This is kinda similar to how our neighborhood cat composts his stuff, except he doesn't use filter fabric.

Thanks Andrew.

This is somewhat like how i used to get rid of the poo from a 160 pound half ST. Barnard half Newfoundland dog i used to have. Sherman was a very big eater, and pooper too.

The difference in the methods was i made the hole a little deeper (2 feet), and planted a 2 1/2 foot long plastic pipe on top of the rocks. Any pipe 8 inches or larger will work. The bottom foot of the pipe underground had large holes drilled in it. Then i poured more rocks around the outside of the pipe until 6" below ground level. The top 6 inches was filled in with soil.

The advantage of the pipe is you can slip a end cap on the pipe and not worry about smells or stepping into the hole.

I bought a 10' stick of pipe, that made 4 of the potty holes. Then located them around the place so I didn't have to hull the poo too far. I didn't have to worry about the holes filling up too quickly. With 4 holes it always seemed that the holes had a lot in them but they never got full. So i never had to clean them out. Something i probably would have had to do with only one hole.

BTW: one of the potty holes was planted near a berry bush. It got 3 times as large as the other bushes planted at the same time. Had better berries too.
