I was down at the feed store the other day. I was kind of looking for something cheap to use as a cat litter that I might later run through the compost operation. I'm also looking for cheap bird seed for our backyard birds.
I came across a product called Dry Stall for horse stalls. The 50 lb sacks didn't mention exactly what it was composed of but described it as a volcanic rock aggregate.
The main purpose is to use in horse stalls to keep things from getting too muddy. The packaging then went on to explain that it could be added to hard clay soils to break it up and provide better water capacity. It also explained that it could be used as a cat litter and could even be mixed with clumping types of cat litter to make your clumping cat litter go farther.
Has anyone used this stuff for their soil or cat litter? I didn't get a price but maybe I can use some of this stuff.
I don't think it will harm compost but it doesn't break down. If it improves the soil structure then composting cat litter would be OK and we'd reduce our curb side trash pick up close to nil.
Thanks in advance
