I cut and pasted this directly from their site: I use it and it works great, but you have to use it regularly, sometimes I forget.
I bought 40 lbs. it was $10.00 I don't really remember.

Chickens
Chickens have a lot of benefits, but they are by no means the neatest of barnyard animals. In fact their coops, hen houses and pens can get really stinky. Sweet PDZ is the answer to your smelly, dropping filled coops. Sprinkle Sweet PDZ liberally where the birds make their mess. Reapply regularly on the most frequently used roosting areas, and youll be well on your way to a healthy, safe and pleasant smelling chicken house. Sweet PDZ also makes it much easier to remove the droppings when cleaning out the chickens house. As an added benefit Granular Sweet PDZ can be safely eaten by the birds and used by them to grind their food. Clean smelling chickens = healthy chickens.
Sweet PDZ is a fantastic litter additive...
Use Sweet PDZ in combination with cat box litter for complete aroma protection. Unlike most litters that contain a masking scent or perfume, Sweet PDZ captures and eliminates ammonia and odors by neutralizing them through its unique mineral chemistry. For great litter box odor control, simply sprinkle 1/3 cup to a full cup of Sweet PDZ over the top of the litter. If you use a traditional clay (non-clumping) litter, you may also choose to sprinkle a covering of Sweet PDZ on the bottom of the litter box as this is where a lot of urine accumulates and odors develop. Additionally, because Sweet PDZ is unscented, it will not detour the cats from using their litter box.
