I thought this was kinda odd.... I found it on Thriftyfun.com Use Chicken Feed as Kitty Litter For an outstanding scoopable, clumping, odor controlling cat litter, try using chicken feed or chick starter crumbles. This is available at feed stores and farm and home stores. It costs about $10.00 for a forty pound bag. I kept my old clay scoopable cat litter jugs and pour it into them. One bag will fill five of the twenty pound litter jugs. We have 38 inside cats and we have cut our litter bill by two thirds. I feel that this does a better job of controlling odor than the clay scented litter. My only recommendation to ease litter box cleaning is a litter scoop called "Litter Lifter" you can find them on a Google search. This scoop is great with any litter, no more shaking the scoop, the clean litter just falls through the scoop.
