Lots of good ideas. What tickled me so much was the advice they gave that was supposed to be so strange and progressive, and it's something I already did, made up out of my own head! One was their advice for getting rid of groundhogs burrowing near and raiding their gardens. They advise pouring used kitty litter down the main burrow opening until the geeberts get out of Dodge. I totally did that with some skunks that moved in--they were hanging out under my hay shed and spraying under my open bedroom window at night. I found a big burrow in the back pasture that looked about the size and shape of a skunk, and poured poopy, peey used kitty litter down it one evening. It was all dug out and kicked away in the next couple of days. I kept pouring more in whenever I had enough to plug up the tunnel, they kept kicking it out, but finally they moved out. But Good. Forever. I figured they thought it stank.
Come to think of it, that was sure the only time in my life I wished I had more used kitty litter to dispose of. Being a life-long cat lover, it has always been such a bulky, filthy problem.
