For other Canadian members (I don't think you have Presidents' Choice brand stuff down in the States...), I recently discovered President's Choice 'Green' Cat Litter (http://www.presidentschoice.ca/en/pr...&CategoryId=41) - it's basically the same as WBCL - the texture of the litter is a bit different, softer, but it has all the same qualities - flushable, renewable resource, clumping, no silica, not dusty, made from corn - and is MUCH cheaper - a 7 lb. bag costs $6.99, compared with around $15 for the same sized bag of WBCL. It keeps the smell down really well, and the clumps don't stick to the side of the box. It can be bought in the grocery store, which is nice, too. Just thought I'd share, in case anyone else is looking for a cheaper alternative to WBCL (I thought the chicken feed idea was great, but unfortunately couldn't find a feed supply store anywhere near me!).
