I think I found scientific proof that skunks are at the top of the food chain. I've seen bears attack wolves, mountain lions, elk and bison and win just about every time. I've never seen a bear successfully take down a skunk including this big guy that got schooled.
In the west, we know that you have to be careful with your food when you're in bear country. A family (not in the west) made the mistake of cooking with the windows open and ended up with a very large uninvited guest.
