Oh man, that is funny.... At the risk of taking this whole thing way too seriously, and I will try to refrain from shit related humor for now... The way the feces of a carnivore/omnivore breaks down can be tricky. Nearly every book I've read on the matter has warned against using it. I know there are forms of composting which rely on anaerobic activity (without oxygen dependent microbes) and for that, one could use human feces, but for aerobic composting I would worry that it may do more harm than good.... It would eventually break down, like everything else, but it could complicate the process and take way longer (so many chemicals in our shit, and nasty, anaerobic bacteria). If you really want to try it, age it well and keep it well aerated for many months before you add it to the 'real' compost pile, or get a Bokashi bucket, which will break down stuff you should NEVER put in 'normal' compost piles.. Compost is cheap and easy to make with a little space and time. A simple 50/50 mixture of green plant clippings (rich in nitrogen), and brown oxidized materials (dead leaves, newspaper- rich in carbon), is all that's needed to make some decent compost. If you want a better product, a bag of cow manure is dirt cheap... and to sweeten the deal add your non-meat kitchen scraps (no dairy, citrus or shell-fish), watered down molasses, kelp (powdered or liquid is fine), egg-shells (to add calcium and bring up the ph) and you have yourself a lovely compost formula. Pile it high. I like to use some light materials, like coco or turface to let air in... A 3x3x3 area is supposed to be ideal, as it helps the center of the pile reach a high enough temperature for fast breakdown without literally baking the microbes doing the job. A big enough pile of composting material can literally combust under the right conditions! Mix all your ingredients together often to get oxygen into the center and keep the carbon/nitrogen ratio at 30:1. The center is where most of the activity is taking place... you have to get everything into the center to heat it up, break it down, so turn often and thoroughly. After about 6 months to a year (can be shorter with the right conditions) you'll have a compost rich in humic acid, amino-acids, beneficial microbes and all the macro and micro-nutrients (though maybe not in perfect proportion, they will break down slowly, so no worries about burning). Never use it in higher concentrations than 30-40% or you may smother your roots, causing root rot. I use a lot of perlite and turface to open it up and let it 'breathe'.
Shit. There, got it out of my system.. pun intended..
