To answer Glow's cat poop question--
I googled "cat poop in compost/as fertilizer" and this is what I found:
A tremendously bad idea. Domestic animal feces contain a lot of organisms and parasites that can be harmful to humans -- think the bevy of worms that you vaccinate your dog/cats for alone. Specifically with cat feces, there's always a chance of Toxoplasmosis, which can cause birth defects in pregnant women. And this can be transferred if you put it on grass, use it in flower or vegetable gardens or consume the produce of said gardens.In fact, cat feces should be flushed, or disposed of in a tied up plastic bag, away from possible human contact. You really don't want it hanging around even in the litter box.
So now I am officially grossed out by both my flower garden and the cats' litter box.
ICK!
