposes? The nuclear waste is already toxic enough, I don;t think they need special organic litter to make it more, rather than less dangerous!

It's funny, Dad always kept a bucket of Speedy Dry (now apparently called Oil-Dri) in the garage for oil spills when working on cars or trucks, and I always thought that looked like kitty litter!
