Well, my constipation still returns occasionally. This may be one of those basic questions that I should have answered for myself already, but: what causes the compacted feces that sink to the bottom of the floor? Here are the things I remember reading and suspect cause it:

- lack of water (I do live in a desert, but I have to be careful about adding stuff to the water, or I'll get the clear urine like it's coming straight back out)
- lack of active intestinal flora in active forms (and why isn't it "intestinal fauna," anyway?) - I thought part of what makes feces fluffy is proper bacterial action
