Doug, Tis be true that you can even buy the "pee" of various critters in concentrated form (don't ask) in a bottle. Depending on what you're trying to keep away you buy Mountain Lion, Coyote, etc. "pee in a bottle" Hummm reminds of an Irish joke--he said piss in the bottle and the fight was on. <g> There is a site where you can buy all sorts of repellents for various critters, but alas no mention of bears or deer: http://www.bugspray.com/catalog/products/page1.html There is a product that is a garlic concentrate that keeps the deer from nibbling on your plants.
