What's the green way to dispose of dog doo-doo and cat poop? Slate's Green Lantern column has good answers...
Both dog and cat poop can contain dangerous bacteria and other parasites, so it's something that you want to handle with care and keep out of the storm drain. The Lantern suggests using biodegradable waste bags to pick up and transport waste. If you have a dog, you can compost the poop, but it is a good idea to keep the dog waste compost separate from other compost. If you don't want to compost, you can also bury dog waste under at least a foot of soil.
For cat owners, you'll want to stick with the litter box, which is good news if your cat is as stubborn as most. But make sure you are using biodegradable litter. The Lantern explains that other litter is made from clay, which is produced by strip mining.
