Speaking of Cats - teach them to poop in their own yards!

Here in louisiana where it doesn't freeze much, there are parasites in cat poop that can make humans blind, esp. children. I like cats here, cause they kill millions of bayou rats, which are a big problem at my place. And why I have a "killer" cat myself. But cats are feral here successfully, and hence, too much poop. Have used all kinds of netting and chicken wire to keep them from pooping in the edible garden. ldc
