litter

Please don't ask how, but I recently ran across a site which reviewed natural cat litters. I read the review, and decided I would try the 'world's best cat litter' (with a name like that, why wouldn't I?). If I had looked at their website, it probably would have struck me before this evening, when I was putting it into the litter box, but the litter is made from corn. This strikes me as a seemingly bad plan - I'm pretty sure corn is supposed to be eaten, not put in your toilet (or burned as heating fuel, either). In general there's a lot of anecdotal evidence (or rumour) that regular kitty litter is bad (special bonus - note how easily the author decides that strip mining is actually a warm fuzzy thing done by unicorns). But as with all things internet-y, finding authoritative information seems to be tough.
