Litter - time for a change...?

Here at CCC we think we're about to change the litter we use, it will still be wood based, as environmentally we feel this is more of a renewable resource, but perhaps it will have "clumping" capability. Chemical agents are added to make the clumping happen. It's entirely safe, even if kittens eat it, as of course they inevitably do, even if only for short durations in their kitten lives...
