Excellant answer Tom, the only thing that i could add you might enjoy is a piece of scout trivia.Scouts of old also peed like a cat. A scape of the foot and then covering it up vs modern camper that pee like a dog on a tree. A cat is trying to hide his presence and a dog is trying to announce his. I use to think this was a bit much until I talked to Specops freinds who said they used a pee can at their hides for the same reason and then bury it as far from their hides as possible.
