My cats are mostly pooping outside in secret places (like the veggie gardens, I imagine), except for winters and whimsy, but it's enough it suddenly dawns on me that I are being a dope by not thinking about this.
So, three thoughts in my dopey little head: gypsum, calcined clay (brand Turface is an amendment I like to use), and wood ash.
Calcined clay/Turface is used to keep ballfield surfaces from getting soggy; in the garden, it absorbs water, making it available to roots when soil dries out b/n rains. Thought it might be a good litter substitute. Gypsum also seems an obvious choice;some people think you can't use enough of it in the garden (though others say it's benefit is too temporary to be worth the investment). Both products are purchased in garden-sized bags and significantly cheaper than commercial cat litter. If I replaced my kitty litter with gypsum and/or calcined clay, and designated a felinure compost pile and aged it a couple years...why not? Calcined clay doesn't degrade (Turface is tested at lasting 100 years ie permanent), so perhaps it would be too much Turface-to-compost ratio. Plus, I would probably need more of, er, the other kind of browns. I would have to play with it--I mean, experiment.
Can I double-duty my deep thoughts about doodie into a use for my wood ash? I read on a site I can't find now about using wood ash to anaerobically compost human waste--alkalinity of ash combining with acidity of kaka in the anaerobic environment is supposed to disable pathogens, as I recall. Whether or not that's true, if it were a viable base for the felinure compost pile, that would be great. (I would really like to find an easy way to use my ashes.) I wonder if I could just dump them in a feline compost spot, and just keep adding kitty box contents to it until some balance of materials is achieved, and then let it set for a year or two.
Here is a site that suggests making an anaerobic compost, by burying a garbage can or bigger container 6-12" deep, with bottom cut out and replaced with mesh to protect from varmints but allow worms. (Though varmints probably don't go for kitty crap, and more power to them if they do?) It talks about only using small amounts of wood ash. But with enough carnivorous kackie in it, perhaps it would be a good marriage?
Any thoughts welcome on composting kitty kaka, and also super-easy uses of a large yearly quantity of wood ash (already know dinky or high maintenance options like lye and baking soda, and sprinkling it here and there).
