More on poop

Living in California near the bay, I'm particularly concerned about what goes down the drain.  I think one of the greatest assets that California has is its spectacular coast line!  Recently, sea otter deaths have been linked to toxoplasmosis parasites found in cat feces that is either flushed into the toilet, or gets into the bay through runoff.  And although its not conclusive, its the likeliest source.  Last summer when I visited the Monterey Bay Aquarium, I started thinking about how I could reduce my cats' impact on the environment.  I wanted to do something about their litter waste.  We switched from a clay litter to a compostable litter, and started throwing away the litter in biodegradable bags.  But ultimately, I wanted to make sure that their poop didn't make it into the bay at all.  The easy way of doing this, was ensuring that the cats' poop never left my charge.  So last weekend I built an underground digester.

Essentially, its just a hole in the ground, with a plastic lid over it, so that I can keep animals (like the cats) out.  I drop their used litter into the hole, add some septic tank enzymes into the hole, a bit of water, and voila!  The litter gets broken down, liquefied, and fertilizes the soil around it.  I'm still waiting for the first bag to break down, that I put in there.  Supposedly it should only take a few days.  Its been in there for now 2 days and I'm getting impatient.  If this works well, then maybe I'll start collecting my own waste and dropping it down the hole.  ;)  Or maybe not....  Some things really are too gross for me too.
